Show moreOf the many systems of social organization which members of US society use to categorize other members, gender is one of the most important. The gender system operates to place members of US society into categories, and then allocate labor and resources to those members on the basis of their category membership. In order to better understand the gender system, this study examines the methods by which members of US society use the gender system to place other members into a gender category. First, full facial photographs were taken of a group of participants of varying gender, race, ethnicity, and age. Then, parts of each participant's face were isolated digitally and shown to a second group of participants. This second group was asked to identify the sex and/or gender of the individual in the image, indicate how confident they were in this identification, and then write a brief explanation for why they identified the individual in the image as they did. The analysis conducted by this study supports three findings. First, though the gender categories "male" and "female" are still widely predominant, other categories such as "genderqueer" are seeing use as well. Second, the mouth and lips tend to be seen as more important indicators of gender than other facial features. Finally, while the race and gender category membership of the member doing the categorizing has little or no interaction with the gender categorization process, the race and gender category membership of the member being categorized does have a significant interaction.

Appearance-related commentary can be positive or negative. Such commentary has been shown to negatively affect the mental health and well-being of women in a well-documented body of research. There is limited research on this topic pertaining to males. The purpose of this study was to investigate the effects of appearance-related commentary in men. Results indicate that men who receive more negative commentary are more likely to experience eating pathology, body dissatisfaction, distress from...
Show moreAppearance-related commentary can be positive or negative. Such commentary has been shown to negatively affect the mental health and well-being of women in a well-documented body of research. There is limited research on this topic pertaining to males. The purpose of this study was to investigate the effects of appearance-related commentary in men. Results indicate that men who receive more negative commentary are more likely to experience eating pathology, body dissatisfaction, distress from commentary, and participate in compulsive exercising and appearance-change behaviors. However, men that receive positive commentary are likely to experience more positive outcomes, reporting less dissatisfaction and pathology but more appearance-change behaviors. It appears that men are affected by negative, appearance-related commentary in the same ways that women are, but that they experience positive commentary in a more direct and appropriate manner. Additionally, self-objectification, a covariate found to interact in similar relations with women, was not found to account for any of the variance between appearance-related feedback and outcomes.

In today's society a beauty ideal exists in America, which attempts to define female beauty as fitting into a certain mold. Certain characteristics have been deemed the most attractive when it comes to female physical attractiveness, and an ideal image of beauty has been presented by the media.

Show moreIn today's society a beauty ideal exists in America, which attempts to define female beauty as fitting into a certain mold. Certain characteristics have been deemed the most attractive when it comes to female physical attractiveness, and an ideal image of beauty has been presented by the media. This research focuses on whether or not everyone buys into that beauty ideal, and examines the impact that a person's sex and race has on the physical characteristics which that individual defines as the most appealing. Surveys were administered to 300 UCF students age 18-35. Participants were asked about ten different physical characteristics relating to women, and were asked to choose the characteristic among each group that they found the most physically attractive or beautiful. The study showed that both sex and racial differences do exist, and that there are variations in what different people consider beautiful. Not everyone has the same opinion on what is attractive in regards to the physical appearance of women.

Show moreThe need for real-time video analysis is rapidly increasing in today's world. The decreasing cost of powerful processors and the proliferation of affordable cameras, combined with needs for security, methods for searching the growing collection of video data, and an appetite for high-tech entertainment, have produced an environment where video processing is utilized for a wide variety of applications. Tracking is an element in many of these applications, for purposes like detecting anomalous behavior, classifying video clips, and measuring athletic performance. In this dissertation we focus on augmented reality, but the methods and conclusions are applicable to a wide variety of other areas. In particular, our work deals with achieving real-time performance while tracking with augmented reality systems using a minimum set of commercial hardware. We have built prototypes that use both existing technologies and new algorithms we have developed. While performance improvements would be possible with additional hardware, such as multiple cameras or parallel processors, we have concentrated on getting the most performance with the least equipment. Tracking is a broad research area, but an essential component of an augmented reality system. Tracking of some sort is needed to determine the location of scene augmentation. First, we investigated the effects of illumination on the pixel values recorded by a color video camera. We used the results to track a simple solid-colored object in our first augmented reality application. Our second augmented reality application tracks complex non-rigid objects, namely human faces. In the color experiment, we studied the effects of illumination on the color values recorded by a real camera. Human perception is important for many applications, but our focus is on the RGB values available to tracking algorithms. Since the lighting in most environments where video monitoring is done is close to white, (e.g., fluorescent lights in an office, incandescent lights in a home, or direct and indirect sunlight outside,) we looked at the response to "white" light sources as the intensity varied. The red, green, and blue values recorded by the camera can be converted to a number of other color spaces which have been shown to be invariant to various lighting conditions, including view angle, light angle, light intensity, or light color, using models of the physical properties of reflection. Our experiments show how well these derived quantities actually remained constant with real materials, real lights, and real cameras, while still retaining the ability to discriminate between different colors. This color experiment enabled us to find color spaces that were more invariant to changes in illumination intensity than the ones traditionally used. The first augmented reality application tracks a solid colored rectangle and replaces the rectangle with an image, so it appears that the subject is holding a picture instead. Tracking this simple shape is both easy and hard; easy because of the single color and the shape that can be represented by four points or four lines, and hard because there are fewer features available and the color is affected by illumination changes. Many algorithms for tracking fixed shapes do not run in real time or require rich feature sets. We have created a tracking method for simple solid colored objects that uses color and edge information and is fast enough for real-time operation. We also demonstrate a fast deinterlacing method to avoid "tearing" of fast moving edges when recorded by an interlaced camera, and optimization techniques that usually achieved a speedup of about 10 from an implementation that already used optimized image processing library routines. Human faces are complex objects that differ between individuals and undergo non-rigid transformations. Our second augmented reality application detects faces, determines their initial pose, and then tracks changes in real time. The results are displayed as virtual objects overlaid on the real video image. We used existing algorithms for motion detection and face detection. We present a novel method for determining the initial face pose in real time using symmetry. Our face tracking uses existing point tracking methods as well as extensions to Active Appearance Models (AAMs). We also give a new method for integrating detection and tracking data and leveraging the temporal coherence in video data to mitigate the false positive detections. While many face tracking applications assume exactly one face is in the image, our techniques can handle any number of faces. The color experiment along with the two augmented reality applications provide improvements in understanding the effects of illumination intensity changes on recorded colors, as well as better real-time methods for detection and tracking of solid shapes and human faces for augmented reality. These techniques can be applied to other real-time video analysis tasks, such as surveillance and video analysis.

The bias against attractiveness is fairly implicit and furthermore, powerfully impacts people's subsequent impressions of and behaviors toward others (Cash, Gillen, (&) Burns, 1977; Dion et al., 1972). Pallet, Link and Lee (2010) examined the effect of various facial spatial configurations on attractiveness and found that raters rated faces as most attractive when the eye-to-mouth ratio approximated 36% of the face length (the "golden ratio"), which coincides with the measurements of an...
Show moreThe bias against attractiveness is fairly implicit and furthermore, powerfully impacts people's subsequent impressions of and behaviors toward others (Cash, Gillen, (&) Burns, 1977; Dion et al., 1972). Pallet, Link and Lee (2010) examined the effect of various facial spatial configurations on attractiveness and found that raters rated faces as most attractive when the eye-to-mouth ratio approximated 36% of the face length (the "golden ratio"), which coincides with the measurements of an average and thus more attractive face. The present study examined the extent to which the distance of these objectively measured facial features affected mentors' perceptions of their prot(&)#233;g(&)#233;s, the subsequent mentoring given to them, and the prot(&)#233;g(&)#233;s' own behavior (e.g. seek feedback, request specific information).The gender composition of the mentor-prot(&)#233;g(&)#233; dyad was expected to moderate these relationships. I also examined whether, given the expected effects of facial measurements, withholding access to visual cues would affect mentor perceptions and behavior. Participants were 118 mentor/prot(&)#233;g(&)#233; dyads from a large Southeastern university who volunteered to participate in a formal online peer mentoring program. After seeing their prot(&)#233;g(&)#233;s' profiles (and for those in the experimental condition, a picture), mentors chatted with their prot(&)#233;g(&)#233;s once a week for 30 minutes for a total of 4 weeks. Results indicated that prot(&)#233;g(&)#233;s with facial features moderately distant from the golden ratio were perceived as more similar by mentors in same-gender dyads and received greater mentoring than did prot(&)#233;g(&)#233;s closest and farthest from the golden ratio. In opposite-gender dyads, however, mentors reported greater similarity toward those that were farthest from the golden ratio but provided the greatest mentoring to those closest to the golden ratio. The relationship between facial measurements and prot(&)#233;g(&)#233; proactivity was moderated by whether or not their mentor had access to their picture. While prot(&)#233;g(&)#233;s closest to the ratio were more proactive in the picture condition, those that were farthest from it were more proactive in the non-picture condition. Proactivity was as expected associated with greater levels of mentoring, which was ultimately related to a more fulfilled and beneficial relationship for prot(&)#233;g(&)#233;s (i.e. less stress, greater self-efficacy and satisfaction). The results of this study indicate that facial measurements are associated with both differences in mentor and in prot(&)#233;g(&)#233; behavior and that the specific nature of these relationships differs as a function of gender composition. Implications for practice and theory will be discussed.
