Face Recognition using Fused Diagonal and Matrix Features

Face recognition with less information availability in terms of the number of image samples is a challenging task A simple and efficient method for face recognition is proposed in this paper to address small sample size problem and rotation variation of input images The robert s operator is used as edge detection method to elicit borders to crop the facial part and then all cropped images are resized to a uniform 50 50 size to complete the preprocessing step Preprocessed test images are rotated in different angles to check the robustness of proposed algorithm All preprocessed images are partitioned into one hundred 5 5 equal size parts The matrix 2-norm infinite norm trace and rank are elicited for each of 5 5 part and respectively averaged to yield on hundred matrix features Another one hundred diagonal features are extracted by applying a 3 3 mask on each image Final one hundred features are obtained by fusing averaged matrix and diogonal features Euclidian distance measure is used for comparision of database and query image features The results are comparitively better on three publically availabe datasets compared to existing method

Performance analysis of different matrix decomposition methods on face recognition

Applications using face biometric are ubiquitous in various domains. We propose an efficient method using Discrete Wavelet Transform (DWT), Extended Directional Binary codes (EDBC), three matrix decompositions and Singular Value Decomposition (SVD) for face recognition. The combined effect of Schur, Hessenberg and QR matrix decompositions are utilized with existing algorithm. The discrimination power between two different persons is justified using Average Overall Deviation (AOD) parameter. Fused EDBC and SVD features are considered for performance calculation. City-block and Euclidean Distance (ED) measure is used for matching. Performance is improved on YALE, GTAV and ORL face databases compared with existing methods

Pengenalan Wajah Menggunakan Implementasi T-shape Mask Pada Two Dimentional Linear Discriminant Analysis Dan Support Vector Machine

. Face recognition is the identification process to recognize a person\u27s face. Many studies have been developing face recognition methods, one of which is the Two Dimensional Linear Discriminant Analysis (TDLDA) which has pretty good accuracy results with the method of classification Support Vector Machine (SVM). With more training data can add computational time. TDLDA using all the piksel image as input to be processed for feature extraction. Though not all the objects in the area of the face is a significant feature in face recognition. In this study, the proposed use of the T-shape with only use a significant part is the eyes, nose, and mouth are integrated with TDLDA and SVM. The result could reduce computing time on face recognition 21.56% faster than TDLDA method. The accuracy of the results in this study was 91% -96% which is close to the level of accuracy without using a mask on the face

The complications of ‘hiring a hubby’: gender relations and the commoditisation of home maintenance in New Zealand

This paper examines the commoditization of traditionally male domestic tasks through interviews with handymen who own franchises in the company ‘Hire a Hubby’ in New Zealand and homeowners who have paid for home repair tasks to be done. Discussions of the commoditization of traditionally female tasks in the home have revealed the emotional conflicts of paying others to care as well as the exploitative and degrading conditions that often arise when work takes place behind closed doors. By examining the working conditions and relationships involved when traditionally male tasks are paid for, this paper raises important questions about the valuing of reproductive labour and the production of gendered identities. The paper argues that while working conditions and rates of pay for ‘hubbies’ are better than those for people undertaking commoditized forms of traditionally female domestic labour, the negotiation of this work is still complex and implicated in gendered relations and identities. Working on the home was described by interviewees as an expression of care for family and a performance of the ‘right’ way to be a ‘Kiwi bloke’ and a father. Paying others to do this labour can imply a failure in a duty of care and in the performance of masculinity

The expectations and perceptions of incoming freshmen at UNI

As colleges and universities have become increasingly competitive in their recruitment and retention of students, they have placed greater emphasis on the quality of the freshman experience. The nature of this experience serves as the focus of this study. This paper draws upon qualitative data about the perceptions and expectations of students beginning their first year of enrollment at the University of Northern Iowa. In doing so, it examines students\u27 expectations and perceptions regarding their (1) prospective academic workload, (2) relationships with faculty, (3) relationships with peers, and ( 4) co-curricular involvements. While this study examines only the University of Northern Iowa, it offers findings that may have broader benefits. As Thompson and Fretz (1991, p. 446) observed, findings from individual institutions have value in helping to explain behaviors that may be particular to inhabitants of that institution and consequently, useful on the campus wide level . The University of Northern Iowa is a mid-sized state university located in Cedar Falls, Iowa. In the Fall semester of 1997, undergraduate enrollment totaled 11, 654, while graduate student enrollment totaled 1,454. Women comprised 58.5% of the student population. A total of 1,957 students entered in the Fall semester of 1997, making up 16.8% of total undergraduate enrollment. Of these new students, 94.8% entered as Iowa residents. Based on total undergraduate enrollment, 4% of students were classified as ethnic minorities, including 2% Black students, and the remaining 2% were categorized as Asian, Hispanic and American Indian students (Wyatt & Carlson, 1997). Because most attrition takes place between students\u27 freshman and sophomore years of college (Beal & Noel, 1980), a close examination of the freshman year experience provides insight into students\u27 adjustment process, and their resulting decisions of whether or not to continue attending an institution. Of the 2,012 new freshman students who enrolled in the Fall semester of 1996, 92.4% returned in the following Spring semester of 1997, and 82.0% returned a year after enrollment in the fall of 1997 (Wyatt & Carlson, 1997). Upon acceptance to UNI, 91.5% of the new freshmen students entering in the Fall of 1997 attended one of the two-day orientation sessions during June and July. At these sessions, they registered for classes, met current students and staff, toured the campus and residence halls, interacted with other incoming students, and were introduced to many of the University\u27s services. These students then began Fall semester classes in mid-August. These initial activities constitute students\u27 first experiences with the university, and provide a starting point for the individuals in this project. In this study, I examine 1) the perceptions and expectations that these students carried with them into their first semester of classes and 2) how these perceptions and expectations changed over the course of the students\u27 first academic year. In doing so, I draw upon in-depth, qualitative interviews of a stratified sample of 12 UNI freshmen. These interviews enabled me to develop thick, rich descriptions of the perceptions of these students based on their current lived experiences. The sample of 12 students was selected from a complete list of registered incoming students for the Fall semester of 1997. The sample included six women and six men. Two of these students were African American, one was Asian American and two were from out-of-state. The interview questions focused on a variety of issues, including residence hall living, the classroom setting, interactions with professors, social activities, dating relationships, interactions with parents, decisions about a major, sources of anxiety, and the availability of support systems. This information was supplemented by data gathered during follow-up interviews with the same students at the beginning of the Spring semester of 1998. These second-stage interviews explored the students\u27 influential experiences since beginning college, disappointments, relationships with roommates, perceptions of academic workload and classroom atmosphere, experiences going home for winter break, attitudes toward finals; and overall changes in expectations. By the time the second set of interviews took place, two of the respondents had transferred to different institutions, one to an out-of-state community college and the other to a different state university in Iowa, and thus were interviewed by phone. In addition to discussing the above topics, these students also discussed their reasons for choosing to leave UNI. During the interview process, several themes emerged which reveal how this group of students has experienced their first year of enrollment at the University of Northern Iowa. In the following analysis, these themes will be identified, developed and analyzed
