Data Search Tool For Face Recognition Presented by Student: Yan Gao Student Id: u COMP6703 Demonstration Supervisor: Professor Tom Gedeon

Overview What is aim for this project??? The aim of this project is to find often occurring conditions in a range of face images.

Requirement What is requirement for this project??? The software is designed as a tool with user interface, for face recognition data search. The tool allows users to set the search condition, and the software is able to search rapidly through a large number of images in local disk, and to keep records of any occurrence of a defined condition.

Center-Surround Processing Why we use Center-Surround processing??? Centre-surround is a simple way of preprocessing an image, which is like finding lines. Basically if a pixel has mostly white around it, it is an empty area, if it’s half white and half black, then it’s probably an edge, etc.

Center-Surround Processing Example Example Surround Value: S1= 255 (White), S2= 255 (White), S3= 255 (White), S4= 255 (White), S5= 255 (White), S6= 255 (White), S7= 255 (White), S8= 255 (White) Centre Value= 0 (Black) Centre Value* 8 < S1 + S2 + S3 + S4 + S5 + S6 + S7 + S8 Conclusion: Centre < Surround (Empty area)

Key Terminology (1) Local Search --- In the process of local search, users are able to do a search to find all matched pixels in different position within the defined image.Local Search --- In the process of local search, users are able to do a search to find all matched pixels in different position within the defined image. Normal Search --- It is possible for user to search through face images with the same shot angle on the local disk, and find matched pixels at the exact same position with the defined condition. In the program, it is one types of same location search.Normal Search --- It is possible for user to search through face images with the same shot angle on the local disk, and find matched pixels at the exact same position with the defined condition. In the program, it is one types of same location search.

Key Terminology (2) Rough search --- It is another type of same location search, the only difference between normal search and rough search is that it is possible for user to search matched pixels with 0 to +5 pixels variation.Rough search --- It is another type of same location search, the only difference between normal search and rough search is that it is possible for user to search matched pixels with 0 to +5 pixels variation. Variable search --- it means that user can define search type and the range of search images through parameters in the user interface, then start a search to find the matched pixels with the defined condition.Variable search --- it means that user can define search type and the range of search images through parameters in the user interface, then start a search to find the matched pixels with the defined condition.
