Center-Surround Processing
• Why we use Center-Surround processing???
Centre-surround is a simple way ofCentre-surround is a simple way ofpreprocessing an image, which is likepreprocessing an image, which is likefinding lines. Basically if a pixel hasfinding lines. Basically if a pixel hasmostly white around it, it is an emptymostly white around it, it is an emptyarea, if it’s half white and half black, thenarea, if it’s half white and half black, thenit’s probably an edge, etc.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 Local Search --- In the process of local search, users are able to do a search to search, users are able to do a search to find all matched pixels in different find all matched pixels in different position within the defined image. position within the defined image.
• Normal Search --- It is possible for user Normal Search --- It is possible for user to search through face images with the to search through face images with the same shot angle on the local disk, and same shot angle on the local disk, and find matched pixels at the exact same find matched pixels at the exact same position with the defined condition. In position with the defined condition. In the program, it is one types of same the program, it is one types of same location search. location search.
![Page 7: Data Search Tool For Face Recognition Presented by Student: Yan Gao Student Id: u2581609 COMP6703 Demonstration Supervisor: Professor Tom Gedeon](https://reader031.vdocument.in/reader031/viewer/2022033106/56649d6b5503460f94a49e6c/html5/thumbnails/7.jpg)
Key Terminology (2)
• Rough search --- It is another type of Rough search --- It is another type of same location search, the only same location search, the only difference between normal search and difference between normal search and rough search is that it is possible for rough search is that it is possible for user to search matched pixels with 0 to user to search matched pixels with 0 to ++5 pixels variation. 5 pixels variation.
• Variable search --- it means that user Variable search --- it means that user can define search type and the range of can define search type and the range of search images through parameters in search images through parameters in the user interface, then start a search to the user interface, then start a search to find the matched pixels with the defined find the matched pixels with the defined condition.condition.
