Block Differential Image

Face Detection and Capturing System using Face skin color

Face detection using by boundary property of block differential image

Summary

Applications

 

 Block Differential Image


   - Block differential image is made analysis 8 by 8 block in differential image
     that present frame subtract previous frame.

 Face Detection and Capturing System using Face skin color 


  - YIQ color model

  - Skin color detection in block differential image

  - Define the characteristic of face region
    - Face size: 12 pixel - 100 pixel
    - Face rate of horizontal and vertical: less than 2/3
    - Percentage of skin color in block: more than 60%

 Face detection using by boundary property of block differential image


  - Minimize variation of skin color by illumination

  - Find head region to analyze boundary of block differential image and
    detect face region in that using similarity for skin color
