  8. Skin Color Detection

  9. Color Space • Correlation-coefficient • R,G => 95.66% • R,B => 83.4% • B,G => 92.34%

  10. Color Space Other Color Space RGB

  11. Color Space • CIE • CIEXYZ · CIELAB · CIECAM02 · CIELUV · Yuv · CIEUVW · CIE RGB • YUV • YUV (PAL) · YDbDr (SECAM) · YIQ (NTSC) · YCbCr · YPbPr · xvYCC • Other • LMS · HSL, HSV · CMYK ·… …

  12. YCbCr • Y = 0.299R + 0.587G + 0.114B • U = -0.147R - 0.289G + 0.436B • V = 0.615R - 0.515G - 0.100B • R = Y + 1.14V • G = Y - 0.39U - 0.58V • B = Y + 2.03U

  13. YCbCr • Correlation-coefficient • Y,Cb => -28.4% • Y,Cr => 18.68% • Cb,Cr => -74.41%
