I have completed extraction of skin region, but unable to apply exact viola-john algorithm on it to achieve the face detection part. code is stated below: I=imread('k001.jpg'); figure,imshow(I);
%%%skin region in rgb image%% if(size(I, 3) > 1) final_image = zeros(size(I,1), size(I,2)); for i = 1:size(I,1) for j = 1:size(I,2) R = I(i,j,1); G = I(i,j,2); B = I(i,j,3);
if(R > 95 && G > 40 && B > 20) v = [R,G,B]; if((max(v) - min(v)) > 15) if(abs(R-G) > 15 && R > G && R > B)
%it is a skin final_image(i,j) = 1; end end end end end end %%% added figure, imshow(final_image); disp('before'); BW=final_image; %else % BW=im2bw(I); % figure, imshow(BW); %end L=bwlabel(BW,4); BB=regionprops(L,'BoundingBox'); BB1=struct2cell(BB); BB2=cell2mat(BB1); [s1,s2]=size(BB2); facedetect=vision.CascadeObjectDetector; after this part unable to apply viola john algorithm for face detection on extracted skin region. extracted skin region result is attached. Kindly help in completing it. thankyou
