Try "help bwlabel"... Essentially, this function will numerically label each connected component of your image. You can then work on the corresponding values you get from the eyes and lips areas of your image as you wish.

Mr. yukteshwaraditya singh parihar

We are doing the final year project "sentiment detection through facial expression". Is your project completed? we need some guidance as we are working on color image.

Hi,

         Did you get lip region for facial expression ? if get let me know how to get ?
below code i have tried but it's not exact shape shown ?
 YIQ = rgb2ntsc(hue1);
     Y1 = YIQ(:,:,1);
    I1 = YIQ(:,:,2);
    Q = YIQ(:,:,3);
    J = imadjust(Y1);
    t = graythresh(blue_Image);
imCoin = (red_Image > hueThresholdHigh);
    K = medfilt2(red_Image);
    [level1 EM]= graythresh(K);
    BW_lip = im2bw(red_Image);
    Binary_Hue = red_Image > T;
    level = graythresh(J);
   binary_Image = im2bw(J,level);
   [imx,imy]=size(binary_Image);
   bw_Fill= imfill(binary_Image,'holes');
   labeledImage = bwlabel(bw_Fill, 8);
   blobMeasurements = regionprops(labeledImage, 'area');
   areas = [blobMeasurements.Area];
   [maxArea largestBlobIndex] = max(areas);
    bw_area = bwareaopen(bw_Fill ,2500);
   BWnobord = imclearborder(bw_area, 4);
   seD = strel('disk',1);
%     BWfinal = imerode(BWnobord,seD);
    BWfinal = imerode(BWnobord,seD);
    BWoutline = bwperim(bw_area);
    Segout = mouthcrop;
    Segout(BWoutline) = 255;
