MATLAB: How to extract lip region from facial features

Image Processing Toolboxliplip readingskin

Hi,
I am newbie for matlab , from matlab forums i have tried to get lip region ,but exact shape i cannot get .so please let me know where i have make mistake let me know,below code followed?
    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;

I have told you here in this link. Basically no one here is a lip reading expert, and there's no lip reading toolbox, so I pointed you to a place where you will find algorithms from lip reading experts. I know it's a little bit of work on your part to contact the authors or to try to write code to implement their algorithms, but since you don't seem to want to do it yourself, that's your only other option, unless you want to hire some consultant or university to do it for you. Good luck.
