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 don't have the computer vision system toolbox so I can't try that code. The lips you're using are very dark and very low contrast. They're hardly any different in color than the surrounding skin so I'm not surprised that you're having trouble. You're not going to solve it with any simple code that's only a dozen lines long.

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.

Dear Image Analyst, is there a code where i want to track the lip movement? i dont want to read lips, i just want to track them while they are moving in real time. Is that possible?

Sure. You can use deep learning - that's what Apple does with their new animoje app. I haven't done it personally so I don't have code to give you.
