I have no experience with lip reading. My only guidance is to look at the papers of people who do have that experience and have succeeded and published papers on the subject. Their algorithms would be better than anything I could offer you. However it looks like you've Accepted the answer below so everyone assumes you used that and now everything is working.

Yes Sir, I have applied the process to extract lip region & done it.
Thank you again.

A simple example to guide you through the process:
% Let's assume img is your image matrix and lipCoords is an Nx2 array of
% (x, y) coordinates outlining the lip region.
% For example:
% lipCoords = [x1, y1; x2, y2; ... ; xN, yN];
% Extract the lip region using the binary mask
lipRegion = img;
lipRegion(~mask) = 0; % This sets all pixels outside the lip region to 0
% Display the original image and the extracted lip region
figure;
subplot(1, 2, 1);
imshow(img);
title('Original Image');
subplot(1, 2, 2);
imshow(lipRegion);
title('Extracted Lip Region');
In the code:
• poly2mask is a function that converts a polygon to a region mask.
• lipCoords is assumed to be an array of coordinates for the lip region.
• lipRegion is the part of the image with the lips isolated.
Please replace img and lipCoords with your actual image and coordinates. If the coordinates are in a different format or if you have a list of points that do not form a closed polygon, you might need to use different methods to create the mask.
