How to apply local binary pattern on images and manipulate its results?

I have to apply Local binary patterns on the images to classify the covered and uncovered mouth and then manipulate its results to tell the MATLAB about the pattern of mouth. I am new to MATLAB, so have no idea kindly help me out.

First read LBP, how it works, and what it gives you as output. than you have a binary class problem. For which you have to use a classifier to classify an image as mouth or not mouth.

I am aware of its working principle but unable to evaluate results in programing part. like LBP gives an array of values but how i used them to evaluate

See my attached demo m-file for local binary pattern. This should give you a start. If you need more help after that, attach your adapted code and ask a specific question.

I have understand the principle how it works. your code is so simple to understand rather than available on google. i have attached the results below. From results it is clear that texture is different in both images, but can you please tell me how to manipulate/utilize the results of LBP histogram or localbinarypatternimage to tell the matlab that this is covered mouth and uncovered mouth.

I'm not sure. I don't use LBPs and I don't know why you chose that method to determine if the lips were covered.

Because it is the best classifier to classify the texture difference. Is there anyother method to classify the texture differences.
