how can I segment my object from background based on texture?

My project is based on texture segmentation. My first step is to separate my object from the background. How can I proceed with this?

As a first step, try typing Texture into the help and see a list of functions you can try:

Texture Analysis

Entropy, range, and standard deviation filtering; create gray-level co-occurrence matrix
Functions

entropy  Entropy of grayscale image
entropyfilt  Local entropy of grayscale image
rangefilt  Local range of image
stdfilt  Local standard deviation of image

Then run them on your image. Then threshold to create a binary image, label blobs, and call regionprops(). See my Image Segmentation Tutorial for more details: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
