Hey Nurul,
I am not sure what exactly you want to threshold, so here is a general solution.
Step1 : Convert this to grayscale image, either using rgb2gray() or other appropriate functions.
Step2 : Examine the histogram of the image using imhist(), and identify the threshold value.
Step3 : Just threshold it!
I hope it helps ;)

Why not use my interactive thresholding app. I just uploaded an updated version today: http://www.mathworks.com/matlabcentral/fileexchange/?term=authorid%3A31862
