</matlabcentral/answers/uploaded_files/27943/BrainMRI-GadLesion.jpg> Sir in my code in the "Remove_callback " part when I want to convert the image in RGB to Gray using the code rgb2gray its showing the following errors. Error using rgb2gray>parse_inputs (line 81) MAP must be a m x 3 array.

how can I solve it?

Prakash - what are the dimensions for I? The error message is telling you that the input matrix must be three dimensional. Is this the case? Use the debugger to step through your code to verify.

Prakash - rgb2gray converts an RGB (true colour) image to grayscale. This means that it requires the input image to be three dimensional, one dimension for each of the red, green, and blue channels. So something like
rgbImg = uint8(randi(255,200,300,3));
Note that the above 200x300 matrix has three dimensions. I suspect that your I matrix is just one- or two-dimensional.
