Hi surendar. You can start image processing by using matlab. It's a very good tool, it consists of toolboxes with functions for image processing, wavelets.
a very good book for image processing in matlab is "image Processing using matlab by Gonzales, Woods".

I think verilog has not this ability. you should convert image to matrix anywhere (matlab) and use its file as input for verilog (in Modelsim) with 'readmem". after compilation you can save the results with "$fprint" and convert this file (with matlab) to image.

matlab it self can open and control serial port.
Also it support C programming for your own hardware.

First you have to identify the object to be isolated. Then draw a border around that object such that the difference of pixels values along that border crosses a certain threshold.
You can also use a high pass filter on the image and then comparing the output from HPF with the original (by matlab script) find out the border. In this case the d
