Please use punctuation and capitalisation so I don't need to read your drivel 5 times to figure out what you are trying to write.

Also, please describe what you are trying to do in much more detail. You could print out your image, cut the person out with scissors, scan it back in and display the image with Matlab. Alternatively, you could spend years trying to solve this problem well in a programmatic way. What is the context?
