"i need the output without the those black areas and those black pixels should be filled with the image pixels"

There are no image pixels available to fill these areas. That's why they're black. Unless you have another image that shows what should be in these areas, what you're asking is impossible.

i mean the black portion should be removed without loosing the information of the image.

Since an image is always rectangular, the only way you can remove the black portion is either by replacing it with something else or cropping the image into a smaller rectangle.

Unless you have another image to tell you what the 'something else' should be you can only take a guess or use a solid colour( matlab uses black).

Cropping the image will obviously loose some information at the same time.
