Downloads for Project 1:
Input image Lena.org (256x256 8bits/pixel gray level image in raw format)
You can convert the raw format to a bitmap file by using the following two applications:
· For Windows system: covert2bmp.exe
· For Unix/Linux: conver2bmp
You can use any image viewer to view the bitmap
image. You should also use these programs to convert your reconstructed images
to bitmap format and see what you have got.
***These programs are to be used only in this project. They are not built for
general use!
