can anyone tell me how to read jpeg image in matlab?

Question

can anyone tell me how to read jpeg image in matlab and how to decompose it into detail and approximation image (using wavelet transform) and how to disply that detail and approximated version of it.

Answer 1

1. Set your working directory to the location of the jpeg.
2. type: a = imread('filename.jpg')
3. type: image(a)

filename.jpg should be replaced with your jpeg's file name.
After step 2, it should create a variable out of the jpeg called a.
After step 3, a new window should open with the picture displayed.

This worked with Matlab version 7.0.4.365 (R14) Service Pack 2.

Answer 2

convert it to a bitmap image ang use imread(); to read it...
