I am having a problem while using imwrite after performing DWT and IDWT operations on an gray image.
the problem is that after the imwrite operation when i click on the resulting image file all that i am able to view is a white background instead of an image.
Is there any method to overcome this problem.
for example: if x is an m*n gray scale image then what i have done is
[A,B,C,D]=dwt2(x,'haar');
…..
…..
…..
here i have done some manipulations on the sub-bands(B,C,D)
…..
…..
…..
y=idwt2(A,B,C,D,'haar');
imwrite(y,'C:\Users\HOME\Desktop\IMAGEPROCESS','jpg');
After all these operations when i use imshow(y,[]) the correct image is being displayed. But its not the same case when i try to open the JPG image file(named IMAGEPROCESS in the Eg) as a result of the imwrite operation.
KINDLY HELP
