I have performed dwt2 on a image ,and have its coefficient,and sampled it,now i want to quantise the cA,cH coefficients to single image ,please help
the size of cA after sampling ,is 128x128 and cH after sampling is 128x128,now i want to perform quantization on cA,cH and get a single image please help
I don't know what you mean. There is a new imquantize() in the Image Processing Toolbox - I think it started in R2012b. See if that will do what you want.
If you want to do stitching of images instead, just put the in brackets:
horizontallyStitchedImage = [image1, image2] verticallyStitchedImage = [image1; image2]
Of course the dimension (number of rows or columns) along the stitching seam must be equal.
