after applying curvelets transformation, how to get the images with multi resolution. which are divided based on frequency,how to create image of different frequencies

munna,

I've never used curvelets but presume they're a subclass of wavelet.

Plot the array that you get out of the curvelet transformation. You'll see the multiresolution images in the plot; they are tessellated together in the one array.

Exactly how they are tessellated depends on the order and type of the transformation, but you can find that out by looking at the plot then extract sub regions of the transformed array if you need the multi resolution images explicitly.

Best regards

Tom

sir i have seen that demo sir, actually i want to retrieve images from that sir, i don't know how to create image with that curve lets co-efficients , i mean to say i want layers of the image,, i have to eliminate one layer by layer then check the snr ration sir.. may know,how to group n make image
