Hi Gunjan,

Would you be able to post an example images. If you're open to it, there may be additional approaches beyond edge detection that could help segment your image, if that is what you are indeed after. I'd love to take a look.

Cheers,

John

Hi Helder, I know for wavelet transform we got low frequency component which we set to zero to get high frequency component (edges). But, for curvelet I haven't got any literature. People are using canny and curvelet which doesn't make sense.Can we use directly curvelet transform for edge detection.
