how to find multi scale edge detection using bilateral filter

I want to implement multi scale edge detection using bilateral filter.I have done with input image edge detection and found out edge points of bilateral smoothened image.Now,how to find out new edge map image after comparing edge map of original image and edge map of smoothened image and how to implement it multiple times

Are you following some recipe in a paper? It sounds like it.

[aarti sawant]

yes its a recipe of multi scale edge detection using bilateral filter.Is there any way to compare both images to form new edge map

[Image Analyst]

Doesn't the paper tell you that?

[aarti sawant]

That paper tells me to compare those images but how it doesn't tells

Sorry but I don't know, and I can't spend time reinventing "multi scale edge detection using bilateral filter" algorithm that they published for you. It is probably not something they just whipped up in 10 minutes but most likely took them months of work, which I can't afford to do for you.
