How to estimate depth from gradient?
显示 更早的评论
Hello,
I have a gradient of an image:
mask = fspecial('sobel');
mask2 = mask';
dX = imfilter(image, mask);
dY = imfilter(image, mask2);
And I want to estimate depth from the gradient, any thoughts on how to do so?
Thanks in advance!

Why do you think that might be possible?

Don't call your image variable "image" - that is the name of a built-in function that you shouldn't destroy/override. What do the "intensity" values of your image represent? A distance, like it's a topographic, profilometry, or Kinect image?

If your pixels represent depth (i.e. change in a third dimension), then integrating the gradient should give you height. This means you'll need to know the height at one location.
