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!

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?

Thank you for the advice on image variable.
Yes the image intensity values represent a distance.

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.
