Webb25 feb. 2012 · Shape-from-shading (also known as photoclinometry) is a method for determining the shape of a surface from its image. For a surface of constant albedo, the brightness at a point (x,y) in the image is related to the gradients (p,q) by the following expression i (x,y) = a R [p (x,y),q (x,y)] WebbHere we show how the shape-from-shading problem can be solved when the reflectance …
