Analysis of shape from shading techniques
Ruo Zhang, Pin-Sing Tsai, Cryer, Shah · 1994
Since the first shape-from-shading technique was developed by B.K.P. Horn in the early 1970s, different approaches have been continuously emerging in the past two decades. Some of them, improve existing techniques, while others are completely new approaches. However, there is no literature on, the comparison and performance analysis of these techniques. This paper provides comparison and analysis of these techniques.>
