Description

estimate_tilt_zcestimate_tilt_zcestimate_tilt_zcEstimateTiltZcEstimateTiltZc estimates the tilt of a light source, i.e. the angle between the light source and the x-axis after projection into the xy-plane, from the image ImageImageImageImageimage using the algorithm of Zheng and Chellappa.
