Estimate the tilt of a light source.
estimate_tilt_lr 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 Image using the algorithm of Lee and Rosenfeld.
|
Image (input_object) |
image(-array) -> object |
| Image for which the tilt is to be estimated. | |
|
Tilt (output_control) |
angle.deg(-array) -> real |
| Angle between the light source and the x-axis after projection into the xy-plane (in degrees). | |
estimate_tilt_lr always returns the value TRUE.
