Name
estimate_tilt_lrestimate_tilt_lrEstimateTiltLrEstimateTiltLr
— Estimate the tilt of a light source.
Signature
Herror estimate_tilt_lr(const Hobject Image, double* Tilt)
Herror T_estimate_tilt_lr(const Hobject Image, Htuple* Tilt)
Description
estimate_tilt_lrestimate_tilt_lrEstimateTiltLrEstimateTiltLrEstimateTiltLr
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 Lee and Rosenfeld.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.
Parameters
ImageImageImageImageimage
(input_object) singlechannelimage(-array) →

Angle between the light source and the x-axis after
projection into the xy-plane (in degrees).
Result
estimate_tilt_lrestimate_tilt_lrEstimateTiltLrEstimateTiltLrEstimateTiltLr
always returns the value 2 (H_MSG_TRUE).
