Name

estimate_tilt_lrestimate_tilt_lrEstimateTiltLrEstimateTiltLr — Estimate the tilt of a light source.

Signature

estimate_tilt_lr(Image : : : 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) → object (byte)

Image for which the tilt is to be estimated.

TiltTiltTiltTilttilt (output_control) angle.deg(-array) → (real)

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).
