描述
estimate_tilt_zcestimate_tilt_zcEstimateTiltZcEstimateTiltZcEstimateTiltZcestimate_tilt_zc 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 ImageImageImageImageimageimage using
the algorithm of Zheng and Chellappa.
执行信息
- 多线程类型：可重入（与非独占算子并行运行）。
- 多线程作用域：全局（可从任何线程调用）。
- 在元组级别上自动并行化。
