Shape-from-Shading (SFS)是一种通过分析图像中的光照信息推断物体表面形状的技术。在使用SFS计算目标图像中每个像素的高度时,首先需要根据光照方程建立影像亮度和法线之间的关系模型。然后,通过解决反问题,反推出每个像素的表面法线方向,进而计算其高度值。这涉及到对光照条件、摄像机参数等因素的准确建模和求解。通过迭

SfT is closely related to some other vision problems, namely optical flow, scene flow, monocular depth reconstruction, pose estimation and Shape-from-Shading. However, SfT is unique in its own right as it has specific inputs-outputs and challenges. As a consequence, existing methods to these ...

These individual differences are understandable, as shading and disparity cues were in conflict for the bright-valley stimuli, and individuals vary in the extent to which they see depth from binocular disparity [6]. Furthermore, the correlation between individual differences in perceived glow and ...
