Shape from shading是由Horn于1980年提出的一种单幅图像恢复三维信息的一种方法(Single Image-based Reconstruction)。对于Lambert表面具有较好的效果。下面简要的介绍一下其基本步骤和原理: 1. 得到灰度图像I。 可以利用如下关系式计算: gray = 0.3r + 0.59g + 0.11b; 2. 求出变换到光源坐标系的变换矩阵R 已知...

Shading correction was performed on image stacks with BaSiC56 in ImageJ and, finally, maximum projection was performed over the whole stack. Preprocessing Regions of interest (ROIs) were detected automatically from raw calcium movies using Suite2p54. Fluorescence traces, F, were detrended by ...
Contribute both surface height and foam values for shading(为着色提供“曲面高度”和“泡沫”值) Can be either free-moving or tethered to floating objects(波粒子可以自由移动,也可以系在浮动对象上) Here is a cross section profile of a single wave particle. Yuksel et al. use a cosine curve to...
However, another alternative is to uti- lize continuous shape features and convey the shape through shading. We try to render such continuous features into each pixel of an image plane as shape-cues. Therefore, the shape of a 3D object is implied in the 2D image from which will produce ...
