Development of Shape Recovery Method for Endoscope Image Using Point Light Source Illumination

点击翻译按钮获取中文摘要

The purpose of this research is to develop the 3D shape from endoscope image(s) under point light source illumination and perspective projection. After removing the specular reflectance, a point with the local maximum intensity is set as an initial point in the diffuse reflectance component image. The approach performs that whole shape is recovered with estimating depth of the neighboring points using the updating equation of the depth, while another approach was also developed to recover the depth map using two images with moving both camera and point light source.
