Implementation of simple photometric stereo like below picture.

Ubuntu 18.04
Python3.6

• OpenCV4
• numpy
• sys
• os
• scipy

Prepare proper images and masks for photometric stereo. In order to estimate light source direction, this code require chrome images that taken same lighting environment.

Note that the images used in the example program are taken from the following project page: https://courses.cs.washington.edu/courses/cse455/10wi/projects/project4/psmImages_png.zip

python main.py argvs[1] argvs[2] argvs[3]



argvs[1]  :  path to input folder   
-->  {abc}/{abc}.{number}.png, {abc}/{abc}.mask.png

argvs[2]  :  path to chrome folder   
-->  argvs[1] and argvs[2] have to taken same lighting condition

argvs[3]  :  number of image

Options:
windowsize: see mask2tiny function
