This file contains functions used to segment the contour of single cell with a seed point. This file contains functions used to segment the contour of single cell with a seed point.
The principal algorithm is : The principal algorithm is dynamic programming:
1. generate a series of rays of different direnctions from the seed of the cell detected, 1. generate a series of rays of different direnctions from the seed of the cell detected,
