how to do a co segmentation process using Graph Cut in an image?

(i) Fix the total number of clusters as N.

(ii) Divide the total feature space into small regions from 1 to N.

(iii) Initial speed population size is set as p.

(iv) Calculate the fitness value using fitness function and perform cross over operation and

generate 95% new individuals. Now the total population size becomes 0.95 * p.

(v) Sort all the individuals and select the

p fit individuals for the next generation.

i have to execute graphcut co-segmentation process using above algorithms?
