I have extracted features of all images and have calculated EUCLIDEAN DISTANCE and have sorted
[Out ind] = sort(Distance_final);
from the ind value i have calculated ,recall and precision,after that i have performed PSO,and all my values in ind is sorted,now if i performprecesion and recall,those value must improve,but it is not improving ,please help

No amount of PSO to simulate a sort is going to change the basic features of the test image or of the database of images. The precision and recall are going to remain exactly the same.
