Pollen recognition is one of the most active research areas in field of ecological modeling. It is done
either via microscopic image analysis of pollen grains or via chemical components analysis. In this
paper, the authors were interested in pollen images analysis, in which they proposed an approach for
image segmentation in order to detect pollen grains in the microscopic images. The approach starts
by generating two pixels using genetic algorithms where one pixel of the selected ones is a pollen
pixel while the other is background pixels. Then the authors used k-means algorithm for image pixels
clustering to segment the input image. After that they classified the segmented images using machine
learning technics, and finally, they used taboo search to save the best pixels chosen by genetic algorithm
based on the obtained accuracy as fitness function. The obtained results proved the efficiency of the
proposed system where it could recognize 96.4% of the pollen grains.
