A process for producing rectangular aggregates in a digital image in which a user is directed to put annotation relating to the image. The process includes implementing a divergence level calculation procedure for categorizing the pixels of the image either above or below a divergence threshold. Then, imposing a grid on the image, of which each grid element is larger than a pixel. Further, implementing a grid element homogeneity calculation procedure, by employing homogeneity threshold for classifying the grid elements as being either homogeneous or non-homogeneous. Further, implementing a rectangular aggregate formation procedure, in which homogeneous grid elements are grouped in rectangles. |
