Thresholding is an important approach of image segmentation. One of the criteria to select the threshold is two- dimensional (2-D) entropic thresholding. However this method is time-consuming. A hybrid method of GA and ACO is introduced to the 2-D entropic thresholding instead of the exhaustive search. In the proposed method, the ant which represents the threshold vector is at the same time the chromosome...
The conventional two-dimensional (2-D) entropic thresholding is time consuming due to the exhaustive search in 2-D space. An improved 2-D entropic thresholding method based on ant colony genetic algorithm is proposed. This method extends ant colony genetic algorithm to 2-D discrete space optimization and includes the conventional 2-D entropic thresholding method. In this method, the ant is at the...
