چکیده

Image Segmentation is one of the most important techniques in graphic and image processing. Most of image segmentation methods are based on clustering algorithms. Dataclustering is an unsupervised classification technique and belongs to NP-hard problems. One of the methods for solvingNP-hard problems is applying swarm intelligence algorithms. Artificial fish swarm algorithm (AFSA) is one of the swarm intelligence algorithms which is working based on populationand random search. In this paper, a new cooperative algorithm based on AFSA and k-means is proposed for performing imagesegmentation based on multi-level thresholding. The proposed algorithm utilizes both global search ability of AFSA and localsearch ability of k-means. The proposed algorithm along with some other known algorithms has been applied for segmenting famous images and their efficiency has been compared with each other. Experimental results comparison shows acceptable efficiency of the proposed algorithm.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
