Hybrid Image Thresholding Method using Edge Detection
International Journal of Computer Science and Network Security, 9, 4, 292-299 (2009. 4). PDF


The main disadvantage of traditional global thresholding techniques is that they do not have an ability to exploit information of the characteristics of target images that they threshold. In this paper, we propose a hybrid thresholding method that combines the P-tile method with an edge detector to assist it in the thresholding process. This method successfully generates more accurate object shape extraction than the conventional methods.
