%0 Journal Article %T Bidirectional Image Thresholding Algorithm Using Combined Edge Detection and P-tile Algorithms %A Taghizadeh, Moslem %A Mahzoun, Mohammad Reza %J Journal of Mathematics and Computer Science %D 2011 %V 2 %N 2 %@ ISSN 2008-949X %F Taghizadeh2011 %X 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 new approach based on combination of modified p-tile and edge detection algorithms to have more accurate object segmentation. Using our proposed method, it is shown that almost all of our experiments resulted to better object segmentation than using traditional methods. %9 journal article %R 10.22436/jmcs.002.02.05 %U http://dx.doi.org/10.22436/jmcs.002.02.05 %P 255--261
