PCNN based Otsu multi-threshold segmentation algorithm for noised images 来自 ResearchGate 喜欢 0 阅读量: 37 作者:F Zhou,X. Li,X Zhang 摘要: In this paper, a new image segmentation algorithm based on Otsu thresholding. One of attractive feature of this algorithm is its ability of processing ...
But this multi- threshold Otsu method is of low efficiency and time consuming. Concerning this shortage, this paper made histogram intervals first, and then the rapid dichotomy was used to seek for the threshold in the interval. The improvement in this paper can maintain good segmentation result...
