基于小波变换的多方向加权聚类颅内肿瘤图像分割方法
INTRACRANIAL TUMOUR IMAGE SEGMENTATION ALGORITHM WITH MULTI-DIRECTIONAL WEIGHTED AGGREGATION BASED ON WAVELET TRANSFORM
摘要
Abstract
Targeted clinical therapy and treatment can be applied in the lesion part after the segmentation is made on MR intracranial tumour area.With clinical practice,we propose a wavelet transform-based intracranial tumour segmentation algorithm with multi-directional weighted aggregation.Through the combination of wavelet transform and multi-directional weighted aggregation algorithm,it enhances the high-frequency signal decomposed with wavelet by using a non-linear compensation image contours,and improves the low-frequency signals by the multi-directional weighted aggregation algorithm with seed point selection.Experimental results show that on the basis of greatly reducing the time complexity,the proposed algorithm can effectively improve the accuracy.关键词
