This paper proposes a novel algorithm for adaptive image segmentation  it can be applied in many conditions  based on thresholding technique and segments merging according to their characteristics combine with spatial position. Our earlier work of getting the entire information of the histogram could help choose the multiple thresholds. However  including complex target segmented. We describe the algorithm in detail and perform simulation experiments. The computation based on pixels can fully parallel processing to save time. 2006 IEEE.  not all the peaks of the histogram correspond to obvious structural unit in the image. Spatial information must be involved. This paper also suggests subjoining segments matching for video image tracking. They will give great help to image segmentation. The proposed algorithm can meet the real-time requirement and lead to higher segmentation accuracy  some types of texture can also be segmented well   Improved temporal clustering analysis method for detecting multiple response peaks in fMRI 期刊论文  OAI收割 JOURNAL OF MAGNETIC RESONANCE IMAGING, 2006, 卷号: 23, 期号: 3, 页码: #REF! 作者:  Lu N(鲁娜);  Dan BC(单保慈);  Li K(李可);  Yan B(闫镔);  Wang W(王伟) 收藏  |  浏览/下载：28/0  |  提交时间：2016/04/13 fMRI  data analysis  temporal clustering analysis (TCA)  multiple active peaks  ETCA
