Second , some popular spatial and temporal technology about the vop segmentation were introduced . third , a modified watershed segmentation preprocessed by multi - scale morphological filters and post processed with improved fast region merging methods was proposed to obtain a good spatial segmentation 在第三章中,介紹了分水嶺變換的定義、優(yōu)缺點,并研究了在傳統(tǒng)分水嶺的基礎(chǔ)上利用數(shù)學(xué)形態(tài)學(xué)濾波器緩解算法中過分割現(xiàn)象的改進(jìn)算法,并給出一種能獲取全局最優(yōu)解的區(qū)域合并方法。
