近來,Chien等人提出了一個有效的預測分水嶺式的視訊切割法。本篇論文提出了一個改良式預測分水嶺的方法來切割影像物件。歸因於從目前的視訊畫面繼承更多的分割結果,我們的改良演算法與Chien等人的方法相比需要較少的計算成本。此外,我們還提供了一個有效的區域融合策略來解決過度切割的問題。最後,我們提出一個新的自動更新方法,基於區域配對累積誤差標準,來中斷錯誤累積的問題。實驗結果顯示本改良方法在計算時間與切割品質的進步。在五組灰階視訊影像序列下,本方法的平均執行時間對應傳統的分水嶺切割法與Chien等人的方法的改良率分別為77.4%和41.8%。
Recently, Chien et al. presented an efficient predictive watershed-based video segmentation algorithm. This thesis presents an improved predictive watershed method for segmenting objects. Due to inheriting more segmentation results from the current frame, our proposed improved method needs less computation e®ort when compared to Chien et al.'s method. In addition, an e±cient region merging strategy is employed to alleviate the over-segmentation problem. Finally, a new efficient automatic renewal scheme, which is based on the integrated error of region-pairs accumulation error criterion, is presented to interrupt the error propagation. Experimental results demonstrate the execution time and quality advantages of our proposed improved algorithm. Under five video sequences, the execution-time improvement ratios of our proposed algorithm over the traditional watershed-based approach and the the previous algorithm by Chien et al. are 77.4% and 41.8%, respectively, in average.
