基于視頻對象的區(qū)域分割及其應用

為適應MPEG-4 基于對象的應用，提出一種基于視頻對象的區(qū)域分割算法。在視頻對象的指導下，利用均值漂移進行分割，性能
比傳統(tǒng)均值漂移算法在計算時間、占用內存等方面均有提高，適用于運算速度要求高和處理器資源有限的情況。將分割結果應用于區(qū)域指
導的圖像插值，能保證較快的處理速度和興趣區(qū)域較好的圖像質量。實驗結果證明了該方法的有效性。
關鍵詞：區(qū)域分割；均值漂移；圖像插值

【Abstract】In order to adapt to the requirement of MPEG-4 object-oriented operations, Region Segmentation based on Video Object (RSVO) is
proposed. The mean shift process can be performed in the area of video object. RSVO can speed up calculating time and save memory compared
with traditional mean shift method, and it is suitable for situation where high speed is needed and memory resource is restricted. In order to save
calculating time while guarantee high quality for the region of interest, results of RSVO are used to area-directed image interpolation. Experimental
results show the validity of the method.
【Key words】region segmentation; mean shift; image interpolation
