Abstract: PURPOSE: A method of dividing a video scene on the basis of color and motion characteristics is provided to accurately reflect the meaning of video and reduce scene's excessive division effect. CONSTITUTION: When an MPEG video signal is inputted(S100), the boundary of a shot is detected by using the boundary between a sharp distribution and a gradual distribution of the shot(S200). Color characteristic of the shot is extracted and color similarity of the shot is measured(S300A), and the motion of the shot is extracted and motion similarity is measured(S300B) in order to extract the characteristics of the detected shot. A weighted value is adaptively applied to the similarity between shots with respect to the color and motion(S400A). A scene is divided using the adaptive weighted value and an improved overlapping links technique(S400B). Then, the scene's excessive division effect is compensated(S500).

Abstract translation: 目的：提供基于颜色和运动特性划分视频场景的方法，以准确反映视频的意义，并减少场景的过分分割效果。 构成：当输入MPEG视频信号（S100）时，通过使用锐利分布和拍摄的逐渐分布之间的边界来检测镜头的边界（S200）。 提取拍摄的颜色特征并测量拍摄的颜色相似度（S300A），并且提取拍摄的运动并测量运动相似度（S300B），以便提取检测到的拍摄的特征。 加权值适应于相对于颜色和运动的拍摄之间的相似性（S400A）。 使用自适应加权值和改进的重叠链接技术划分场景（S400B）。 然后，场景的过分除法效果得到补偿（S500）。
