motion block meaning in English

动块

Examples

  1. Following are detailed steps of this system : in the segmentation section , we use three successive frames to detect the motion infomation of the pictures , by using blockmatching algorithm in two successive frames twice , we can get two pictures composed of motion blocks of the moving object , then we find out the common motion blocks of the two pictures , experiments prove these blocks approximately compose the moving object . after getting the motion blocks , we calculate the center of these blocks as the center of the moving object , thus we can use the center point as the origin , construct n straight linesjoining the boundry of the image and the center . on each line , we can find out a proper point near the object contour according to some criteria , then we use these n points as the initial points of the snake and let the snake converge on the object contour , thus finish the segmentation of the moving object
    本方案的实现过程为:分割部分:对运动目标的前后三帧进行两次块匹配运动检测,通过找出两个匹配结果中运动图像块的公共部分,获得组成运动目标的图像块;求出运动目标图像块的形心作为运动目标的中心,以此中心为端点,向四周发散出角度间隔为的n条射线,射线的另一端终止于图像的边缘;在每条射线上按照一定的准则(点的梯度和与目标中心的距离在一定阈值范围内)找出n个初始轮廓点;以这些初始轮廓点作为主动轮廓模型( snake )的初始点,用改进的贪婪算法使snake收敛到待分割的运动目标轮廓上。
