摘要
提出一种基于网格扩张的视频图像马赛克检测算法,算法以网格扩张的方式遍历图像中的像素,并迅速发现图像中具有相似像素的矩形区域,即马赛克。通过实验表明,该算法在确保较高效率的同时有较高的准确率,满足了视频图像中马赛克检测的功能和性能要求。
This paper presents a mosaic detection algorithm of video image based on grid expansion.The algorithm traverses the image pixels with the way of grid-based expansion,and quickly finds the rectangular area with similar pixels in image,which is the mosaic.The result shows that this algorithm is of high efficiency while ensuring a high accuracy,meeting the functional and performance requirements of mosaic detection of video image.
