视频图像的边缘检测与边缘细化

Edge Detection and Edge Thinning of Video Sequences

在有效滤除原始视频图像噪声的基础上 ,首先对视频图像进行边缘提取得到单边缘图像 ,然后再对得到的单边缘图像进行边缘提取 ,得到双边缘图像 ,最后将前两次得到的边缘图像进行差分 ,得到较为理想细化边缘图像。若结果仍不能满足特殊需要 ,可重复上述方法 ,直到得到理想边缘。实验结果表明 ,该方法在提取视频图像的细化边缘方面有明显的效果。

Based on filtering of original video noise, firstly, we detected edge of filtered image and got single edge image. Then, we detected edge of single edge image and got double edge image. Finally, we got different image of single edge image and double edge image and got ideal thinner edge image. If this result could not meet special need, we could use this method repeatedly. Experiments proved that the method is good for edge thinning of video sequences.
