H.264帧内预测数据用于图像分析的可行性探索

The Feasibility of H.264 Intra Prediction Datas Used into Image Analysis

H.264视频编码中的帧内预测能对当前帧的像素信息进行高精度的预测,从而以极少的残差数据传输图像信息。探索使用H.264编码过程中帧内预测后的数据对当前帧进行快速边缘检测的可行性,并实现帧内预测数据进行边缘检测。最后指出算法的优缺点和需要改进的方面。

The intra prediction process of H. 264 video coding technology predicts the current frame pixel information in high precision. So it can transmit the image information in few data. This paper Explores the possibility method about use intra prediction data in current frame image＇s rapid edge detection, and achieves such edge detection. Finally it points out the advantages and disadvantages of that algorithm.
