提出了使用快速帧内预测算法，通过应用Sobel算子来产生边界映射，形成了一个包含方向和幅度的边界向量。对预测区域内的像素点的边界映射的幅度值进行了直方图化。提出了基于直方图统计的快速帧内预测模式选择方式。测试结果表明，通过使用边界方向直方图算法，在进行率失真模式选择时，大大降低了所需要进行的帧内预测的种类。

The prediction algorithm for fast intra use, through the application of Sobel operator to generate the boundary mapping, form a contains boundary vector direction and magnitude. The boundary pixels in the forecast area mapping of the amplitude values of the histogram equalization. Presents a fast frame histogram statistics of intra prediction mode selection method based on. The test results show that, by using the edge direction histogram algorithm, the rate distortion model, greatly reducing the types required for intra prediction.
