    • Encoding and decoding a video image having a plurality of frames using a two-step quantization and coding process are disclosed. A block of a frame are encoded by identifying pixels having certain spatial characteristics, forming a second block from the block while replacing the identified pixels with a single pixel value, such as an average of the remaining original pixels. The second block is encoded, such as by transformation and quantization, and placed into a bitstream. The second block is decoded and subtracted from the original block to generate a difference block. The difference block is encoded, such as by quantization, and is placed in the bitstream. At a decoder, both blocks are decoded and combined to reconstruct the original block.

    • Disclosed herein are methods and apparatuses for selective prediction signal filtering. One aspect of the disclosed implementations is a method for encoding a frame of a video stream including determining a first performance measurement for a first set of prediction samples identified for a group of pixels using a first prediction mode, generating a filtered set of prediction samples by applying a filter to a second set of prediction samples, wherein at least one of the filtered set of prediction samples or the second set of prediction samples are identified using a second prediction mode, determining a second performance measurement for the filtered set of prediction samples, generating, using a processor, a residual based on the filtered set of prediction samples and the group of pixels if the second performance measurement exceeds the first performance measurement, and encoding the frame using the residual.
    • 这里公开了用于选择性预测信号滤波的方法和装置。 所公开的实现的一个方面是用于对视频流的帧进行编码的方法,包括使用第一预测模式确定针对一组像素所识别的第一组预测样本的第一性能测量, 将滤波器应用于第二组预测样本,其中使用第二预测模式来识别滤波的预测样本集合或第二组预测样本中的至少一个,确定经滤波的预测样本组的第二性能测量, 如果第二性能测量超过第一性能测量,则使用处理器生成基于滤波的预测样本组和像素组的残差,以及使用残差对帧进行编码。
