Coding efficiency can be improved by re-aligning pixels of a residual block before transformation to align the pixels of the block with the direction in which the prediction block for the original block was formed. Such an alignment can reduce the number of bits to be included in an encoded bitstream while maintaining the visual quality of the video stream by reducing the amount of structure or texture in the residual block that is not aligned with a horizontal or vertical axis."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adaptive pre-transform scanning patterns for video and image compression","description":"Blocks of a frame of a video stream can be encoded using directional intra prediction modes followed by transforming the residual blocks.
