ADAPTIVE FILTER INTRA PREDICTION MODES IN IMAGE/VIDEO COMPRESSION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240267514 titled 'ADAPTIVE FILTER INTRA PREDICTION MODES IN IMAGE/VIDEO COMPRESSION
Simplified Explanation:
The patent application describes a method for decoding a compressed bitstream by identifying an adaptive intra-prediction mode based on neighboring pixel locations and training regions. Filter coefficients are determined to minimize differences between pixels in the training region and their predictions, which are used to generate a prediction block for the block being decoded.

Original Abstract Submitted
a compressed bitstream is configured for decoding by operations that include identifying an adaptive intra-prediction mode indicative of at least a training region or a configuration of neighboring pixel locations. the training region neighbors a block and consists of reconstructed pixels. filter coefficients used to obtain respective prediction pixels of neighboring pixels within the training region when applied according to the configuration of the neighboring pixels are determined. the filter coefficients minimize a function of differences. each difference is a respective difference between a pixel in the training region and a prediction of that pixel in the training region. a prediction block is generated for the block by recursive extrapolations that use the filter coefficients by predicting each pixel of the prediction block by applying the filter coefficients to the configuration of neighboring pixels for the pixel being predicted.
