METHOD AND APPARATUS FOR ASYMMETRIC BLENDING OF PREDICTIONS OF PARTITIONED PICTURES - A simplified explanation of the abstract
This abstract first appeared for US patent application 17983017 titled 'METHOD AND APPARATUS FOR ASYMMETRIC BLENDING OF PREDICTIONS OF PARTITIONED PICTURES
Simplified Explanation
- The patent application describes a decoding device that predicts and decodes a picture area of an input image. - The picture area is divided into two parts by a partitioning boundary. - The pixels of each part are predicted using suitable measures. - Blending masks are applied to generate blended regions for the predicted pixels. - The blending masks modify the pixels to generate a complete prediction of the picture area based on both parts. - The blending mask is based on first and second thresholds, which are defined relative to the partitioning boundary. - The first and second thresholds may have different values to create an asymmetrical blending relative to the boundary. - The prediction, combination, and decoding of the picture area are adaptive to the differing contents of the parts within it.
Original Abstract Submitted
A decoding device is provided for decoding of a bitstream, and more specifically for predicting a picture area of an input image for decoding. The picture area has been divided into at least first and second parts by a partitioning boundary, and the pixels of each part are predicted according to suitable measures. Blending masks are then applied to generate blended regions for the predicted pixels, modifying the pixels to generate a complete prediction of the picture area based on both parts. The blending mask is based on first and second thresholds, which are defined relative to the partitioning boundary, and which may have different values to produce an asymmetrical blending relative to the boundary. Based on suitable threshold values, the prediction, combination, and decoding of the picture area is more adaptive to differing contents of the parts therein.
