IMAGE ENCODING/DECODING METHOD AND DEVICE, AND RECORDING MEDIUM IN WHICH BITSTREAM IS STORED - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240015323 titled 'IMAGE ENCODING/DECODING METHOD AND DEVICE, AND RECORDING MEDIUM IN WHICH BITSTREAM IS STORED

Simplified Explanation

The disclosed patent application describes a method for decoding an image using inter and intra prediction techniques. The method involves generating an inter prediction block by predicting the current block based on previous blocks, and generating an intra prediction block by predicting the current block based on its own characteristics. The method also determines weights for the inter and intra prediction blocks and combines them to generate a final prediction block. The intra prediction block is generated using a predefined intra prediction mode.
