[0021] Such as figure 1 As shown, an image error concealment method includes steps:
[0022] S200: Preliminarily analyze the type of the missing block in the image data to obtain an analysis result of the initial type of the missing block, where the type of the missing block includes a smooth block, a texture block, and an edge block.
[0023] A preliminary analysis of the type of missing blocks in the image data is carried out. Generally, the types of missing blocks include smooth blocks, texture blocks, and edge blocks.
[0024] S400: Use the Hedge algorithm in FPGA to correct the initial type analysis result to determine the type of the missing block.
[0025] FPGA has powerful parallel processing capabilities. Parallel processing capabilities mean that multiple threads can process multiple tasks at the same time. In this step, the Hedge algorithm in FPGA is used for parallel processing, and the type of the lost block is confirmed twice. Using the FPGA parallel processing method, ...
