Document Type and Number:
Japanese Patent JP6659586
Kind Code:
B2
Abstract:
Provided are methods and devices for coding or decoding an image. The coding method includes that: one coding manner is selected for predictive or matching coding of a current Coding Unit (CU), according to characteristics of pixel samples of the current CU and an adjacent CU of the current CU, from A predetermined predictive coding manners and matching coding manners including at least one predictive coding manner with different prediction characteristics and matching coding manners with mutually different matching characteristics, and the selected coding manner is determined as an optimal coding manner, wherein the A predictive coding manners and matching coding manners include: a predictive coding manner, matching coding manner 1, matching coding manner 2, ...... and matching coding manner A-1, and A is an integer more than or equal to 2; and predictive coding or matching coding is performed on the current CU by adopting the optimal coding manner. By adopting the technical solution, the problem that there is yet no technical solution which can perform high-efficiency coding or high-efficiency decoding for a screen in the related technology is solved, and a coding or decoding process may be rapidly and efficiently implemented.
