Video content encoding based on local metrics and parameters
A recently granted patent (Publication Number: US11930168B2) discloses a method for video content encoding that involves calculating local encoding parameters for video blocks based on local metrics, modifying these parameters based on adjacent blocks, and encoding the video content using the adjusted parameters. The local encoding parameters can be quantization or compression parameters, and the local metrics can include factors like target bit rate, texture complexity, contrast, motion indicators, and importance maps. The method also includes spatial and temporal filtering of encoding parameters based on adjacent blocks in the video content, allowing for more efficient and effective video compression.
Furthermore, the patent describes an apparatus and a graphics processing unit implementing the method, where the encoder calculates local encoding parameters, stores parameters for adjacent blocks, and modifies the encoding parameters based on the stored values. The apparatus and graphics processing unit can apply spatial and temporal filtering techniques to enhance the encoding process, responding to scene changes or image characteristics variations. By utilizing transfer functions and filtering methods, the encoding efficiency and quality of the video content can be improved, offering a more sophisticated approach to video compression and encoding in various applications.
