摘要： A method for encoding frames of input video signals, including the following steps: implementing a learning/configuring stage that includes the following steps: providing frames of training video signals; determining training statistical parameters for groups of pixels of the frames of training video signals, and also encoding the frames of training video signals to obtain training modes; configuring a decision tree in response to the training statistical parameters and the training modes; and implementing an operating/encoding stage that includes the following steps: determining operating statistical parameters for groups of pixels of the frames of input video signals, and applying the operating statistical parameters to the configured decision tree to obtain operating modes; and encoding the frames of input video signals using the frames of input video signals and the operating modes.
