Abstract:
An encoder and a video processing system including the encoder are provided. The encoder may include a quantization operation selection circuit configured to generate first data by performing a first quantization operation based on input data including image data of a frequency domain, to generate a feature value based on the first data, and to generate a control signal for selecting a second quantization operation or a rate-distortion optimized quantization (RDOQ) operation based on a machine learning model trained based on training data that includes the feature value. Additionally, the encoder may include a quantizer configured to perform the second quantization operation or the RDOQ operation based on the control signal and to generate output data (e.g., after performing the second quantization operation or the RDOQ operation).
Abstract:
A transform processor may process original data that includes video information by using at least one of first and second processing methods, and generates at least one of first and second transformed data. Index determination logic may determine an index satisfying a determination condition based on at least one of the first and second transformed data. Energy compaction determination logic may determine energy compaction of at least one of the first and second transformed data based on the determined index. Output selection logic may selectively output one of the first and second transformed data based on the determined energy compaction. An entropy encoder may encode data output from the output selection logic.
