Compressing apparatus and method of trained deep artificial neural networks for video coding

摘要

Disclosed is an apparatus for compressing a trained deep artificial neural network for video coding. The compression apparatus according to an embodiment includes a pruning unit for selectively pruning a trained deep neural network of a coding unit constituting video coding, and a quantization for quantizing the trained deep neural network pruned by the pruning unit. And an entropy coding unit for entropy coding the trained deep neural network quantized by the quantization unit and outputting a bitstream. At this time, the pruning unit calculates the value of the elements describing the trained deep neural network, and calculates the value by reflecting the propagation backward through the deep neural network.
