Claim 11:
12. A system for decoding video content, the system comprising: a memory storing a set of instructions; and
one or more processors configured to execute the set of instructions to cause the system to perform operations comprising:
decoding a video bitstream to generate a reconstructed coding block;
applying motion estimation to the reconstructed coding block, to determine a reference block of the reconstructed coding block; and
executing a convolutional neural network (CNN) filter to determine, based on the reference block, a residual associated with the reconstructed coding block, wherein the CNN filter is trained using a training data set comprising:
a motion-compensated training block, and
an un-motion-compensated extended region of the motion compensated training block, the motion-compensated training block being a predicted block based on a motion vector and a reference picture, and the un-motion-compensated extended region comprising unpredicted image data that is not predicted based on the motion vector or reference picture, and wherein the CNN filter comprises a plurality of convolutional layers, each of the plurality of convolutional layers using one or more filter kernels to generate one or more feature maps respectively, and the one or more processors are configured to execute the set of instructions to cause the system to perform operations comprising: extracting, at a first convolutional layer of the CNN filter, spatial features of the reconstructed coding block and the reference block.
