RESOURCE-EFFICIENT VIDEO CODING AND MOTION ESTIMATION

Abstract:

In one embodiment, a compute device includes interface circuitry and processing circuitry. The processing circuitry receives, via the interface circuitry, a current frame of a video stream to be encoded. The processing circuitry then determines whether a scene change occurs at the current frame. If a scene change occurs at the current frame, the processing circuitry detects the scene in the current frame by performing pixel segmentation on the current frame. If a scene change does not occur at the current frame, the processing circuitry detects the scene in the current frame by performing motion estimation on the current frame relative to a previous frame in which the scene was detected. Based on the scene detected in the current frame, the processing circuitry then generates one or more encoding parameters and provides those parameters to a video encoder to encode the current frame.
