Original Abstract Submitted
A video encoding system is configured to determine, based on image data, a distortion metric for a prediction mode candidate based on 1) gradient similarity between a prediction block of the image data and a reconstructed prediction block of reconstructed image data generated based on the image data and 2) motion between two frames of the image data. The video encoding system is also configured to select, from a plurality of prediction mode candidates, the prediction mode candidate as a prediction mode based at least in part on the distortion metric. Additionally, the video encoding system is configured to encode the image data based on the prediction mode.
