Run-time comparison of the encoder for the proposed system with the H.264 (intra) method as well as the DISCOVER codec. All results are in milliseconds per frame. Only WZ frames were considered for the DISCOVER codec and the proposed system. ‘Disc’ refers to the DISCOVER codec and ‘Prop’ refers to the proposed codec.
