In the present paper, architectures implementing fixed block size and variable block size (VBS) motion estimation (ME) algorithms on one bit transformed (1-BT) image frames have been presented. The proposed architectures perform ME by applying diamond search (DS) algorithm on 1-BT image frames. The 1-BT based ME is usually performed by applying full search (FS) algorithm. Our simulation results reveal that the application of DS on 1-BT based ME can significantly reduce the computational complexity which is observed in FS based 1-BT ME at a tolerable degradation in the quality. In terms of latency, the architectures have been shown to be superior to several other 1-BT ME architectures. The presented DS based 1-BT ME architectures have succeeded in reducing the minimum clock frequency required to process a video sequence with a given frame size and frame rate, which in turn reduces the overall power consumption compared with other ME architectures. In particular, for processing SDTV sequences (1280×720 @ 30 fps), the power consumption by the proposed VBS ME architecture is reduced by at least 41% compared to the other 1-BT based ME architectures available in literature. The proposed architectures are therefore, considered suitable for low-power portable video applications typically operated by battery power.
