     multiview video coding (mvc) is the process of efficiently compressing stereo (two views) or multiview video signals. the improved compression efficiency achieved by h.264 mvc comes with a significant increase in computational complexity. temporal prediction and inter-view prediction are the most computationally intensive parts of h.264 mvc. therefore, in this paper, we propose novel techniques for reducing the amount of computations performed by temporal and inter-view predictions in h.264 mvc. the proposed techniques reduce the amount of computations performed by temporal and inter-view predictions significantly with very small psnr loss and bit rate increase. we also propose a low energy adaptive h.264 mvc motion estimation hardware for implementing the temporal and inter-view predictions including the proposed computation reduction techniques. the proposed hardware is implemented in verilog hdl and mapped to a xilinx virtex-6 fpga. the fpga implementation is capable of processing 30 × 8 = 240 frames per second (fps) of cif (352 × 288) size eight view video sequence or 30 × 2 = 60 fps of vga (640 × 480) size stereo (two views) video sequence. the proposed techniques reduce the energy consumption of this hardware significantly.
