    Improve skip_txfm thresholds in the non-rd mode selection · 81fc5bf8
    Yunqing Wang authored
    Modified the thresholds of deciding whether or not to skip
    the transforms in model_rd_for_sb_y(). Used zbin[] instead
    of dequant[] to be more precise. Also, modified the checking
    coditions.
    
    Rtc set borg test results (at speed 6) showed:
    average PSNR gain: 0.138%, overall PSNR gain: 0.158%,
    and SSIM gain: 0.177%.
    
    The data rate test was modified slightly as suggested by
    Marco.
