In previous ADSTs, DST-7 and DST-4 are used for length 4 and length 8/16/32, respectively. In this LGT experiment we explore transforms between DST-4 and DST-7. When CONFIG_LGT flag is on, adst4 and adst8 are replaced by lgt4 and lgt8, the intermediate transforms with pre-chosen parameters. The LGTs applied here are lgt4_160 and lgt8_170, where the numbers mean the self-loop weights times 100. The associated values for DST-7 and DST-4 are 100 and 200. ovr_psnr: lowres: -0.140 midres: -0.131 hdres: -0.078 These changes are not applied to the highbd scenario in the current version.
