This experiment replaces the 16-point Type-II DCT and 16-point Type-IV DST scaling vp9 transforms with the 16-point orthonormal Daala transforms. These have reduced complexity and are perfect reconstruction. There is currently no net coding performance impact. subset-1: monty-square-baseline-s1-F@2017-07-23T03:43:45.042Z -> monty-square-dct16-s1-F@2017-07-23T03:42:29.805Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 -0.0152 | -0.0028 | -0.0929 | -0.0432 | -0.0457 | -0.0425 | -0.0237 objective-1-fast: monty-square-baseline-o1f-F@2017-07-23T03:44:19.973Z -> monty-square-dct16-o1f-F@2017-07-23T03:43:22.549Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 0.0305 | 0.0926 | -0.1600 | 0.0471 | 0.0219 | -0.0075 | 0.0135 Change-Id: I54fed26d65fd8450693334bb400b1fafd7e0dacb
