670101439f
This patch was based on Yang Xian's intern project code. Further modifications were done. 1. Moved machine-learning related parameters into the context structure. 2. Corrected the calculation of sum_eobs. 3. Removed unused parameters and calculations. 4. Made it work with multiple tiles. 5. Added a speed feature for the machine-learning based partition search early termination. 6. Re-organized the code. The patch was rebased to the top-of-tree. Borg test BDRATE result: 4k set: PSNR: +0.144%; SSIM: +0.043%; hdres set: PSNR: +0.149%; SSIM: +0.269%; midres set: PSNR: +0.127%; SSIM: +0.257%; Average speed gain result: 4k clips: 22%; hd clips: 23%; midres clips: 15%.
