    1717== Implementing the eSSIM metric ^([#hn Andrea Mastroberti])^ ==
    1818The goal was to implement options for the vf_ssim.c filter in libavfilter such that it could compute eSSIM (enhanced SSIM). To do this, I've implemented options for integral images, resizable window size/stride for local statistics and pooling methods to aggregate said statistics (in particular, Minkowski pooling).

     20== x86 assembly code for the VVC decoder ([#hn Stone Chen])^ ==
     21The goal was to implement x86 assembly code for the VVC decoder, focusing on two major functions: the DMVR SAD function and Deblocking. Stone contributed by upstreaming the SAD function, achieving a performance boost of approximately 16-25x. The Deblocking function is nearly complete, with only the Luma long filter remaining. He will continue working on this until it is fully upstreamed, sharing much of the code with HEVC.
