Hello everyone I hope you are well, I wanted to show you the colorization technique I have developed to have a realistic colorization with artificial intelligence algorithms and manual work For the cleaning of this video I used Avisynth and davinci resolve: Avisynth script: SpotLess(RadT=6, ThSAD2=900, pel=4, chroma=true) davinci resolve plugins: automatic dirt removal, dustbuster (Manual work) Artificial intelligence algorithms for colorization: deoldify, Deep Exemplar-based Video Colorization Preparing Reference Images: colorizer pro software (Manual work) Artificial intelligence algorithms for upscale to HD and face restoration RealESRGAN (Integrate GFPGAN to support face enhancement) For Resize Avisynth script: nnedi3_rpow2(cshift="Spline64ResizeMT", rfactor=2, fwidth=960, fheight=720, nsize=4, nns=4, qual=1, etype=0, pscrn=2, threads=0, csresize=true, mpeg2=true, threads_rs=0, logicalCores_rs=true, MaxPhysCore_rs=true, SetAffinity_rs=false, opt=3)
