[Summary] PatchTable: Efficient Patch Queries for Large Datasets and Applications

August 10, 2017 starea

Dr. Connelly Barnes have led the research on patch-based algorithms over the years. Some of his most famous patch-based research are: PatchMatch (SIGGRAPH 2009, EECV 2010, CAF) Image Melding (SIGGRAPH 2012) Patch-based HDR video (SIGGRAPH Asia 2013) Synthesis of Complex (SIGGRAPH 2015) PatchTable (SIGGRAPH 2015) Artistic Media Digital Bas-Relief (SIGGRAPH 2007) RealBrush (SIGGRAPH 2013) DecoBrush…

void mainImage( out vec4 O, vec2 u )
{
    vec2 R = iResolution.xy, 
         M = iMouse.xy / R,
         S = ( M.y < 1e-3 ? 6.
                          : mix(3., 5.5, M.x/M.y) ) / R;
      
    O = vec4( length( M= mod( u/R, S) - S*.5 ) <
               dot( texture(iChannel0, u/R - M),  vec4( .21, .72, .07, 0) ) *
                S.x * ( 1. + .3 * sin(iTime) ) );
