IEDGE = VL_QUICKVIS(I, RATIO, KERNELSIZE, MAXDIST, MAXCUTS) creates an edge stability image from a Quickshift segmentation. RATIO controls the tradeoff between color consistency and spatial consistency (See VL_QUICKSEG) and KERNELSIZE controls the bandwidth of the density estimator (See VL_QUICKSEG, VL_QUICKSHIFT). MAXDIST is the maximum distance between neighbors which increase the density.
VL_QUICKVIS takes at most MAXCUTS thresholds less than MAXDIST, forming at most MAXCUTS segmentations. The edges between regions in each of these segmentations are labeled in IEDGE, where the label corresponds to the largest DIST which preserves the edge.
[IEDGE,DISTS] = VL_QUICKVIS(I, RATIO, KERNELSIZE, MAXDIST, MAXCUTS) also returns the DIST thresholds that were chosen.
IEDGE = VL_QUICKVIS(I, RATIO, KERNELSIZE, DISTS) will use the DISTS specified
[IEDGE,DISTS,MAP,GAPS] = VL_QUICKVIS(I, RATIO, KERNELSIZE, MAXDIST, MAXCUTS) also returns the MAP and GAPS from VL_QUICKSHIFT.
