* Select low-textured tiles for averaging measurements
* @param min_disparity minimal disparity to accept
* @param max_density maximal trusted tile density (density varies from 0.0 to 1.0)
* @param grow grow selection. When combined with shrink, fills small gaps. Both grow and shrink step
* advances either horizontally or vertically (alternating), so to expand by 1 pixel in all directions
* the value should be set to 2,
* @param shrink shrink selection after expanding to fill small gaps
* @param grow how many layers of tiles should be added after filling gaps and removing small clusters
* @param max_gap_radius maximal radius of a void to be filled
* @param min_clust_radius minimal original cluster radius to survive
* @param density per-tile values of the density of trusted tiles around it.
* @param src_disparity - source disparity array
* @param src_disparity - source disparity array. If null will only use density (that should be > 0)
* @return selection of the low-textured tiles to be processed with averaging correlation (3x3 or 5x5 tiles)
