From 06b42925348ff4857eb38d5010285d41256eec75 Mon Sep 17 00:00:00 2001 From: Pierre-Emmanuel Viel Date: Sat, 16 May 2020 20:13:00 +0200 Subject: [PATCH] Fix: error in the dimension used for computeMinMax Instead of using the current dimension for which we just got a big span, we were computing Min and Max for the previous dimension stored in cutfeat (and using 0 instead of the dimension indice for the very first dimension with "span > (1-eps)max_span") --- modules/flann/include/opencv2/flann/kdtree_single_index.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/modules/flann/include/opencv2/flann/kdtree_single_index.h b/modules/flann/include/opencv2/flann/kdtree_single_index.h index fa38f9f1a2..e64848cb04 100644 --- a/modules/flann/include/opencv2/flann/kdtree_single_index.h +++ b/modules/flann/include/opencv2/flann/kdtree_single_index.h @@ -461,7 +461,7 @@ private: DistanceType span = bbox[i].high-bbox[i].low; if (span>(DistanceType)((1-EPS)*max_span)) { ElementType min_elem, max_elem; - computeMinMax(ind, count, cutfeat, min_elem, max_elem); + computeMinMax(ind, count, (int)i, min_elem, max_elem); DistanceType spread = (DistanceType)(max_elem-min_elem); if (spread>max_spread) { cutfeat = (int)i;
