Groups the object candidate rectangles
[rects, weights] = hog.groupRectangles(rects, weights)
[...] = hog.groupRectangles(..., 'OptionName',optionValue, ...)
Input
- rects Input cell array of rectangles, where each rectangle
is represented as a 4-element vector
{[x,y,w,h], ...}, or a
numeric Nx4/Nx1x4/1xNx4 array.
- weights Input vector of associated weights.
Output
- rects outupt updated rectangles. Includes retained and
grouped rectangles. Grouped rectangles are the average of all
rectangles in that cluster.
- weights output updated weights. Includes weights of
retained and grouped rectangles. Corresponding grouped weights
are the maximum weights of all rectangles in that cluster.
Options
- EPS Relative difference between sides of the rectangles to
merge them into a group. default 0.2
- GroupThreshold Minimum possible number of rectangles in a
group minus 1. The threshold is used on a group of rectangles
to decide whether to retain it or not. If less than or equal
to zero, no grouping is performed. default 1 (i.e only groups
with two or more rectangles are kept).
