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. Grouped rectangles are the average of all rectangles in that cluster.
• weights output updated weights. 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).
