Description

There is an off-by-one error in the Brief descriptor. When a keypoint lies at a specific distance from the border, it is not removed by DescriptorExtractor::removeBorderKeypoints(), but later causes an off-by-one error (and assertion in debug build) in smoothedSum().

The attached patch solves this simply by expanding the border by one pixel.
