Detailed Description
MSER: extremal region.
Extremal regions (ER) are extracted from the region forest. Each region is represented by an instance of this structure. The structures are stored into an array, in arbitrary order.
ER are arranged into a tree. parent points to the parent ER, or to itself if the ER is the root.
An instance of the structure represents the extremal region of the level set of intensity VlMserExtrReg::value and containing the pixel VlMserExtReg::index.
VlMserExtrReg::area is the area of the extremal region and VlMserExtrReg::area_top is the area of the extremal region containing this region in the level set of intensity VlMserExtrReg::area + delta.
VlMserExtrReg::variation is the relative area variation (area_top-area)/area.
VlMserExtrReg::max_stable is a flag signaling whether this extremal region is also maximally stable.
