Extermal 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 iself 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 are of the extremal region and VlMserExtrReg::area_top is the area of the extremal region containing this region in the level set of intenisty VlMserExtrReg::area + delta
.
VlMserExtrReg::variation is the relative area variation (area_top-area)/area.
VlMserExtrReg::max_stable is a flag signaling wether this extremal region is also maximally stable.
index of the parent region
index of pivot pixel
value of pivot pixel
shortcut used when building a tree
