FUNCTIONMSER_create
RETURN TYPEMSER | null
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

delta

it compares (size_{i}-size_{i-delta})/size_{i-delta}

min_area

prune the area which smaller than minArea

max_area

prune the area which bigger than maxArea

max_variation

prune the area have similar size to its children

min_diversity

for color image, trace back to cut off mser with diversity less than min_diversity

max_evolution

for color image, the evolution steps

area_threshold

for color image, the area threshold to cause re-initialize

min_margin

for color image, ignore too small margin

edge_blur_size

for color image, the aperture size for edge blur

Returns

The MSER | null result.
