ARGUMENTSinput, output, r1, s1
FUNCTIONintensity_transform_contrastStretching
RETURN TYPEvoid
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Given an input bgr or grayscale image, apply linear contrast stretching on domain [0, 255] and return the resulting image.

intensity_transform_contrastStretching(input: Mat, output: Mat, r1: number, s1: number, r2: number, s2: number): void;
input

input bgr or grayscale image.

output

resulting image of contrast stretching.

r1

x coordinate of first point (r1, s1) in the transformation function.

s1

y coordinate of first point (r1, s1) in the transformation function.

r2

x coordinate of second point (r2, s2) in the transformation function.

s2

y coordinate of second point (r2, s2) in the transformation function.
