ARGUMENTSsrc, threshLow, threshUp
FUNCTIONgapi_inRange
RETURN TYPEGMat
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Applies a range-level threshold to each matrix element.

The function applies range-level thresholding to a single- or multiple-channel matrix. It sets output pixel value to OxFF if the corresponding pixel value of input matrix is in specified range,or 0 otherwise.

Input and output matrices must be CV_8UC1.

Note: Function textual ID is "org.opencv.core.matrixop.inRange"

See: threshold

gapi_inRange(src: GMat, threshLow: GScalar, threshUp: GScalar): GMat;
src

input matrix (CV_8UC1).

threshLow

lower boundary value.

threshUp

upper boundary value.

Returns

The GMat result. Release returned native handles with using or delete(), including handles nested in results.
