ARGUMENTSsrc1, src2, mask
FUNCTIONgapi_select
RETURN TYPEGMat
Call structure. A void return can still write to destination arguments. The parameter descriptions define inputs, outputs and ownership.

Select values from either first or second of input matrices by given mask. The function set to the output matrix either the value from the first input matrix if corresponding value of mask matrix is 255, or value from the second input matrix (if value of mask matrix set to 0).

Input mask matrix must be of CV_8UC1 type, two other inout matrices and output matrix should be of the same type. The size should be the same for all input and output matrices. Supported input matrix data types are CV_8UC1, CV_8UC3, CV_16UC1, CV_16SC1, CV_32FC1.

Note: Function textual ID is "org.opencv.core.pixelwise.select"

gapi_select(src1: GMat, src2: GMat, mask: GMat): GMat;
src1

first input matrix.

src2

second input matrix.

mask

mask input matrix.

Returns

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