import { gapi_absDiffC } from '@banou/opencv-wasm'

Use after await initOpenCV(). See the initialization and named imports guide.

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

Calculates absolute value of matrix elements.

The function abs calculates absolute difference between matrix elements and given scalar value:

\texttt{dst}(I) =  \texttt{saturate} (| \texttt{src1}(I) -  \texttt{matC}(I)|)

where matC is constructed from given scalar c and has the same sizes and depth as input matrix src.

Output matrix must be of the same size and depth as src.

Supported matrix data types are CV_8UC1, CV_8UC3, CV_16UC1, CV_16SC1, CV_32FC1.

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

See: min, max

gapi_absDiffC(src: GMat, c: GScalar): GMat;
src

input matrix.

c

scalar to be subtracted.

Returns

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