Difference

1 개요

스칼라 또는 이미지와의 Difference 연산을 수행하는 알고리즘입니다. 이미지 픽셀값을 스칼라 또는 대응하는 이미지 픽셀값과의 절댓값 차이를 구하는 연산입니다.

2 알고리즘 상세 설명

Source	Scalar Value : (100)

Difference 알고리즘은 각 채널에 대해 Difference 연산을 수행합니다. 스칼라 연산과 이미지 연산을 지원합니다.

3 파라미터 설정 및 사용 방법

Source 픽셀의 각 채널에 대해 Scalar 연산을 수행할 Scalar 값을 설정합니다.

Scalar 연산

COperationDifference operationDifference;

CFLImage fliSourceImage;
CFLImage fliDestinationImage;

operationDifference.SetSourceImage(fliSourceImage);
operationDifference.SetDestinationImage(fliDestinationImage);
operationDifference.SetOperationSource(EOperationSource_Scalar);
operationDifference.SetScalarValue(mulVarScalar);

operationDifference.Execute();

COperationDifference operationDifference = new COperationDifference();
