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

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.

SetScalarValue(CMultiVar<double> mvScalarValue)

4 예제 코드

Scalar 연산

COperationDifference operationDifference;

CFLImage fliSourceImage;
CFLImage fliDestinationImage;
CMultiVar<double> mulVarScalar;

fliSourceImage.Load("../../ExampleImages/OperationDifference/siamesecat3ch.flif");

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

operationDifference.Execute();

COperationDifference operationDifference = new COperationDifference();

CFLImage fliSourceImage = new CFLImage();
CFLImage fliDestinationImage = new CFLImage();
CMultiVar<double> mulVarScalar = new CMultiVar<double>();

fliSourceImage.Load("../../ExampleImages/OperationDifference/siamesecat3ch.flif");

operationDifference.SetSourceImage(ref fliSourceImage);
operationDifference.SetDestinationImage(ref fliDestinationImage);
operationDifference.SetOperationSource(EOperationSource.Scalar);
operationDifference.SetScalarValue(mulVarScalar);

operationDifference.Execute();

Image 연산

COperationDifference operationDifference;

CFLImage fliSourceImage;
CFLImage fliOperandImage;
CFLImage fliDestinationImage;
fliSourceImage.Load("../../ExampleImages/OperationDifference/siamesecat3ch.flif");
fliOperandImage.Load("../../ExampleImages/OperationDifference/space3ch.flif");

operationDifference.SetSourceImage(fliSourceImage);
operationDifference.SetOperandImage(fliOperandImage);
operationDifference.SetDestinationImage(fliDestinationImage);
operationDifference.SetOperationSource(EOperationSource_Image);

operationDifference.Execute();

COperationDifference operationDifference = new COperationDifference();

CFLImage fliSourceImage = new CFLImage();
CFLImage fliOperandImage = new CFLImage();
CFLImage fliDestinationImage = new CFLImage();
fliSourceImage.Load("../../ExampleImages/OperationDifference/siamesecat3ch.flif");
fliOperandImage.Load("../../ExampleImages/OperationDifference/space3ch.flif");

operationDifference.SetSourceImage(ref fliSourceImage);
operationDifference.SetOperandImage(ref fliOperandImage);
operationDifference.SetDestinationImage(ref fliDestinationImage);
operationDifference.SetOperationSource(EOperationSource.Image);

operationDifference.Execute();
