Scaled Multiply

1 개요

이미지 혹은 Scalar 값을 사용하여 Scaled Multiply 연산을 수행하는 알고리즘입니다.

2 알고리즘 상세 설명

Scaled Multiply의 연산은 다음 식을 활용합니다.

I_{Dst}(x,y) = (I_{Src}(x,y) * I_{Opr}(x,y)) / I_{Max}

Max값은 이미지 타입의 최댓값을 뜻하며, float 혹은 double인 경우 MAX를 1로 설정하여 일반적인 곱셈 연산을 수행합니다.

Scalar 연산

COperationScaledMultiply scaledMultiply;

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

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

scaledMultiply.Execute();

COperationScaledMultiply scaledMultiply = new COperationScaledMultiply();

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

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

scaledMultiply.Execute();

Image 연산

COperationScaledMultiply scaledMultiply;

CFLImage fliSourceImage;
CFLImage fliOperandImage;
CFLImage fliDestinationImage;

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

scaledMultiply.Execute();

COperationScaledMultiply scaledMultiply = new COperationScaledMultiply();

CFLImage fliSourceImage = new CFLImage();
CFLImage fliOperandImage = new CFLImage();
CFLImage fliDestinationImage = new CFLImage();

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

scaledMultiply.Execute();
