ImageDev

BlendWithValue

Produces a linear combination between an image and a constant value.

Access to parameter description

The formula applied between the input image $I$ and the constant $C$ is: $$ O(n,m)=\left[\lambda I(n,m)+(100-\lambda)C\right]/100 $$ See also

blendWithValueAlgo.setInputImage( foam );
blendWithValueAlgo.setValue( 4 );
blendWithValueAlgo.setWeight( 60.0 );
blendWithValueAlgo.execute();

std::cout << "outputImage:" << blendWithValueAlgo.outputImage()->toString();
