AbsoluteValue

Computes the absolute value of an image.

Access to parameter description

The AbsoluteValue algorithm computes the absolute value of the grayscale values within an image I.
The formula is: O(n,m)=|I(n,m)| See also

Function Syntax

This function returns outputImage. 
// Function prototype
std::shared_ptr< iolink::ImageView >
absoluteValue( std::shared_ptr< iolink::ImageView > inputImage, std::shared_ptr< iolink::ImageView > outputImage = NULL );

Class Syntax

Parameters

Parameter Name Description Type Supported Values Default Value
input
inputImage
The input image. Image Binary, Label, Grayscale or Multispectral nullptr
output
outputImage
The output image, size is the same values as the input. Image nullptr

Object Examples

auto foam = readVipImage( std::string( IMAGEDEVDATA_IMAGES_FOLDER ) + "foam.vip" );

AbsoluteValue absoluteValueAlgo;
absoluteValueAlgo.setInputImage( foam );
absoluteValueAlgo.execute();

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

Function Examples

auto foam = readVipImage( std::string( IMAGEDEVDATA_IMAGES_FOLDER ) + "foam.vip" );

auto result = absoluteValue( foam );

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