ImageDev

DirectionalBlending2d

Combines two images following a direction axis.

Access to parameter description

This algorithm may be very useful in stitching operations in order to manage the overlapping areas.
Remarks: Both input images must have the same dimensions.

Class Syntax

Parameters

Parameter Name Description Type Supported Values Default Value
input
inputImage1
The first input image. Image Binary, Label, Grayscale or Multispectral nullptr
input
inputImage2
The second input image (must have same dimensions and type as the first input). Image Binary, Label, Grayscale or Multispectral nullptr
input
axis
The guiding axis to perform the blending.
X_AXIS The blending is performed along the horizontal axis.
  • The first column of the output image is filled with 100% of the first input image intensities.
  • The last column of the output image is filled with 100% of the second input image intensities.
  • The middle column of the output image is filled with 50% of the first input and 50% of the second input image intensities.
  • Other columns are filled by a linear combination of both input image intensities.
    • Y_AXIS The blending is performed along the vertical axis.
  • The first row of the output image is filled with 100% of the first input image intensities.
  • The last row of the output image is filled with 100% of the second input image intensities.
  • The middle row of the output image is filled with 50% of the first input and 50% of the second input image intensities.
  • Other rows are filled by a linear combination of both input image intensities.
    		• Enumeration X_AXIS
    output
    outputImage
    		The output image. Its dimensions and type are forced to the same values as the inputs. Image nullptr

    Object Examples

    std::shared_ptr< iolink::ImageView > polystyrene = ioformat::readImage( std::string( IMAGEDEVDATA_IMAGES_FOLDER ) + "polystyrene.tif" );

DirectionalBlending2d directionalBlending2dAlgo;
directionalBlending2dAlgo.setInputImage1( polystyrene );
directionalBlending2dAlgo.setInputImage2( polystyrene );
directionalBlending2dAlgo.setAxis( DirectionalBlending2d::Axis::X_AXIS );
directionalBlending2dAlgo.execute();

std::cout << "outputImage:" << directionalBlending2dAlgo.outputImage()->toString();

    Function Examples

    std::shared_ptr< iolink::ImageView > polystyrene = ioformat::readImage( std::string( IMAGEDEVDATA_IMAGES_FOLDER ) + "polystyrene.tif" );

auto result = directionalBlending2d( polystyrene, polystyrene, DirectionalBlending2d::Axis::X_AXIS );

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