DeinterlaceFrames2d

Separates even and odd frames from an interlaced image.

Access to parameter description

This algorithm generates two output images from an interlaced input image. The first output image contains all even rows of the input image, while the second output image contains its odd rows.

Function Syntax

This function returns a DeinterlaceFrames2dOutput structure containing outputEvenImage and outputOddImage. 
// Output structure of the deinterlaceFrames2d function.
struct DeinterlaceFrames2dOutput
{
    /// The output even field image.
    std::shared_ptr< iolink::ImageView > outputEvenImage;
    /// The output odd field image.
    std::shared_ptr< iolink::ImageView > outputOddImage;
};

// Function prototype
DeinterlaceFrames2dOutput

Parameters

Parameter Name Description Type Supported Values Default Value
input

Object Examples

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

DeinterlaceFrames2d deinterlaceFrames2dAlgo;
deinterlaceFrames2dAlgo.setInputImage( polystyrene );
deinterlaceFrames2dAlgo.setSplitMode( DeinterlaceFrames2d::SplitMode::HALF_IMAGE );
deinterlaceFrames2dAlgo.execute();

std::cout << "outputEvenImage:" << deinterlaceFrames2dAlgo.outputEvenImage()->toString();
std::cout << "outputOddImage:" << deinterlaceFrames2dAlgo.outputOddImage()->toString();

Function Examples

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

auto result = deinterlaceFrames2d( polystyrene, DeinterlaceFrames2d::SplitMode::HALF_IMAGE );

std::cout << "outputEvenImage:" << result.outputEvenImage->toString();
std::cout << "outputOddImage:" << result.outputOddImage->toString();
