ImageDev

InvertImage

Calculates the reverse intensities of an image on a given number of significant bits.

Access to parameter description

InvertImage calculates the reverse of an image. The algorithm works in two steps: Remark: Applying InvertImage on all the bits of an image gives the same result as applying LogicalNot.

Object Examples

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

InvertImage invertImageAlgo;
invertImageAlgo.setInputImage( foam );
invertImageAlgo.setSignificantBitNumber( 8 );
invertImageAlgo.execute();

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

foam = imagedev.read_vip_image(imagedev_data.get_image_path("foam.vip"))

invert_image_algo = imagedev.InvertImage()
invert_image_algo.input_image = foam
invert_image_algo.significant_bit_number = 8
invert_image_algo.execute()

print( "output_image:", str( invert_image_algo.output_image ) )

ImageView foam = Data.ReadVipImage( @"Data/images/foam.vip" );

InvertImage invertImageAlgo = new InvertImage
{
    inputImage = foam,
    significantBitNumber = 8
};
invertImageAlgo.Execute();

Console.WriteLine( "outputImage:" + invertImageAlgo.outputImage.ToString() );

Function Examples

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

auto result = invertImage( foam, 8 );

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

foam = imagedev.read_vip_image(imagedev_data.get_image_path("foam.vip"))

result = imagedev.invert_image( foam, 8 )

print( "output_image:", str( result ) )

ImageView foam = Data.ReadVipImage( @"Data/images/foam.vip" );

IOLink.ImageView result = Processing.InvertImage( foam, 8 );

Console.WriteLine( "outputImage:" + result.ToString() );
