Example
//Creating input images
CuviImage input = cuvi:io::loadImage(path);
//Create output image of same size but different type
CuviImage output(input.size(), CUVI_DEPTH_32F, input.channels());
//Convert image by normalizing pixel values (divide each pixel by 255)
cuvi::dataExchange::convertScale(input, output, 1.0f/255.0f); |
