Example

std::string path = "D:/dataset/fs/imageFolder/"; std::string result = "D:/dataset/fs/focused.png"; CuviImage gimg = cuvi::io::loadImage(path); const Cuvi32f xScale = 0.5f, yScale = 0.7f; const Cuvi32s newWidth = static_cast<Cuvi32s>(gimg.width() * xScale); const Cuvi32s newHeight = static_cast<Cuvi32s>(gimg.height() * yScale); CuviImage gout(newWidth,newHeight,gimg.type()); //Re-sizing input image to fit output container using bicubic interpolation cuvi::geometryTransforms::resize(gimg,gout, CUVI_INTER_CUBIC);
