[英]Wavelet Transform (Haar or Daubechies) in Java with BoofCV
Does anybody knows how to use a wavelet transform (Haar or Daubechies) of BoofCV in Java? 有人知道如何在Java中使用BoofCV的小波变换(Haar或Daubechies)吗?
There's no code example on the web and I'm very new at this library. 网上没有代码示例,我在这个库中是新手。
I've tried this code below, but so for no results. 我已经在下面尝试过此代码,但是没有结果。
public static void main(String[] args) throws IOException, InstantiationException, IllegalAccessException {
String dir = "C:\\Users\\user\\Desktop\\ImgTest\\";
BufferedImage buff =UtilImageIO.loadImage(dir+"img.png");
ImageUInt16 aux = UtilImageIO.loadImage(dir+"img.png", ImageUInt16.class);
ImageSInt16 input = new ImageSInt16(aux.width, aux.height);
input =ConvertImage.convert(aux, input);
ImageSInt32 output = new ImageSInt32(aux.width, aux.height);
int minPixelValue = 0;
int maxPixelValue = 255;
WaveletTransform<ImageSInt16, ImageSInt32, WlCoef_I32> transform =
FactoryWaveletTransform.create_I(FactoryWaveletHaar.generate(true, 0), 1,
minPixelValue, maxPixelValue,ImageSInt16.class);
output=transform.transform(input, output);
//BufferedImage out = ConvertBufferedImage.convertTo(output, null);
BufferedImage out = new BufferedImage(input.width*6, input.height*6, 5);
out = VisualizeBinaryData.renderLabeled(output, 0, out);
ImageIO.write(out, "PNG", new File(dir+"out.png"));
}
}
I also tried JWave, but there's no code example either and the responsible wasn't able to help with it. 我也尝试过JWave,但是也没有代码示例,负责人也无法提供帮助。
Thank you! 谢谢!
