Java imageJ如何获得像素rgb值？

Java imageJ如何获得像素rgb值？,java,imagej,Java,Imagej,我有一个保存多边形坐标的简单插件： Roi roi = imp.getRoi(); Polygon p = roi.getPolygon(); for (int i = 1; i <= p.npoints; i++) { // létrehozzuk az onvif féle vector-t org.onvif.ver10.schema.Vector myVector = new Vector(); myVector.setX((float) p.xpoints[i - 1]); my

我有一个保存多边形坐标的简单插件：

Roi roi = imp.getRoi();
Polygon p = roi.getPolygon();
for (int i = 1; i <= p.npoints; i++) {
// létrehozzuk az onvif féle vector-t
org.onvif.ver10.schema.Vector myVector = new Vector();
myVector.setX((float) p.xpoints[i - 1]);
myVector.setY((float) p.ypoints[i - 1]);
op.getPoint().add(myVector);
// IJ.log("Vector X Elements " + i + " :" + MyVector.getX());

        }

Roi=imp.getRoi（）；
多边形p=roi.getPolygon（）；
对于（int i=1；i
int[]r；

对于（int i=1；i假设图像为32位RGB：


ImagePlus im = IJ.getImage();
ImageProcessor imp = im.getProcessor();

int[] rgb = new int[3];
imp.getPixel(X,Y,rgb);

IJ.log(Arrays.toString(rgb));



CT图像的HU值呢

ImagePlus im = IJ.getImage();
ImageProcessor imp = im.getProcessor();

int[] rgb = new int[3];
imp.getPixel(X,Y,rgb);

IJ.log(Arrays.toString(rgb));
