以编程方式使用ImageJ查找边缘 [英] Find Edges with ImageJ Programmatically

问题描述

我想使用 ImageJ 的查找边缘选项，找到edge-found数组并以编程方式将其保存到另一个文件。

I want to use find edges option of the ImageJ, have the edges-found array and save it to another file programatically.

ImagePlus ip1 = IJ.openImage("myimage.jpg");
ImageProcessor ip = new ColorProcessor(ip1.getWidth(), ip1.getHeight());
ip.findEdges();

然而，函数 findEdges 是抽象的，我不能拥有边缘找到的图像。

However, the function findEdges is abstract and I can't have the edge-found image.

编辑：

我写了以下几行：

ip.findEdges();
BufferedImage bimg = ip.getBufferedImage();

然而，当我尝试打印出BufferedImage的RGB值时，它只打印-16777216 对于每个像素RGB。

However, when I try to print out the RGB values of the BufferedImage, it only prints "-16777216" for each pixel RGB.

推荐答案

好的，我得到了解决方案，问题是我没有连接ColorProcessor与图像。

OK, I got the solution, the problem was that I didn't connect the ColorProcessor with the image.

ColorProcessor ip = new ColorProcessor(ImageIO.read(new File("my_image.jpg")));
ip.findEdges();
BufferedImage bimg = ip.getBufferedImage();
