This article mainly explains the "JAVA graying and binary picture method is what", the article explains the content is simple and clear, easy to learn and understand, the following please follow the editor's ideas slowly in-depth, together to study and learn "JAVA graying and binary picture method is what" it!

Package image; import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; import javax.imageio.ImageIO; public class ImageDemo {public void binaryImage () throws IOException {File file = new File (System.getProperty ("user.dir") + "/ src/2722425974762424026.jpg"); BufferedImage image = ImageIO.read (file); int width = image.getWidth (); int height = image.getHeight () BufferedImage grayImage = new BufferedImage (width, height, BufferedImage.TYPE_BYTE_BINARY); for (int I = 0; I

< width ; i++){ for(int j = 0 ; j < height; j++){ int rgb = image.getRGB(i, j); grayImage.setRGB(i, j, rgb); } } File newFile = new File(System.getProperty("user.dir")+"/src/2722425974762424028.jpg"); ImageIO.write(grayImage, "jpg", newFile); } public void grayImage() throws IOException{ File file = new File(System.getProperty("user.dir")+"/src/2722425974762424026.jpg"); BufferedImage image = ImageIO.read(file); int width = image.getWidth(); int height = image.getHeight(); BufferedImage grayImage = new BufferedImage(width, height, BufferedImage.TYPE_BYTE_GRAY); for(int i= 0 ; i < width ; i++){ for(int j = 0 ; j < height; j++){ int rgb = image.getRGB(i, j); grayImage.setRGB(i, j, rgb); } } File newFile = new File(System.getProperty("user.dir")+"/src/2722425974762424027.jpg"); ImageIO.write(grayImage, "jpg", newFile); } public static void main(String[] args) throws IOException { ImageDemo demo = new ImageDemo(); demo.binaryImage(); demo.grayImage(); } } 主要就是BufferedImage.TYPE.BYTE.GRAY灰度化，BufferedImage.TYPE.BYTE.BINARY二值化 原图：
