我已经这样做了几天，我似乎无法理解如何找到像素总数。此外，我需要找到图像的中心，这只是坐标的平均值，但每次我放入其中的东西都无法解决。这里是代码到目前为止： import javax.imageio.ImageIO; import java.awt.image.BufferedImage; import java.io. *; import java。*; public class Quiz { static int width，高度; public static void main（String [] args）{ try { BufferedImage image = null; URL url = new URL（imc.kean.edu/cps2231/program6.png）; image = ImageIO.read（url）; height = image.getHeight（）; width = image.getWidth（）; System.out.println（width：+ width +height： +高度）; int [] [] img = new int [height] [width]; for（int y = 0; y< height; y ++）> for（int x = 0; x< width; x ++）> img [ y] [x] = image.getData（）。getSample（x，y，0）; printImg（img）; int color = 2; int cX = 0; int cY = 0; int pixels = 0; for（int Y = 0; Y<高度; Y ++）> for（int x = 0; x< width; x ++）{> if（img [y] [x] == 0）{ label（img， x，y，color）; System.out.println（颜色：+颜色+对象大小：+像素+像素，+居中于+（+ cX +，+ cY +））; color ++; } } } System.out.println（黑色物体总数：+（颜色-2））; printImg（img）; } catch（IOException e）{e.printStackTrace（）; } } static void label（int [] [ ] A，int x，int y，int color）{ if（（x> = 0）&&（y> = 0）&&（x< width）> System.out.printf（ （％d，％d）颜色：％d \ n，x，y，颜色）; A [y] [x] =颜色; 标签（A，x，y-1，颜色）; 标签（A，x-1，y，颜色）; 标签（A，x，y + 1，颜色）; 标签（A，x + 1，y，颜色）; } } static void printImg（int [] [] A）{ for（int y = 0; y< height; y ++）> for（int x = 0; x< width; x ++）> System.out.printf（％d，A [y] [x]）; System.out。 println（）; b $ b } } }
I have been doing this for several days and I cant seem to understand how to find the total number of pixels. Also I need to find the center of the image as well which is just the average of the coordinates but everytime I put something in it doesn't work out. here is code so far: import javax.imageio.ImageIO; import java.awt.image.BufferedImage; import java.io.*; import java.*; public class Quiz { static int width,height; public static void main( String[] args ){ try { BufferedImage image = null; URL url=new URL("imc.kean.edu/cps2231/program6.png"); image = ImageIO.read(url); height=image.getHeight(); width=image.getWidth(); System.out.println("width:"+width+ " height:"+height); int [][] img=new int[height][width]; for (int y=0;y<height;y++)> for (int x=0;x<width;x++)> img[y][x]= image.getData().getSample(x, y, 0); printImg(img); int color=2; int cX=0; int cY=0; int pixels=0; for (int y=0;y<height;y++)> for (int x=0;x<width;x++){> if (img[y][x] ==0){ label(img, x, y, color); System.out.println("Color: " + color + " Object size: " + pixels + " pixels," + " Center at "+"("+cX+","+cY+")"); color++; } } } System.out.println("Total number of black objects:"+ (color-2)); printImg(img); } catch (IOException e) { e.printStackTrace(); } } static void label(int[][] A, int x, int y, int color) { if ((x>=0) && (y>=0) && (x<width)> System.out.printf("(%d,%d) color:%d\n",x,y,color); A[y][x]=color; label(A, x, y-1, color); label(A, x-1,y, color); label(A, x, y+1, color); label(A, x+1, y, color); } } static void printImg(int[][] A) { for (int y=0;y<height;y++)> for (int x=0;x<width;x++)> System.out.printf("%d",A[y][x]); System.out.println(); } } }
推荐答案您应该查看图像的属性以找出宽度和高度。 You should view the properties of the image to find out the width and height.
