我有一个java程序的问题,我正在使用sobel运算符进行边缘检测,但是当我尝试使用该函数时,控制台说:
线程"AWT-EventQueue-0"中的异常java.lang.ArrayIndexOutOfBoundsException:262144 at the Obrasek.jButtonSobelActionPerformed的sun.awt.image.ByteInterleavedRaster.getPixels(ByteInterleavedRaster.java:1015)(Obrazek.java:566)
而代码是:
FileInputStream inFile = null;
try {
long beginTime = (new java.util.Date()).getTime();
int i, j;
double Gx[][], Gy[][], G[][];
inFile = new FileInputStream("D://lenacsmall.bmp");
BufferedImage bi = ImageIO.read(inFile);
int width = bi.getWidth();
int height = bi.getHeight();
int[] pixels = new int[width * height];
int[][] output = new int[width][height];
int[] raster = bi.getRaster().getPixels(0,0,width,height,pixels);
int counter = 0;
for(i = 0 ; i < width ; i++ )
{
for(j = 0 ; j < height ; j++ …
