image2Pixs

public static int[] image2Pixs(java.awt.Image image,
               int iw,
               int ih)

图片转为像素数组

convolImage

public static java.awt.image.BufferedImage convolImage(java.awt.Image image)

过滤 边缘检测 图片

change2Image

public static java.awt.image.BufferedImage change2Image(java.awt.image.BufferedImage image)

变化光度 保持统一.

toBinary

public static byte[] toBinary(int[] pix,
              int iw,
              int ih)

将ARGB图像序列pixels变为2值图像序列im

bin2Rgb

public static int[] bin2Rgb(byte[] bw,
            int iw,
            int ih)

将2值图像字节转为像素

Thinner2

public static byte[] Thinner2(byte[] bm,
              int iw,
              int ih)

连接细化算法

scaleImage

public static java.awt.image.BufferedImage scaleImage(java.awt.image.BufferedImage src,
                                      int width,
                                      int height)

Creates a scaled copy of the source image.

参数:

src - source image to be scaled

width - the width for the new scaled image in pixels

height - the height for the new scaled image in pixels

返回:

a copy of the source image scaled to width x height pixels.
