该程序能通过加标签将模拟表盘得刻度删除掉！通过大量得图片都能得到很好得效果！-through the process of labeling analog dial in the calibration deleted! Through a picture can be a very good result!

将24位表盘图像灰度化和二值化一边中值滤波以便读出指针的角度,change the 24bit graph into 8bit and to two value graph then fiter the graph which is preparing for count the angel degree of the needle .

1、 利用DCT进行jpg压缩，其中DCT可以调用函数，其它尽量自己编写代码，压缩过程可进行适当简化（通过查书了解jpg的原理）； 2、 对图像进行二值化，请利用二值图像压缩方法进行数据压缩，然后解压缩，看通过肉眼能否看清表盘数据，比较两种算法的压缩效果； -1, the use of DCT for jpg compression, which DCT can call the function, the other as far as possible to write your o
