跪求 C语言图像分割和边缘检测 程序

clude<stdio.h>

int main()

{

int len=0

int len2=0

FILE* stream

FILE* stream1

FILE* stream2

char buf[50]

char buf1[50]

char buf2[50]

char text[1024]

printf("input anfile path to open:")

scanf("铅滚%s",buf)

stream=fopen(buf,"r+")

fseek(stream,0,SEEK_END)

len=ftell(stream)

printf("the file %s length is %d!\n",buf,len)

len2 = len/2

printf("intput 2 file name: \n")

scanf("%s%s",buf1,buf2)

fseek(stream,0,SEEK_SET)

stream1=fopen(buf1,"w+")

stream2=fopen(buf2,"w+")

fread(text,len2,1,stream)

fwrite(text,len2,1,stream1)

fread(text,len-len2,1,stream)

fwrite(text,len-len2,1,stream2)

fclose(stream)

fclose(stream1)

fclose(stream2)

return 0

}

文件合并

#include<stdio.h>

int main()

{

int len=0

int len2=0

FILE* stream

FILE* stream1

char buf[50]

char buf1[50]

char text[1024]

printf("input anfile path to open:")

scanf("%s",buf)

stream=fopen(buf,"乱激唤r+")

fseek(stream,0,SEEK_END)

printf("哗凯intput another file name: \n")

scanf("%s",buf1)

stream1=fopen(buf1,"r+")

fseek(stream1,0,SEEK_END)

len=ftell(stream1)

fseek(stream1,0,SEEK_SET)

fread(text,len,1,stream1)

fwrite(text,len,1,stream)

fclose(stream)

fclose(stream1)

remove(buf1)//remove the another file

return 0

}

需要在程序目录下有文件存在

这里只仿亩讲原理，不关注速度。实际设计工作中，已经有很多单片机能够识别io端口上升沿和下降沿中断，且方式不止一种。

sbit io_inp=P2^1输入端

bit old_bit输入端电平记备睁森忆

unsigned char low_high上升下降沿标志，0=无变化，1=上升沿，2、下降沿

void io_rest(void)

{

if(old_bit=!io_inp)

{

old_bit=io_inp

if(io_inp=1)

low_high=1

else

low_high=2

}

}

void main(void)

{

old_bit=io_inp=P2^1

while(1)

{

low_high=0

io_rest(void)

//早神在此应用

}

}

C语言太老了吧，你说的C语言是DOS下的C还是WINDOWS下的C，windows下的C语言可以直接调用有差顷前虚清关图像的API实现，就是太麻烦了，DOS下的C好像现在没有乎散人用来写有关图像处理的程序了吧，太老了
