my project is about median filtering a grey image using dsp processor C6713 and the simulator is CCS v3.....the problem i'm facing is that the processor is unable to read the image...may be there is a requirement for header file of the image that must be included in windows....i have attached my c code so please go through and solve my problem.
below my c file
#include<stdio.h>
#include<stdlib.h>
#include<alloc.h>
#define M 480
#define N 480
main()
{

int **image,**image1;
image=(int**)calloc(N,sizeof(int));
image1=(int**)calloc(N+2,sizeof(int));
for(i=0;i<N;i++)
{
image[i]=(int*)calloc(M,sizeof(int));
}
for(i=0;i<N+2;i++)
{
image1[i]=(int*)calloc(M+2,sizeof(int));
}
fs=fopen("Image225.pnm","r");
if(fs==NULL)
{
puts("can not open the source file");
exit(0);
}
ft=fopen("newcar1.pnm","w");
for(i=0;i<N;i++)
for(j=0;j<M;j++)
{
fscanf(fs,"%d\n",&image[i][j]);
//printf("%d\n",image[i][j]);
}
fclose(fs);
for(i=0;i<N+2;i++)
for(j=0;j<M+2;j++)
{
image1[i][j]=0;
}

}
//replace the element with the median value i.e. the 4th value
/*for(i=0;i<9;i++)

getchar();
}

}
