Image Processing in ARM

Hello everybody

Could you please F1 Me??!

I want to process an image in Keil using ARM Cortex M-3 (LPC1768). I want to move a window(vector) over my image and compute sth using those pixels in the Window;

The Vector is : [-1 0 1] , Means that minus last and first pixels and put it in the middle.

The compiler doesn’t allow me to access pixels. Also my image is in vector form. I need Sth like this :

For (i=0,i<1240,i++){

Pic(i)=image(i+1)-image(i-10);

}

Before performing such an action also I want to zero pad my image for margins.

But vector Analysis in Keil doesn’t allow me to do such an easy process.

So what( the h… ) should I do ? Please Help me?

implement the C or C++ code on a PC. Get the algorithm correct. Then optimize the coding. Avoid floating point.

Then see if that code is appropriate for a small micro versus, say, a small Linux board or some such.
