SobelFilter, different results from C and OpenCL Implementations

Hello everyone, I tried to write an OpenCL code to implement the Sobel Filter. But I got strange results. It does detect the edge, but it looks like a distracted version. http://www.alteraforum...

What do you mean by "Then I tried to verfy it in C with the same code (expect for loop, etc.) and got a perfect result" It would help to see what changes you made.

I just want to verify if the code or the algorithm is right. So I write a C code which is almost identical to the kernel, the only differnce is that I added two loops. Then for the result of the C version, it looks perfect. I didn't change the core of the code.
