Calculated the partial derivates of the image and stored the squares of the derivates plus the product of the dx and dy derivates in secondary images.
Modified the ApplyKernel function to apply only 3x3 kernels on the image. The Sobel function is not useful now, but it will be left as a reference.
Added the order paramenter for the ApplyKernel function. This paramenter defines the order of the kernel to be convolved with the src_img.
Gaussian convolution finished. Only the corner points and some other local maxima are visible on the final image. Must implement a non maxima supression algorithm now.
Implementing the nonmax suppression algorithm.
