The implemented Sobel filter algorithm expects each pixel is a 32-bit ARGB integer with
each color as 8-bit depth. A pointer to the ARGB pixel array is provided on a per frame basis.
Output : ZNQ_S32 *rgb_data_out
The implemented algorithm computes each output pixel's value of the frame using the
Sobel filter edge detection algorithm. This function returns a 32-bit edge-detected ARGB
array of the frame with each color as 8-bit depth.
