The FPGA can see!

The camera is an OV7670 which has a 600x800 resolution. The image stored on the FPGA has been reduced down to 1/4 size and only 3bits per pixel. This was done to reduce memory. The aspect ratio on the photo is off. That was due to the use of a memory block with power of 2 size. When the aspect ratio was fixed, there is unused memory which I plan to have region of interest (ROI) where I will place a cropped full 1x size region. This will allow effective pattern identification and also high resolution position tracking.
