Processing

The image processing is done in three steps

1. Crop the image to have a 160 x 144 ratio
2. Reduce the image to a planar2 grayscale ie each pixel holds 2 bits which is 4 colors. Here we also need to dither which is build into the Accelerate Framework
3. Iterate through each pixel and map the gray value to a green value
