Blending

• There are a range of simple techniques that can be used in early vision, late vision and beyond.
• Blending is one such technique.
• You can take a bunch of pixels, and sum those around it.
• So, a pixel might have a value between 0 and 9 depending on the value of those around it on the input.
• This can be use to spread out the data so there can be better categorisation.
• This can also be useful for removing minor problems in the image.
