Higher Level Visual Processing

Higher Level Visual Processing

 I hope that after this lesson you will never take your brain and mind’s amazing ability to recognize objects and process vision for granted again. We all take it for granted because almost all of the processing is occurring in the unconscious part of our mind. Doing this work in the unconscious allows us to do parallel processing which means that we can do a bunch of different types or pathways of processing at the same time. This is necessary for us to recognize objects in real time. One of the reasons that scientists have realized how amazing our object recognition skills are has to do with trying to make computers that can do the same thing. Watch this 4 minute lecture from an artificial intelligence course about why object recognition is so hard. Remember that brains are also using the intensity and color of light detected by individual photoreceptors, and somehow putting it together and recognizing objects.
