text: In conclusion to this essay, I find it amazing how Prof. Huang and Prof. Sebe were able to create something as amzaing as this! Jus t being able to read the face of a human is hard for people to do, but now with this new technology, we can do so much! Because a picture, in this case a face, can say a thousand words. And we can add even more words to the statement with the new Facial Action Coding System.The need for these car free suburbs are very imprtant because the more cars that we take off the road the less green house gas fumes are released. Different means of trying to clear the air have been taken,in some countries on certain days people with even numbered licence palts have to leave then other days odd numbers have to leave their cars. So sume places take it very serious people fail to notice that we are killing our planet we have have to do everything possible that we can to save our planet because we won't have another chance to do so.
