Digital Imagery

Digital imagery is one of those things that I've heard of before but never really had tons of knowledge about. This article taught me a lot about the history and uses of digital imagery. Digital image processing was developed in the 1960's at a few differet places including, MIT, the University of Maryland, and etc. At this time the cost of digital image processing was high due to the expensive computers in that era. However, as time went on, computers became more and more cost friendly, making digital image processing more and more affordable. Digital image processing is now the most common used form of image processing because it is the mose versitile as well as the cheapest. Digital image processing is practical technology for classification, feature extraction, pattern recognition, projection, and multi-scale signal analysis. Some techniques used for digital image processing include, self-organizing maps, hidden markov models, and independent component analysis.
I think that digital imagery could be useful in teaching and education in many ways. For example, children of all ages love to take pictures. My five year old cousin even has a fisher price kids digital camera that allows her to store twenty five pictures on it at one time. You could apply this technology in a classroom by possibly having kids take photos of things shaped differently such as stop signs (0ctagon) or a picture frame (square/rectangle) rather than just drawing them when they are taking a lesson on different shapes. Also, art class teachers could use digital imagery by taking a photo of something and having their students draw a replica of it.
I think that this article was very informative and I enjoyed reading it. It taught me a lot about digital image processing from its history to what can be done with it today. I learned that today, digital image processing is the cheapest form of image processing as well as the cheapest and most versitile. I use it in my everyday life when I use my digital camera and someday I will probably use it in my teaching career as well. I would like to further research digital imagery because although this article was good I do think that there is more to be learned about this specific technology. I would like to read another article explaining more about the technical aspects of digital imagery.
