Computer imaging

It is a fascinating and exciting area to be involved today. Visual information, transmitted in the form of digital image, is becoming a major method of communication in the modern age. Computer imaging Can be defined a acquisition and processing of visual information by computer. The importance of computer imaging is derived from the fact that our primary sense is our visual sense, and the information that be conveyed in images has been known throughout the centuries to be extraordinary (one picture is worth a thousand words). Computer representation of an image requires the equivalent of many thousands of words of data, so the massive amount of data required for image is a primary reason for the development of many sub areas with field of computer imaging, such as image compression and segmentation .Another important aspect of computer imaging involves the ultimate “receiver” of visual information in some case the human visual system and in some cases the human visual system and in others the computer itself.
Computer imaging can be separate into two primary categories:
1. Computer Vision.
2. Image Processing. In computer vision application the processed images output for use by a computer, whereas in image processing applications the output images are for human consumption.
These two categories are not totally separate and distinct. The boundaries
that separate the two are fuzzy, but this definition allows us to explore the
differences between the two and to explore the difference between the two and to understand how they fit together (Figure 1.1). Historically, the field of image processing grew from electrical engineering as an
