What is image processing? Images are everywhere, from those we take with our digital cameras and/or mobile devices and share with our family members and friends to those that we see in the movies and receive from Mars, as well as the whole ensemble of images of our bodies that are taken at dentist office or in hospital visits. Image processing is the art of working with such images. From making it possible to capture, transmit, and store them as blurry and dark images for analyzing the medical data to recognizing our family members and friends’ faces in social pictures.
There were two robot geologists were launched to Mars in summer 2003 and landed in January 2004. After over eight Earth years, one is still operating. While searching for liquid water on Mars, they took pictures and sent back to Earth so NASA scientists could analyze. How could they do that? They put a camera on the robot, and the pictures were sent to NASA after they were taken. The computer scientists used image management technology such as metadata to interpret, analyze, and store those pictures. Using metadata, they could define the width, height, size, file name and directory, and the date the pictures were taken. They converted between Mars and Earth time. They used Java Message Service for synchronous and asynchronous messaging.
