Exercises

These questions are designed to have the reader go beyond the traditional method of answering questions. They involve using the concepts designed in the chapter and doing additional research on the Internet to come up with the best solution to address the questions raised:

  • Define the attributes of a digital type that would be used to be a three-dimensional representation composed of a set of scanned images of a real-world object, like a vase in a museum or a wrecked car in a crime scene.
  • With the huge rise in the popularity of multi-player gaming, there will come a time when matches between players will be stored, just like sporting match videos are stored. Though video of these matches can be used as a simple capture method, it doesn't capture the players themselves or the multi-view capability these games offer. It also would not allow searching, like finding the scene where player A discovered the ambush of player B. It should also be possible to search for all games that featured player A winning against player C. Detail a digital object structure and its data types that can not only capture digitally all this information, but allow for it to be easily searched against historically and against abstract concepts.
  • Describe the compression method invented by Kodak called V-mail during the Second World War. Was it lossless or lossy? Can this technology be adapted for use by any digital systems today?
  • With robotic space exploration, a cost-effective and popular method for discovering what is on distant planets, planetoids, asteroids, and comets is via autonomous robots. Describe a universal type, including the compression method for sampling the chemicals found in the atmosphere. Of importance is that the sampling is continuous over multiple locations and is the must factor in any local weather conditions. As it's continuous, it must be accurately time-stamped, factoring in that the time on remote locations will not match to earth time. It must also handle data loss due to solar activity or partial data transfer, with the notion that it's better to get some data, uncompress it, and get some results back rather than nothing.
  • When looking at postcard images, the pixel dimensions are fixed. Determine an algorithm to create a postcard image when the images themselves are based on objects of unusual size. In particular objects such as a tapestry, which might have original dimensions of 1000 x 60 and is square in shape.
