Today, computer vision is extensively used in non-industrial fields as well, for example, for identifying fingerprints or facial features of a suspect, distinguishing counterfeit notes and forged paintings, analyzing medical images and photographs taken by satellites, etc.
One of the most importance of these is animation, the capability to have moving images on your screen. Animation is tightly tied in with another concept called desktop video—actually creating and manipulating video images, to produce in-house presentations, rough drafts of commercial videos, or training products.

as "template matching". One by one, the templates are checked against the binary ion representing the scene. Once a match occurs, an object is identified. The template matching process continues until all possible objects in the scene have been identified, otherwise it fails (as shown in Fig.R20-2).

Modulation
a markedly different method from pulse modulation. The method involves first sampling the information signal, quantizing the sample by rounding off to the closest of a number of discrete levels, and finally generating a prescribed number of pulses according to a code related to the nearest discrete level. In the simplest system the code may determine the presence or absence of pulses in the prescribed number, or, alternatively, it may determine pulse sign. Both cases correspond to pulses having only two possible levels. More complicated systems are also feasible with pulses having a larger number of discrete levels.

Lesson 23 2D Bar Code
Barcodes are a combination of dark and light lines of variable widths. The dark lines are most commonly termed as bars and the light bands as spaces. The elements ( bars and spaces ) of these barcodes must be consistent and proportional thickness and thinness. What this means is that if the widest elements of the barcode can be as thick as a pencil or a credit card but the thinness of the thin elements has to be in proportion to the thick elements.
Chinese Translation of Texts
Barcodes are the easiest and the cheapest way of automatic data collection. i.e. Instead of an operator reading and punching the product codes by a keyboard at a retail counter, reading a barcode reads the data as well as enters the data into the host system. Thus making operations faster and efficient by reducing human errors.
A Bar Code cannot be read by a human eye. Therefore it is advisable to print the data encoded in a barcode close to the barcode genrally known as human readables. So the operator can read the data and enter it manually just in case the scanner stops functioning.

第23课 二维条形码
条形码是将宽度不同的黑白线条结合起来的一种码。黑线条通常称为条，而白 线条被称为空。这些条形码的元素（条和空）必须连贯且厚薄成比例。这意味着， 如果条形码的最宽的元素可以和铅笔或信用卡一样厚，那么最薄的元素必须与厚元 素成比例。
Chinese Translation of Texts
通过人眼无法读取条形码。因此，将一个条形码中被编码的数据打印出来是可 取的，这个条形码接近人类可读的条形码。操作者可以读取数据，并手动输入，以 防止万一扫描仪停止运作。
Chinese Translation of Texts
Two-dimensional scanners were far more expensive than 1D scanners when were introduced. Recent microprocessor developments have brought the cost of 2D scanners down to about 125% of the cost of a comparable 1D scanner. Also, advancing decoding algorithms have made scanning quicker and easier and provided even greater readability of excessively-damaged symbols. There are a number of two-dimensional symbologies in growing use today. They fall into two categories: matrix and stacked. An explanation of each is best done visually through the examples below—the difference is obvious.
