Image Processing
Any form of information processing for which the input is an image and the out-
put is for instance a set of features of the image.
Image Resolution
The number of rows and columns of pixels in an image. The total number of pix-
els of an image sensor.
Image Sensor
Device converting a visual image to an electric signal. It is usually an array of
CCD (Charge Coupled Devices) or CMOS (Complementary Metal Oxide Semicon
-
ductor) pixel sensors.
IEC
(International Electrotechnical Commission): Global organization that publishes
international standards for electrical, electronic, and other technologies.
IP Address
The terminal’s network address. Networks use IP addresses to determine where
to send data that is being transmitted over a network. An IP address is a 32-bit
number referred to as a series of 8-bit numbers in decimal dot notation
(e.
g.,
130.24.34.03). The highest 8-bit number you can use is 254.
ISO
(International Organization for Standardization): A network of the national stan-
dards institutes of several countries producing world-wide industrial and com-
mercial standards.
LED (Light Emitting Diode)
A low power electronic light source commonly used as an indicator light. It uses
less power than an incandescent light bulb but more than a Liquid Crystal Dis
-
play (LCD).
LED Illuminator
LED technology used as an extended lighting source in which extra optics added
to the chip allow it to emit a complex radiated light pattern.
Matrix Symbologies (2D Codes)
An arrangement of regular polygon shaped cells where the center-to-center dis-
tance of adjacent elements is uniform. Matrix symbols may include recognition
patterns which do not follow the same rules as the other elements within the
symbol.
Multi-row (or Stacked) Symbologies
Symbologies where a long symbol is broken into sections and stacked one upon
another similar to sentences in a paragraph.
RAM
Random Access Memory. Data in RAM can be accessed in random order, and
quickly written and read.
