 DIGITAL IMAGE PROCESSING

Digital image processing deals with manipulation of digital images through a digital computer. It is a subfield of signals and systems but focus particularly on images. DIP focuses on developing a computer system that is able to perform processing on an image. The input of that system is a digital image and the system process that image using efficient algorithms, and gives an image as an output. The most common example is Adobe Photoshop. It is one of the widely used application for processing digital images.

§  Applications of Digital Image Processing

Some of the major fields in which digital image processing is widely used are mentioned below

ü  Image sharpening and restoration

ü  Medical field

ü  Remote sensing

ü  Transmission and encoding

ü  Machine/Robot vision

ü  Color processing

ü  Pattern recognition

ü  Video processing

ü  Microscopic Imaging

DIGITAL VIDEO PROCESSING

A video signal is the term used to describe any sequence of time varying images. A still image is a spatial distribution of intensities that remain constant with time while a time varying image has a spatial intensity distribution that varies with time. Movies (films) and television are both examples of video signals as are the signals that drive computer monitor, laptop and PDA displays. It is widely expected that video communications in particular will be the next application driving the mobile and handheld device market. This course should give you the tools to understand the components that are necessary for such systems to operate effectively

BLUE MATCHING & WEDGE MATCHING OF CORE & CAVITY

-
  BLUE MATCHING & WEDGE MATCHING OF CORE & CAVITY   Blue matching was the final stage of assembly work. It is the process in which both the core and cavity parting surface are matched exactly to avoid plastic flow during moulding (flash free). In this process a thin film of blue was applied on any one side, either core or cavity parting lines. The tool was closed; a slight force was applied and was opened. The high spots where blue is picked up was removed either by diamond file, oilstone or by pneumatic grinders, if it was irregular parting line; otherwise the parting line levels were surface ground. This process is done till blue matches on both halves evenly.               Wedge matching is a process in which wedges are ground and matched to the side cores ensuring efficient locking of side cores with the matching face and at the same time correct matching at the parting surface.    ...
