Authors Rohit Patil, S. B. Patil from D.Y.Patil COE,Kolhapur R. N. Ghodpage, M.F. Radar from Indian Institute of Geomagnetism, India has made use of Image processing for studying the Ionospheric Activities. This article submitted to IJSRD contains the study of ionosphere which plays the main role in HF transmission. The equatorial ionospheric plasma bubbles that occur at the low-latitude F-region of the ionosphere and the irregularities associated with them are responsible for several interference and sudden disruption of transionospheric radio propagation up to Giga Hertz frequency range, interfering with the communication systems, including the GPS. A CCD-based all-sky imager with 180° field-of-view is used to take photographs of all sky on clear, moonless nights, to study the F-region dynamics through the imaging with optical filter OI 630.0 nm oxygen emission line.

They concluded that main objective of this work is to post process the obtained images from the CCD camera by rectifying the distortions introduced and mitigating the consequences of the Van Rhijn effect and atmospheric extinction. These high-quality All-sky imager data can be used to investigate several key characteristics of the plasma depletion observed from low latitude ground based station.

What is Image Processing?

Image processing is a method to convert an image into digital form and perform some operations on it, in order to get an enhanced image or to extract some useful information from it. It is a type of signal dispensation in which input is image, like video frame or photograph and output may be image or characteristics associated with that image. Usually Image Processingsystem includes treating images as two dimensional signals while applying already set signal processing methods to them.
It is among rapidly growing technologies today, with its applications in various aspects of a business. Image Processing forms core research area within engineering and computer science disciplines too.Image processing usually refers to digital image processing, but optical and analog image processing also are possible.
Analog or visual techniques of image processing can be used for the hard copies like printouts and photographs. Image analysts use various fundamentals of interpretation while using these visual techniques. The image processing is not just confined to area that has to be studied but on knowledge of analyst. Association is another important tool in image processing through visual techniques. So analysts apply a combination of personal knowledge and collateral data to image processing.
Digital Processing techniques help in manipulation of the digital images by using computers. As raw data from imaging sensors from satellite platform contains deficiencies. To get over such flaws and to get originality of information, it has to undergo various phases of processing. The three general phases that all types of data have to undergo while using digital technique are Pre- processing, enhancement and display, information extraction.

Image processing basically includes the following three steps.

Importing the image with optical scanner or by digital photography.The acquisition of images (producing the input image in the first place) is referred to as imaging.
Analyzing and manipulating the image which includes data compression and image enhancement and spotting patterns that are not to human eyes like satellite photographs.
Output is the last stage in which result can be altered image or report that is based on image analysis.

Purpose of Image processing

The purpose of image processing is divided into various groups. They are:

Visualization – Observe the objects that are not visible.
Image sharpening and restoration – To create a better image.
Image retrieval – Seek for the image of interest.
Measurement of pattern – Measures various objects in an image.
Image Recognition – Distinguish the objects in an image.

Applications of Image processing

Image processing has been an important stream of Research for various fields. Some of the application areas of Image processing are….

Intelligent Transportation Systems – E.g. Automatic Number Plate Recognition, Traffic Sign Recognition

Remote Sensing –E.g.Imaging of earth surfaces using multi Spectral Scanners/Cameras, Techniques to interpret captured images etc.

Object Tracking – E.g. Automated Guided Vehicles, Motion based Tracking, Object Recognition
Defense surveillance – E.g. Analysis of Spatial Images, Object Distribution Pattern Analysis of Various wings of defense. Earth Imaging using UAV etc.

Biomedical Imaging & Analysis – E.g. Various Imaging using X- ray, Ultrasound, computer aided tomography (CT) etc. Disease Prediction using acquired images, Digital mammograms.etc.

Automatic Visual Inspection System – E.g.Automatic inspection of incandescent lamp filaments, Automatic surface inspection systems, Faulty component identification etc.

And many other applications…..
