Abstract:
We aim to provide grammar error feedback to learners. It is known that grammar error detection and feedback are challenging problems in written language, however, they become much more difficult tasks in oral conversation because it is difficult for a system to judge whether an error is due to grammar or automatic speech recognition (ASR). False alarms occur when a learner correctly utters a remark, but the system gives feedback implying an error. Minimizing the false alarm rate is especially critical in education applications because it is imperative that the tutor give correct instruction to learners. Thus, to reduce the false alarm rate in grammar error detection and feedback, we apply a partially observable Markov decision process (POMDP) when the system provides feedback about a learner’s mistake. The POMDP models uncertainty between grammar errors and ASR errors. An additional advantage of our method is that “belief states in POMDP can be used for learner models which indicate each individual learner’s grammar comprehension level.

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.
If you have worked on any part of image processing prepare a research paper and submit to us

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…..

To contribute your research work in Image processing please prepare an article on it and submit to us.

The strangest animals ever discovered

TwilightBeasts

I love reading through Charles Darwin’s diaries. Who wouldn’t? Written in his early 20s, Darwin writes detailed accounts of his days on board HMS Beagle. For me, these are accounts of fantastic, real, adventures: travelling where no Englishman had travelled before, discovering new animals and plants, and finding gigantic creatures trapped in the rocks. His own words, scrawled in his cramped cabin, or beneath the clear South American night transports you back with him.

Who doesn’t dream of adventure like that? I am a strong believer in creating your own adventures in life, yet there is something wonderfully romantic about being swept away in somebody else’s.

Darwin was almost never on the Beagle. A young Robert Fitzroy unexpectedly took command of the big ship during it’s first voyage when the captain shot himself. It wasn’t unusual for captains to fall into depression on long voyages away from home. Fitzroy was paranoid and…
