Abstract— This document talks about the use of image processing as one of the most crucial element of developing Futuristic Technologies in various fields.
I. 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 II. Concept behind image processing
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 Processing system includes treating images as two dimensional signals while applying already set signal processing methods to them..
III. Purpose of image processing
The purpose of image processing is divided into 5 groups. They are: 1. Visualization - Observe the objects that are not visible. 2. Image sharpening and .restoration - To create a better image. 3. Image retrieval - Seek for the image of interest.
4. Measurement of pattern – Measures various objects in an image. 5. Image Recognition – Distinguish the objects in an image.human-computer interaction, an intelligent machine might want to be able to display emotions—even if it does not actually experience them itself—in order to appear sensitive to the emotional dynamics of human interaction 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.
The two types of methods used for Image Processing are Analog and Digital Image Processing. 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.
Major advancement that moves beyond the traditional user interface to a more natural way of interacting with information. It is a natural user interface that allows people to interact with digital content the same way they have interacted with everyday items such as photos, paintbrushes and music their entire life: with their hands, with gestures and by putting real-world objects on the surface. Surface computing opens up a whole new category of products for users to interact with.
Surface Computer users can finger-paint digitally, resize and interact with photos and videos, and even "digitize" some real-life events, such as splitting up a restaurant bill and researching wines. The Surface Computer can recognize some real-world objects and creates onscreen versions to interact with.
Microsoft has just announced its Surface Computing technology, a project that has been kept under wraps for five years. Using a giant table-like display, users are able to draw, interact with media, and use another new technology called domino tagging, in which a real-life object on the computer's surface is identified...
