INTERVIEW AND SHORT ANSWER QUESTION ON IMAGE PROCESSING-BIOMEDICAL JOBS & NOTES-QUESTION NO 1-20

Define Image?
An image may be defined as two dimensional light intensity function f(x, y)
where x and y denote spatial co-ordinate and the amplitude or value of f at any point
(x, y) is called intensity or grayscale or brightness of the image at that point.

PROCESING THE RADIOGRAPH-DIGITAL IMAGE PROCESSING NOTES

LINK UPDATED

THIS IS THE BEST ARTICLE ON PROCESSING THE RADIOGRAPH AS FAR AS DIGITAL IMAGE PROCESSING IS CONCERNED

SUMMARY HAS BEEN GIVEN BELOW

FULL ARTICLE CAN BE DOWNLOADED FROM THIS LINK GIVEN BELOW IT IS REALLY INFORMATIVE AND EASY TO LEARN

IT IS A SURE SHOT QUESTION OF MDU ROHTAKL ALSO.

SUMMARY

When an X-ray film has been exposed, it must be processed in order to produce a

permanent visible radiographic image that can be kept without deterioration for a number of

years. Processing transforms the latent image into a visible image. The term for the

several procedures that collectively produce the visible, permanent image is processing

and consists of developing, rinsing, fixing, washing and drying procedures

SHORT NOTES ON DIGITAL IMAGE PROCESSING-BIOMEDICAL NOTES

IMAGE   PROCESSING

In this article, the basics of capturing an image, image processing to modify and enhance the image are discussed. There are many applications for Image Processing like surveillance, navigation, and robotics. Robotics is a very interesting field and promises future development so it is chosen as an example to explain the various aspects involved in Image Processing .

Brain scans reveal what's in your mind's eye

Brain scans reveal what's in your mind's eye

Scientists are getting closer to being able to create an image of whatever you’re picturing your mind. This is either completely amazing or absolutely terrifying. Maybe a little bit of both.

To construct their model, the researchers used an fMRI machine, which measures blood flow through the brain, to track neural activity in three people as they looked at pictures of everyday settings and objects.As in the earlier study, they looked at parts of the brain linked to the shape of objects. Unlike before, they looked at regions whose activity correlates with general classifications, such as “buildings” or “small groups of people.”
