INTERVIEW AND SHORT ANSWER QUESTION ON IMAGE PROCESSING-BIOMEDICAL JOBS & NOTES QUESTION 21-40

21. Define subjective brightness and brightness adaptation?
Subjective brightness means intensity as preserved by the human visual system.
Brightness adaptation means the human visual system can operate only from
scotopic to glare limit. It cannot operate over the range simultaneously. It accomplishes
this large variation by changes in its overall intensity.

22. Define weber ratio
The ratio of increment of illumination to background of illumination is called as
weber ratio.(ie) ?i/i
If the ratio (?i/i) is small, then small percentage of change in intensity is needed
If the ratio (?i/i) is large , then large percentage of change in intensity is needed

PROCESING THE RADIOGRAPH-DIGITAL IMAGE PROCESSING NOTES

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

SUMMARY HAS BEEN GIVEN BELOW

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

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 .
