              TWO MARKS



1. 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.

2. What is Dynamic Range?

The range of values spanned by the gray scale is called dynamic range of an image. Image will have high contrast, if the dynamic range is high and image will have dull washed out gray look if the dynamic range is low.

3. Define Brightness? (Dec’12)

Brightness of an object is the perceived luminance of the surround. Two objects with different surroundings would have identical luminance but different brightness.

4. Define Contrast (Dec’12)

It is defined as the difference in intensity between the highest and lowest intensity levels in an image

5. What do you mean by Gray level?

Gray level refers to a scalar measure of intensity that ranges from black to grays and finally to white.

6. What do you meant by Color model?

A Color model is a specification of 3D-coordinates system and a subspace within that system where each color is represented by a single point.

7. List the hardware oriented color models?

  • RGB model
  • CMY model
  • YIQ model
  • HSI model

8. What is Hue & saturation?(May’14)

Hue is a color attribute that describes a pure color where saturation gives a measure of the degree to which a pure color is diluted by white light.

9. List the applications of color models?

  1. RGB model— used for color monitor & color video camera
  2. CMY model—used for color printing
  3. HIS model—-used for color image processing
  4. YIQ model—used for color picture transmission

10. Define Resolution

Resolution is defined as the smallest number of discernible detail in an image. Spatial resolution is the smallest discernible detail in an image and gray level resolution refers to the smallest discernible change is gray level.
