Question 26. What Is Meant By Illumination And Reflectance?

Illumination is the amount of source light incident on the scene. It is represented as i(x, y). Whereas, Reflectance is the amount of light reflected by the object on the scene. It is represented by r(x, y).

Question 27. List The Categories Of Digital Storage in OpenCV?

They are as follows

– Short term storage for use during processing.

– Online storage for relatively fast recall.

– Archival storage for infrequent access.

Question 28. What Are The Differences Between Structural Patterns & Morphological Structural Element?

In software engineering, structural design patterns are design patterns that ease the design by identifying a simple way to realize relationships between entities.

Question 29. Define Resolutions.

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.

Question 30. What Is Image Translation And Scaling?

Image translation means reposition the image from one co-ordinate location to another along straight line path. Whereas, Scaling refers to alter the size of the object or image (ie) a co-ordinate system is scaled by a factor.
