If R happens to be a subset of pixels, and if R is a connected set, we will call R to be a _________ of the image

• Adjacent

• Closed

• Region

• Disjoint

The types of images are generated by the combination of an “illumination” source and ___ of energy from that source by the elements of the “scene” being image

• Reflection

• Refraction

• Luminance

• Transmittance

The process of using known data to estimate values at unknown locations is called

• acquisition

• interpolation

• pixelation

• none of the mentioned

In a digital image of MxN and L discrete gray levels, calculate the bits required to store a digitized image for M=N=32 and L=16

• 16384

• 4096

• 8192

• 512

An image of 4x4 is interpolated to 100x100, find the ratio of interpolation

• 25

• 50

• 24.5

• 26

If S is a subset of pixels, pixels p and q are said to be ____________ if there exists a path between them consisting of pixels entirely in S

• 
  continuous

• ambiguous

• connected

• none of the mentioned

The distance between pixels p and q, the pixels have a distance less than or equal to some value of radius r centred at (x,y) is called :

• city-block distance

• chessboard distance

• Rugby Distance

• 
  euclidean distance

The general form of log transformations is

• s = c.log(1 + r)

• s = c+log(1 + r)

• s = c.log(1 – r)

• s = c-log(1 – r)

Consider the array of pixels

12, 23, 4, 75, 245, 67, 9,10, 18, 16

MinMax Value at 5th pixel:

• 144

• 69

• 17

• 47

Consider the below pixel matrix, and provide m-adjacency of (1,1):

0 1 1

0 1 0

0 0 1

• (0,1),(0,2)

• (0,1)(2,2)

• (0,1)

• (0,2)
