  1. What is pixel?
    a) Pixel is the elements of a digital image
    b) Pixel is the elements of an analog image
    c) Pixel is the cluster of a digital image
    d) Pixel is the cluster of an analog image

Answer: a
Explanation: An Image is a collection of individual points referred as pixel, thus a Pixel is the element of a digital image.

  1. The range of values spanned by the gray scale is called:
    a) Dynamic range
    b) Band range
    c) Peak range

    a) Saturation
    b) Hue
    c) Brightness
    d) Intensity

Answer: b
Explanation: The color attribute of an image refers to the contrast of colors, which can be controlled using the Hue values.

  1. Which gives a measure of the degree to which a pure colour is diluted by white light?
    a) Saturation
    b) Hue
    c) Intensity
    d) Brightness

Answer: a
Explanation: Saturation is color recognizing capability of the human eye. Hence a degree of dilution is measured using saturation.

    a) Interpretation
    b) Recognition
    c) Acquisition
    d) Segmentation

Answer: a
Explanation: The interpretation is called the assigning meaning to recognized object.

    b) 512 X 512
    c) 1920 X 1080
    d) 1080 X 1080

Answer: b
Explanation: A normal T.V have 512 x 512 resolution.

  1. The number of grey values are integer powers of:
    a) 4
    b) 2
    c) 8
    d) 1

Answer: b
Explanation: The gray values are interpreted as the power of number of colors. In monochromatic image the number of colors are 2.

“Steps in Image Processing”

  1. What is the first and foremost step in Image Processing?
    a) Image restoration
    b) Image enhancement
    c) Image acquisition
    d) Segmentation

Answer: c
Explanation: Image acquisition is the first process in image processing. Note that acquisition could be as simple as being given an image that is already in digital form. Generally, the image acquisition stage involves preprocessing, such as scaling.

  1. In which step of processing, the images are subdivided successively into smaller regions?
    a) Image enhancement
    b) Image acquisition
    c) Segmentation
    d) Wavelets

Answer: d
Explanation: Wavelets are the foundation for representing images in various degrees of resolution. Wavelets are particularly used for image data compression and for pyramidal representation, in which images are subdivided successively into smaller regions.

  1. What is the next step in image processing after compression?
    a) Wavelets
    b) Segmentation
    c) Representation and description
    d) Morphological processing

Answer: d
Explanation: Steps in image processing:
Image acquisition-> Image enhancement-> Image restoration-> Color image processing-> Wavelets and multi resolution processing-> Compression-> Morphological processing-> Segmentation-> Representation & description-> Object recognition.

  1. What is the step that is performed before color image processing in image processing?
    a) Wavelets and multi resolution processing
    b) Image enhancement
    c) Image restoration
    d) Image acquisition

Answer: c
Explanation: Steps in image processing:
Image acquisition-> Image enhancement-> Image restoration-> Color image processing-> Wavelets and multi resolution processing-> Compression-> Morphological processing-> Segmentation-> Representation & description-> Object recognition.

  1. How many number of steps are involved in image processing?
    a) 10
    b) 9
    c) 11
    d) 12

Answer: a
Explanation: Steps in image processing:
Image acquisition-> Image enhancement-> Image restoration-> Color image processing-> Wavelets and multi resolution processing-> Compression-> Morphological processing-> Segmentation-> Representation & description-> Object recognition.

6. What is the expanded form of JPEG?
a) Joint Photographic Expansion Group
b) Joint Photographic Experts Group
c) Joint Photographs Expansion Group
d) Joint Photographic Expanded Group

Answer: b
Explanation: Image compression is familiar (perhaps inadvertently) to most users of computers in the form of image file extensions, such as the jpg file extension used in the JPEG (Joint Photographic Experts Group) image compression standard.

7. Which of the following step deals with tools for extracting image components those are useful in the representation and description of shape?
a) Segmentation
b) Representation & description
c) Compression
d) Morphological processing

Answer: d
Explanation: Morphological processing deals with tools for extracting image components that are useful in the representation and description of shape. The material in this chapter begins a transition from processes that output images to processes that output image attributes.

8. In which step of the processing, assigning a label (e.g., “vehicle”) to an object based on its descriptors is done?
a) Object recognition
b) Morphological processing
c) Segmentation
d) Representation & description

Answer: a
Explanation: Recognition is the process that assigns a label (e.g., “vehicle”) to an object based on its descriptors. We conclude our coverage of digital image processing with the development of methods for recognition of individual objects.

9. What role does the segmentation play in image processing?
a) Deals with extracting attributes that result in some quantitative information of interest
b) Deals with techniques for reducing the storage required saving an image, or the bandwidth required transmitting it
c) Deals with partitioning an image into its constituent parts or objects
d) Deals with property in which images are subdivided successively into smaller regions

Answer: c
Explanation: Segmentation procedures partition an image into its constituent parts or objects. In general, autonomous segmentation is one of the most difficult tasks in digital image processing. A rugged segmentation procedure brings the process a long way toward successful solution of imaging problems that require objects to be identified individually.

10. What is the correct sequence of steps in image processing?
a) Image acquisition->Image enhancement->Image restoration->Color image processing->Compression->Wavelets and multi resolution processing->Morphological processing->Segmentation->Representation & description->Object recognition
b) Image acquisition->Image enhancement->Image restoration->Color image processing->Wavelets and multi resolution processing->Compression->Morphological processing->Segmentation->Representation & description->Object recognition
c) Image acquisition->Image enhancement->Color image processing->Image restoration->Wavelets and multi resolution processing->Compression->Morphological processing->Segmentation->Representation & description->Object recognition
d) Image acquisition->Image enhancement->Image restoration->Color image processing->Wavelets and multi resolution processing->Compression->Morphological processing->Representation & description->Segmentation->Object recognition

Answer: b
Explanation: Steps in image processing:
Image acquisition-> Image enhancement->Image restoration->Color image processing->Wavelets and multi resolution processing->Compression->Morphological processing->Segmentation->Representation & description->Object recognition.
