9. A typical size comparable in quality to monochromatic TV image is of size.
Choose the correct option:

  • a) 256 X 256

  • b) 512 X 512

  • c) 1920 X 1080

  • d) 1080 X 1080

A normal T.V have 512 x 512 resolution.

10. What is the correct sequence of steps in image processing?
Choose the correct option:

  • 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

Steps in image processing:

1. To convert a continuous sensed data into Digital form, which of the following is required?
Choose the correct option:

  • a) Sampling

  • b) Quantization

  • c) Both Sampling and Quantization

  • d) Neither Sampling nor Quantization

Explanation: The output of the most sensor is a continuous waveform and the amplitude and spatial behavior of such waveform are related to the physical phenomenon being sensed.

6. How is sampling been done when an image is generated by a single sensing element combined with mechanical motion?
Choose the correct option:

  • a) The number of sensors in the strip defines the sampling limitations in one direction and Mechanical motion in the other direction.

  • b) The number of sensors in the sensing array establishes the limits of sampling in both directions.

  • c) The number of mechanical increments when the sensor is activated to collect data.

  • d) None of the mentioned.

Explanation: When an image is generated by a single sensing element along with mechanical motion, the output data is quantized by dividing the gray-level scale into many discrete levels. However, sampling is done by selecting the number of individual mechanical increments recorded at which we activate the sensor to collect data.

7. How does sampling gets accomplished with a sensing strip being used for image acquisition?
Choose the correct option:

  • a) The number of sensors in the strip establishes the sampling limitations in one image direction and Mechanical motion in the other direction

  • b) The number of sensors in the sensing array establishes the limits of sampling in both directions

  • c) The number of mechanical increments when the sensor is activated to collect data

  • d) None of the mentioned

Explanation: When a sensing strip is used the number of sensors in the strip defines the sampling limitations in one direction and mechanical motion in the other direction.
