Question 1

Please match the following digital image processing concepts for each group. Answer selections may be used more than once.

-This technique can result in the scaling and sizing of images

Accepted Answer

Geometrical operations involve transformations that change the spatial relationship of pixels, such as scaling and sizing of images.

Question 2

Explain briefly what is meant by convolution.

Accepted Answer

The answer of Explain briefly what is meant by convolution....

Question 3

The number of bits per pixel is the bit formation.

Accepted Answer

The number of bits per pixel is referred to as color depth or bit depth, not bit formation.

Question 4

Please match the following digital image processing concepts for each group. Answer selections may be used more than once.

-A common operation in this processing technique is Fourier domain processing

Accepted Answer

Fourier domain processing is a global operation because it involves transforming the entire image into the frequency domain and manipulating it as a whole.

Question 5

Digital image processing was first developed for NASA's work in lunar and planetary exploration.

Accepted Answer

Digital image processing techniques were initially developed by NASA to enhance images of the moon and planets taken by spacecraft, allowing for better analysis and interpretation.

Question 6

The Fourier transform is used to transform one image domain into another image domain.

Accepted Answer

The Fourier transform is a mathematical technique used to convert an image from the spatial domain to the frequency domain, allowing for analysis and manipulation of the image's frequency components.

Question 7

A larger matrix results in a larger pixel size.

Accepted Answer

A larger matrix results in smaller pixel size, as the same area is divided into more pixels, making each pixel smaller.

Question 8

Please match the following digital image processing concepts for each group. Answer selections may be used more than once.

-In the operation, the entire input image is used to compute the value of the pixel in the output image

Accepted Answer

Global operations involve using the entire input image to compute the value of each pixel in the output image, as opposed to point or local operations which use individual pixels or small neighborhoods.

Question 9

Please match the following digital image processing concepts for each group. Answer selections may be used more than once.

-Spatial frequency filtering is an example of this operation

Accepted Answer

Spatial frequency filtering involves operations that consider a neighborhood of pixels, making it a local operation.

Question 10

Please match the following digital image processing concepts for each group. Answer selections may be used more than once.

-Gray-level mapping

Accepted Answer

Gray-level mapping is a point operation because it involves modifying the intensity of each pixel independently based on a predefined mapping function.

Question 11

Computers operate using the binary number system which operates with a base of 10.

Accepted Answer

Computers operate using the binary number system, which has a base of 2, not 10.

Question 12

Please match the following digital image processing concepts for each group. Answer selections may be used more than once.

-Most frequently used image processing technique

Accepted Answer

Point operations are the most frequently used image processing technique as they involve modifying individual pixel values based on a transformation function, which is a common and fundamental operation in image processing.

Question 13

Please match the following digital image processing concepts for each group. Answer selections may be used more than once.

-Also called area processes or group processes

Accepted Answer

Local operations involve processing a group of pixels or an area of the image, hence they are also known as area or group processes.

Question 14

What is the purpose of the host computer in a digital image processing system?

Accepted Answer

The answer of What is the purpose of the host...

Question 15

What are the components of a digital image processing system?

Accepted Answer

The answer of What are the components of a digital...
