Q1.
The principal factor to determine the spatial resolution of an image is _______
Q2.
What causes the effect, imperceptible set of very fine ridge like structures in areas of smooth gray levels?
Answer: (a).Caused by the use of an insufficient number of gray levels in smooth areas of a digital image
Q3.
What is the name of the effect caused by the use of an insufficient number of gray levels in smooth areas of a digital image?
Q4.
Using rough rule of thumb, and assuming powers of 2 for convenience, what image size are about the smallest images that can be expected to be reasonably free of objectionable sampling checkerboards and false contouring?
Answer: (b).256*256pixels and 64 gray levels
Q5.
What does a shift up and right in the curves of isopreference curve simply means? Verify in terms of N (number of pixels) and k (L=2k, L is the gray level) values.
Answer: (c).Larger values for N and k, implies better picture quality
Q6.
How does the curves behave to the detail in the image in isopreference curve?
Answer: (d).Curves tend to become more vertical as the detail in the image increases
Q7.
For an image with a large amount of detail, if the value of N (number of pixels) is fixed then what is the gray level dependency in the perceived quality of this type of image?
Answer: (b).Nearly independent of the number of gray levels used
Q8.
What is a band-limited function?
Answer: (a).A function of limited duration whose highest frequency is finite
Q9.
For a band-limited function, which Theorem says that “if the function is sampled at a rate equal to or greater than twice its highest frequency, the original function can be recovered from its samples”?
