How can one reduce the aliasing effect on an image?

Statement (I): Aliasing occurs when the sampling frequency is less than twice the maximum frequency in the signal. Statement (II): Aliasing is a reversible process.

A

Both statement (I) and Statement (II) are individually true and Statement (II) is the correct explanation of Statement (I).

B

Both Statement (I) and Statement (II) are individually true but Statement (II) is not correct explanation of Statement (I)

C

Statement (I) is true but Statement (II) is false

D

Statement (I) is False but Statement (II) is true

Let us suppose an image containing a quite small square under a large dark square with both having very close gray level values. If an image contains some of this such that the small squares can’t be visualized and some noise blurred enough to reduce its noise content as shown in fig. below, Which of the following method would be preferred for obtaining the small square clear enough? Figure: original image.

A

Global histogram equalization

B

Local histogram equalization

C

All of the mentioned
