The aliasing effect on an image can be reduced using which of the following methods?
A. By reducing the high-frequency components of image by clarifying the image
B. By increasing the high-frequency components of image by clarifying the image
C. By increasing the high-frequency components of image by blurring the image
D. By reducing the high-frequency components of image by blurring the image
Answer:A
The aliasing effect on an image can be reduced using which of the following methods?
A. By reducing the high-frequency components of image by clarifying the image B. By increasing the high-frequency components of image by clarifying the image C. By increasing the high-frequency components of image by blurring the image D. By reducing the high-frequency components of image by blurring the image
Explanation: By adding additional frequency components to the sampled function, aliasing corrupts the sampled image. As a result, the most common method for decreasing aliasing effects on an image is to blur the image prior to sampling to lower its high-frequency components.
