1.	A process that accentuate the contribution to enhancement made by high-frequency components, by multiplying the highpass filter by a constant and adding an offset to the highpass filter to prevent eliminating zero frequency term by filter is known as _______(a) Unsharp masking(b) High-boost filtering(c) High frequency emphasis(d) None of the mentionedI got this question in an interview.Question is taken from Unsharp Masking, High-boost filtering and Emphasis Filtering topic in division Intensity Transformations and Spatial Filtering of Digital Image Processing
Answer» The CORRECT choice is (C) HIGH frequency emphasis Explanation: High frequency emphasis is the method that accentuate the contribution to enhancement made by high-frequency component. In this we multiply the HIGHPASS FILTER by a constant and add an offset to the highpass filter to prevent eliminating zero frequency term by filter.
