Question

The general form of log transformations is ____________________

(a) s = c.log(1 + r)

(b) s = c+log(1 + r)

(c) s = c.log(1 – r)

(d) s = c-log(1 – r)

I had been asked this question in an interview for internship.

I'd like to ask this question from Intensity Transformation Functions in chapter Intensity Transformations and Spatial Filtering of Digital Image Processing

Answer 1

Correct answer is (a) s = c.log(1 + r)

The explanation is: s = c.log(1 + r) is the log transformation.
