Question

Which of the following depicts the main functionality of the Bit-plane slicing?

(a) Highlighting a specific range of gray levels in an image

(b) Highlighting the contribution made to total image appearance by specific bits

(c) Highlighting the contribution made to total image appearance by specific byte

(d) Highlighting the contribution made to total image appearance by specific pixels

This question was posed to me in class test.

My enquiry is from Basic Intensity Transformation Functions in section Intensity Transformations and Spatial Filtering of Digital Image Processing

Answer 1

Correct choice is (b) Highlighting the contribution made to total image appearance by specific bits

The best I can explain: Instead of highlighting gray-level ranges, highlighting the contribution made to total image appearance by specific bits might be desired. Suppose , each pixel in an image is represented by 8 bits. Imagine that the image is composed of eight 1-bit planes, ranging from bit-plane 0 for the least significant bit to bit-plane 7 for the most significant bit. In terms of 8-bit bytes, plane 0 contains all the lowest order bits in the bytes comprising the pixels in the image and plane 7 contains all the high-order bits.
