Which image enhancement technique stretches the range of pixel intensity values to cover the full dynamic range of display devices?
Show Hint
Contrast stretching = Expands pixel intensity range for better display contrast.
Updated On: Jun 16, 2025
- Level slicing
- Contrast stretching
- Gray level thresholding
- Histogram equalization
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Contrast stretching improves the visibility of features in an image by expanding the range of intensity levels. It maps low and high input values to a broader output range, making use of the full display capacity.
