Question

Which one of the following is NOT used to assess the quality of remote sensing image?

• A. Univariate statistics of image
• B. Histogram
• C. Multivariate statistics of image
• D. Swath of the image

Hint:

Image quality is assessed using statistical tools like histograms and multivariate analysis, not spatial coverage measures like swath.

Answer 1

The Correct Option is D

Swath refers to the width of the ground area captured by a satellite sensor in a single pass. It relates to spatial coverage rather than image quality. Univariate and multivariate statistics, as well as histograms, are commonly used to assess image quality.
