Question 332

Image Compression Efficiency

A software engineer wants to test a new image compression algorithm, 'OptiShrink', against standard JPEG compression. They want to determine if images compressed with OptiShrink are more likely to be classified as 'Visually Lossless' compared to those compressed with JPEG. A panel of independent reviewers categorizes each compressed image as either 'Lossless' or 'Lossy'.

Explain one advantage of collecting nominal data in this study.
