THE INFLUENCE OF SHORT-TERM MEMORY IN SUBJECTIVE IMAGE QUALITY ASSESSMENT

Abstract

This study delves into the subjective image quality assessment, exploring individuals' perceptions of image quality when comparing different formats of the same image. Using various image formats, such as jpg, tiff, bmp, gif, and png, alongside the original image, the research investigates observers' ability to discern image quality differences. The results reveal a notable divergence in observers' opinions, particularly when assessing image quality sequentially or side by side. The study uncovers a tendency for observers to either overestimate their accuracy in sequential assessments or underestimate themselves when conducting one-by-one evaluations prior to side-by-side comparisons. This research sheds light on the complexities of subjective image quality assessment and its variations based on assessment methods, providing valuable insights into human perceptions of visual quality.
