Quantification of Streaking Effect Using Percentage Streak Area

The Streaking effect is an artifact or characteristic fingerprint left by the application of median filter. Many studies have used the application of median filters on digital images. Recently, percentage streaking area (PSA) has been used as a metric to measure streaking in images. The paper performs an analysis of the percentage streak area (PSA). The work investigates streaking effect using PSA in natural images and when commonly applied filters such as Gaussian filter, Average filter, and Unsharp masking are used for image filtering. Standard image datasets UCID, BOSS, and Dresden have been used in the study, and results are presented. The investigation shows that the streaking effect can be quantified by the percentage streak area.
