A CONTEXTUAL STUDY ON HIGHRESOLUTION REPEATED IMAGING OF MARS

This paper examines the meta-data of high-resolution orbital imagery obtained by Mars during the last four decades. The aim of this study is to provide a starting point for planetary scientists interested in exploring the martian surface for modifications linked to natural phenomena that aren't completely understood. A framework for generating picture groupings relevant to prioritising regions for shift detection is adopted and used. The season, the Martian Year, and the local period that an image was captured, as well as the imaging device and its resolution, are the criteria that determine each grouping. The research indicates that there is enough coverage to regularly analyse periodic martian phenomena in images depicting the same region during the same season, as well as intermittent martian phenomena (such as a new crater) in images depicting the same area in various time periods. This chapter largely serves as context details for future discussions. While our treatment of the human visual system is short, it offers a simple understanding of the eye's capabilities in perceiving pictorial details. To clean up noise and other defects in the data, to improve subtle information not noticeable in batch-processed NASA photos, and to magnify smaller features for study, we first used fairly standard image processing techniques. Many of these early findings were published in books.
