Abstract

This study explores various image enhancements techniques for documentation and analysis of rock-art sites in India. A Nikon Coolpix AW130 camera and Samsung m30s mobile camera was extensively used for photo documentation and digital preservation.These images were later processed using ImageJ and D-Stretch softwares to enhance the panels and paintings, obtain comprehensive counts of individual paintings, and interpret superimposition patterns. A mobile version of D-Stretch software 'aD-Stretch' was used on-site for quick results and reference. This talk will explore basic methodology, results obtained, and their implications in the interpretation of these rock-arts in their archaeological contexts.
