heal.abstract	This study explores the performance of two different computer-vision approaches,namely the circular Hough transform (CHT) and the determinant of Hessian (DoH), to crater detection on a digital terrain model of planet Mars. CHT exploits the edges of circular features such as craters, revealed after several steps of image processing. However, the performance of the standard version of CHT on the Martian digital terrain model generated poor results as the interference of noise from irrelevant features persistent in the processed DTM generated numerous false responses. On the other hand,published adaptations of CHT engaging additional labor to isolate much of the influence of noise were deemed as impractical for routine crater detection. As a substitute, DoH was successful in detecting the overwhelming majority of the craters appearing on a horizontal Martian terrain. The percentage of success deteriorated as topographically more complex surfaces were encompassed. Even though, DoH scored higher than CHT despite the perplexity because DoH proved to be less sensitive to the noise than CHT. Current results, although not optimal, encourage future research to improving the performance of DoH for routine crater detection undertakings.	en
