Review of two dimension geometric shape detection methods

Abstract

Geometric shapes and geometric features are indeed involved in a wide variety of digital images. Much of
these features carry within itself useful information that can be exploited for a broad range of real-world
applications. Circle, rectangle and triangle features found in man-made environment frequently. Most approach
developed for regular geometric shapes are based on synthetic images. Basically geometric shape detection methods
broadly classified in three groups- based on Hough transform, detection by intelligent methods and detection by
geometric property. A review of some geometric shape detection methods are collected and presented here.
