Application of Digital Image Processing for Shape Characterization of Sand Particles

Abstract - This part of research work is focused on defining sand particles shape using Digital Image Processing (DIP). Sand particles shape can be defined using geometrical structures which involves mathematics and its derivatives. Shape descriptor is utilized to define exactly the sand particles shape. It describes the region or boundary of sand particles. So study of sand shape using digital image processing with Fourier analysis gives an exact particles shape. This research utilizes nondestructive automation technique online or off-line based on using image processing. It is revealed that total 21 different shape of sand particles were identified each having different measures. Sand shapes were analyzed and processed using Charge Coupled Devices (CCD) camera, image processing Matrox Imaging Library (MIL) Software and in MatLab 6.5 platform. This new way of vision which cannot be revealed by eye can characterize particles shape easily. Research in shape similarity has a lot of challenges, some solutions and, and for same in use in different application.
