86 Comparison of Edge Detection Methods in Hexagonal and Square Structure Images Nader Eydi n eydi@ec iut ac ir Date of Submission 2015 02 6 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language FarsiSupervisor Raoul Amirfattahi fattahi@cc iut ac irAbstract Sampling network has an important role in the digitization of two dimensional image signals Alsovarious schemes have been proposed to take samples of two dimensional signals due to the characteristics ofthe square structure square pixels the use of this structure has been common in the production of digitalimages In some applications one of the structures that can be replaced with square structure is hexagonalstructure In many previous works hexagonal structure features and its benefits have been reviewed andshown that it can be an image structure alternative to traditional square image structure In addition one ofthe most widely operations used in image processing is edge detection that is the main base of many otherprocessing such as object detection So in this research at first hexagonal structure features have beenexamined and then the conversion of digital images with square pixels to hexagonal pixel approaches havebeen reviewed and implemented After that three edge detection operators include canny sobel andmorphology have been implemented on the hexagonal images Performance of edge detection operators insquare and hexagonal structures are compared with each other in simulation results Results showed that inmany cases edge detection operators in hexagonal structure have better performance than square structureand in some specific applications it can be used instead of square structures Keywords Hexagonal Structure Images Square Structure Images Edge Detection
