Biography
Charles O. Onyekweli in 2012 obtained a Masters degree in Information Technology Management from The Roberts Gordon University (RGU); Aberdeen, Scotland and in 2007, a Bachelors degree in Computer Science from Benson Idahosa University (BIU); Benin City, Nigeria. He is currently an ASSISTANT LECTURER with the Department of Computer Science at The Delta State University; Abraka, Nigeria. He has previously worked as an IT BUSINESS ANALYST and IT HELPDESK OFFICER (VOLUNTEER) at RGU, IT SUPERVISOR at United Africa Company of Nigeria (UACN) Plc., and COMPUTER SYSTEM ENGINEER at National Bureau of Statistics among other corporate positions. He has also over the past couple of years and in collaboration with other authors, published a few articles relevant to some of his areas of interest. These interests bother on Computer process and Security Improvement, Human Computer Interaction, Mobile Device Management, Strategic IT Management, IT Project Management, among others.

Edge detection is important in image processing to aid operations such as object classification and identification amongst others. This is soley to improve interpretability of the image. Common edge detection techniques such as Sobel, Prewittt, Canny, Laplacian of Gaussian (LOG), Robertss and Zero-Crossing has attracted the attention of researchers to perform a comparative analysis on these techniques excepts fuzzy, using different type of images. Fuzzy logic based edge detection algorithms development and comparison with existing algorithm became important due to the fact that the pixels’ boundaries identifying image degs are crystal clear as expected, hence other edge detection algorithms using crisp values will be omitting some vital information pixels, this impairs the quality of the image edge detected and further application through proper interpretation. This research further extends the investigation of edge detection techniques optimality, through comparing Sobel, Prewittt, Canny, Laplacian of Gaussian (LOG), and Robertss edge detection algorithms with our proposed fuzzy based edge detection algorithm designed using MATLAB. The result indicated that the novel fuzzy based edge detection algorithm developed in this research outperforms the Canny, Sobel, Prewittt, Robertss and LOG edge detection algorithms in three different experiments with different images
