<br/><br/> ABSTRACT:  	Edge detection is one of the most commonly used operations in image analysis, and there are probably more algorithms in the literature for enhancing and detecting edges than any other single subject. The reason for this is that edges form the outline of an object. An edge is the boundary between an object and the background, and indicates the boundary between overlapping objects. This means that if the edges in an image can be identified accurately, all of the objects can be located and basic properties such as area, perimeter, and shape can be measured. Since computer vision involves the identification and classification of objects in an image, edge detection is an essential tool.  	There were several problems that were found and analyze and had been the focus of the research. And the problem had proven to have significant effects on the applying the Sobel Edge Detector in the field of plate registration detection. The problems that prove to have significant effect on the application are noise before the process, the amplified noise and the thickness of the lines that had been produced. In this paper, an enhanced algorithm for the Sobel Edge Detection had been made. The motivation for this research is to understand and solve the peoblems regarding the performance of the algorithm.
