Seven Segment Display Detection and Recognition using Predefined HSV Color Slicing Technique

Abstract

Detection and recognition of LED seven segment panels present a particular challenge of locating characters among background clutter. This study proposed a framework based on a predefined HSV color slicing technique. The results demonstrate the framework's superiority over other color slicing methods with 94.46% precision, 92.24% recall, and 87.17% accuracy rates. The digit detection and recognition with the proposed predefined HSV color slicing is simple and straightforward - making it an attractive solution for the future deployment for edge-computing.
