An Improved Method for 7- Segment Numeric Character Recognition

摘要

Text information recognition is very important because of its vast application. Also for the digitalized system, now a day's in many applications numeric characters are represented in a digital manner i.e 7- segment representation. And recognition of the digital numerical character is getting more popularity day by day. In this paper we proposed a new method for recognizing the 7-segment numeric character. For this purpose we take each segment as a video frame input by web-cam using a red colored object. And then we apply our proposed algorithm which works into three steps: 1) detecting the red color from a frame and finding the frame either it is a row frame or column frame 2) applying a process called numeric character grouping which is done to set the frames into a certain category 3) and then according to the position of row and column of the segment or number of row and column of the segment, a particular numeric character is recognized. The results of the experiments are very promising. In our proposed method, if the frames can take properly then the recognition rate is 100%.
