Printed Thai Character Recognition using Shape Classification in Video Sequence along a Line
This paper presents a novel method for recognition of 68 printed Thai characters in image sequences captured along a line of characters, based on their shape appearance such as the height and width, the top, bottom, and right edges, the numbers and positions of the circles (head of Thai characters) and the end points. Since each character appears in more than one frame of the image sequence that moves along the line, an algorithm to identify the arrangement of the characters in each line is necessary for accurate recognition results. We tested our system on image sequences with four different Thai fonts. The recognition rate is about 85.64% correct.
