Abstract
In this paper, an extraction method of the handwritten character string superimposed on the delivery slip is proposed. First of all, the HSL transform is given to the delivery slip image input from the TV camera. The chroma color aspect distribution chart is made by using the saturation and the hue obtained by the HSL transform. The cluster is extracted from this chroma distribution chart and a binary code character area is extracted by using the adjustment threshold method. In this case, void elements exist in the obtained binary image, so the element is restored from a binary image by lightness information. The code character is extracted by using structural elements in the morphological filter, whose diameter is equal to the width of the average line estimated from a binary image. All characters were extracted from 200 characters of 50 images as a result of the extraction experiment.
