Abstract
This paper proposes a method to generate a high-resolution document image from plural low-resolution images with almost same view areas that are captured by a handy camera. The relations between the locations of pixels in the high-resolution image and the types of low-resolution images are determined by the genetic algorithm. The individual chromosome is represented by the two-dimensional array of genes that include integers to distinguish low-resolution images. When the high-resolution image is supposed to have fine definition and sharpness, a higher fitness is given to the individual. The experimental results show that the high-resolution images with good quality were generated by the proposed method because the visual readability of the characters in the image was improved.
