COLOR CLASSIFICATION METHOD FOR COLOR BASED IMAGE CODE RECOGNITION

摘要

A color determination method of a color based image code is provided to perform conversion into an original color or shading and correct noise even though color, shading, and shape of the color based image code are distorted by characteristics of a camera or a print medium. A color determination method of a color based image code comprises the following steps of: sampling a predetermined number of pixels from each cell forming the color based image code(S1300); grasping a color of a color channel, having the biggest value among color channels forming each sampled pixel, as a color of each pixel(S1310); and determining a color, having the highest frequency among the colors of the pixels sampled from each cell, as a color of the cell(S1320).
