摘要: A mixed code, and a method and apparatus for encoding the same are provided. The mixed code includes a first code image region storing a first code image obtained by encoding first information using color, shading, or a combination thereof, and a second code image region storing a second code image obtained by encoding second information using color, shading, or a combination thereof. The first code image and/or the second code image includes the results of encoding interpretation information, construction information, error control information, and code direction information. The mixed code is made by adjusting the difference in color and brightness between the first and second code images to a predetermined level and combining these images.

摘要: Provided are a method and apparatus for decoding a mixed code that is a combination of first and second code images. In the method, a mixed code image is obtained by receiving the original image having the mixed code image and removing noise from the original image. Next, the colors, shades, and brightnesses of pixels of the mixed code image are categorized into groups based on a predetermined threshold, the mixed code image is divided into first and second code images, and first and second information are extracted by decoding the first and second code images, respectively. The first and second code images can be effectively decoded by decoding interpretation information, construction information, error control information, and code direction information stored in the first and/or second code images.
摘要翻译: 提供了用于对作为第一和第二代码图像的组合的混合代码进行解码的方法和装置。 在该方法中,通过接收具有混合码图像的原始图像并从原始图像中去除噪声来获得混合码图像。 接下来,基于预定阈值将混合码图像的像素的颜色,阴影和亮度分成组,将混合码图像分割为第一和第二码图像,并且通过解码第一和第二信息来提取第一和第二信息 和第二代码图像。 可以通过解码存储在第一和/或第二代码图像中的解释信息,构造信息,错误控制信息和代码方向信息来有效地解码第一和第二代码图像。
