Abstract: A code conversion device for image information for generating an image code which is unique to the image information from the image information, the code conversion device for image information includes a processor and a memory, wherein the memory contains instructions for causing the processor to perform operations of: converting acquired raw image information into a plurality of pieces of developed image information; extracting each piece of feature information, from each of the plurality of pieces of developed image information by performing a self-organization processing using a probability scale on each of the plurality of pieces of developed image information; and quantifying a plurality of pieces of feature information and generating an image code.

Abstract: In the field of information processing, the invention is related to an information embedded code, a method for generating an information embedded code, a method for embedding the code, and a method for reading the same. The invention is characterized by enabling distinguishing of product authenticity under natural light and using a standard mobile phone, and solves the problem of unifying authenticity identification for a general consumer and authenticity identification of an expert. An information embedded code is configured from a dot pattern enabling multi bits information to be written on the basis of the geometric placement or physical placement of an information dot relative to a specified reference dot. By adapting a new type of vertically-horizontally integrated virtual reference line the information embedded code according to this invention is capable of increasing the efficiency of code information recording.

Abstract: An image code conversion device for image information and its method are provided. By extracting a plurality of features of an image based on raw image information taken by an image reading device and converting the features into a unique code, the image code conversion device for image information and its method can stably convert the same image into the same image code. Raw image information acquired by an image reading device is converted into a plurality of pieces of developed image information on the basis of geometrical or physical factors. From the plurality of developed image information, feature information is quantified by a self-organization processing based on a probability scale. The quantified feature information is converted into a digital code. Accordingly, a unique image code corresponding to the raw image information is generated.
