Abstract
An embodiment of this invention is an image processing device, including: a sectioning unit for sectioning an image into a plurality of sections to be processed; and a classification unit for classifying the plurality of sections to be processed into at least a clarification-processing-adapted area for embedding a latent image into the image, and an obfuscation-processing-adapted area for embedding a digital watermark into the image based on a characteristic of the image.
Claims13
An image processing device, comprising:
- a sectioning device configured to section an image into a plurality of sections to be processed;
- a classification device configured to classify the plurality of sections to be processed into at least a clarification-processing-adapted area for embedding a latent image into the image, and an obfuscation-processing-adapted area for embedding a digital watermark into the image based on a characteristic of the image;
- a latent image embedding device configured to embed the latent image into the clarification-processing-adapted area;
- a digital watermark embedding device configured to embed the digital watermark into the obfuscation-processing-adapted area;
- and
- a clarification processing device configured to determine whether a pixel position is within a remaining area, and on a condition that it is determined that the pixel position is within the remaining area, the clarification processing device is further configured to assign a value to a pixel corresponding to the pixel position, wherein the assigned value corresponds to a pixel value for clarification processing and a pixel value for input image data.
