The present invention discloses a reversible adaptive watermark embedding and removal method based on color statistics. The watermark area of ​​the original image is subjected to histogram statistics according to the color system, and the corresponding complementary color image and the optimal watermark color are obtained by calculation to ensure that the watermark color forms a clear contrast with the color of most pixels in the watermark area. After obtaining the watermark marking code representing the watermark color, the marking code is implanted by using the watermark pixel shifting method to complete the watermark pixel marking and visible watermark embedding. In order to ensure that non-watermark pixels belonging to the color system represented by the watermark marking code will not be identified as watermark pixels and mistakenly removed during the watermark removal process, it is necessary to perform color replacement. Finally, magic matrix steganography is used to write the watermark information into the non-interested area of ​​the host image. When removing, the watermark marking code and other key information are first read to retrieve the watermark pixel, which is then reversely shifted to restore the original color information of the watermark pixel, thereby achieving seamless removal of the visible watermark.

A method of determining the concentration of an analyte in a sample of a body fluid with a mobile device having a camera is disclosed. The camera captures an image of a color reference card and of a reagent test field of an optical test strip having a sample applied to it. A predetermined pixel-based mean tone map correction is applied to the image obtained, which results in a first intensity-corrected image. Local brightness information is derived from the first intensity-corrected image. A mobile device-specific tone map correction is applied to the first intensity-corrected image, taking into account the local brightness information. A second intensity-corrected image is thereby obtained. Analyte concentration is determined based on a color formation reaction of the test field by using the second intensity-corrected image. Optionally, a color correction may be derived and applied to the second intensity-corrected image to obtain an intensity-corrected and color-corrected image.
