Abstract:
1. A method comprising: receiving image data at an image sensor array, wherein the image data comprises a plurality of pixels, wherein the plurality of pixels include at least a first set and a second set of pixels, and wherein each pixel of the plurality of pixels is filtered to represent a single color that is independent of other single color values of the pixel; determining a hash value based upon the first set of pixels, wherein the first set of pixels comprises a first row of the image data and the second set of pixels comprises a second row of the image data, and wherein the second row is subsequent to the first row; adjusting single color values of one or more pixels in the second set of pixels to embed a digital watermark into the second set of pixels, wherein the adjusted single color values are weighted relative to other single color values, and wherein the digital watermark comprises the hash value; and approximating a multi-color value for the one or more pixels in the second set of pixels.
