    摘要： In an image forming apparatus, a compression history recording portion stores compression history information in a non-transitory computer-readable information storage medium, wherein the compression history information represents results of accumulation of compression levels through the compression process executed by the data compression portion. A history monitoring portion executes a predetermined improvement process when the compression history information satisfies a predetermined insufficient compression condition.

    摘要： Techniques disclosed herein provide an approach using pixel perturbation to transmit information. In one embodiment, a pixel perturbation engine perturbs pixels of an image to encode meta-information therein. In particular, the perturbation engine may perform controlled perturbation of pixel bits which are unlikely to affect visual quality are perturbed, such as perturbing the least significant bits in one or more channels of a RGB or YUV image. Higher order bits may also be perturbed in color channels such as the blue or UV channels that the human eye is less sensitive to. To mitigate loss of information, the information may be encoded using error correcting codes. After the image having meta-information encoded therein is transmitted to a client device, the meta-information may be recovered and used to determine performance of the virtual desktop infrastructures (VDI) system.

    摘要： Watermark data is converted to watermark coefficients, which may be embedded in an image by converting the image to a frequency domain, embedding the watermark in image coefficients corresponding to medium-frequency components, and converting the modified coefficients to the spatial domain. The watermark data is extracted from the modified image by converting the modified image to a frequency domain, extracting the watermark coefficients from the image coefficients, and determining the watermark data from the watermark coefficients. The watermark data may be truncated image data bits such as truncated least significant data bits. After extraction from the watermark, the truncated image data bits may be combined with data bits representing the original image to increase the bit depth of the image. Watermark data may include audio data portions corresponding to a video frame, reference frames temporally proximate to a video frame, high-frequency content, sensor calibration information, or other image data.
