摘要： A cell phone is disclosed for acquiring information to be transmitted to a receiving facility and for transmitting such thereto. A capture device captures information from an external source. A processor is provided for associating with the captured information a representation of the date and time of the capture of the information, such that the representation of the date and time information in association with the captured information forms augmented captured information. The processor also places the augmented captured information in association with subscriber information in a transmission of the augmented captured information to a receiving facility requiring such subscriber information. A transmitter transmits the transmission including the augmented captured information and the subscriber information to the receiving facility. An encryptor encrypts the augmented captured information with a symmetrical encryption algorithm to provide encrypted augmented captured information in the transmission with the subscriber information.

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.

The method for picture-based barcode decoding includes the following steps: capturing all or part of a picture as a captured image; normalizing the captured image for generating a transformed image; calculating a mean color value of a plurality of blocks of the transformed image for generating a decoded data; performing an inverse error correction on the decoded data for generating an original data bitstream; transforming the original data bitstream into an original data; and outputting the original data with an output device.

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.
摘要翻译：本文公开的技术提供了使用像素扰动来发送信息的方法。在一个实施例中，像素扰动引擎扰乱图像的像素以在其中编码元信息。特别地，扰动引擎可以执行不受影响视觉质量的像素位的受控扰动，例如扰乱RGB或YUV图像的一个或多个通道中的最低有效位。颜色通道也可能会受到较高阶位的影响，例如人眼不太敏感的蓝色或紫外线通道。为了减轻信息丢失，可以使用纠错码对信息进行编码。在将其中编码的元信息的图像发送到客户端设备之后，元信息可以被恢复并用于确定虚拟桌面基础设施（VDI）系统的性能。
