摘要： A message is embedded into a digital image by forming a digitized version of the message and convolving the digitized message with a random phase carrier to form a scrambled message. The scrambled message is then combined with the digital image to form an embedded message image that is near impossible to extract without knowledge of the formation of the random phase carrier.

摘要： The method of the present invention operates upon the imaging signals from a color filter array image sensor to compress the image signals prior to color interpolation by separating the signals into three color planes. Missing green pixels are recovered through interpolation methods, either by bilinear or other techniques, in order to form color ratio signals long B/G.sub.missing and log R/G.sub.missing which allows for proper interpolation after decompression without color artifacts. Upon playback or reception, an inverse compression is applied and missing green, red and blue pixels are interpolated to provide three full planes of color image data.
摘要翻译：本发明的方法根据来自滤色器阵列图像传感器的成像信号进行操作，以通过将信号分离成三个颜色平面来在彩色插值之前压缩图像信号。通过双线性或其他技术通过插值方法恢复缺少的绿色像素，以便形成颜色比信号长B / Gmissing和对数R / Gmissing，其允许在没有色彩伪像的解压缩之后进行适当的插值。在回放或接收时，应用逆压缩，并且插入缺少的绿色，红色和蓝色像素以提供彩色图像数据的三个完整平面。

摘要： In order to analyze a digital video clip to determine candidate frames for subsequent key frame selection, a camera motion sensor is provided in the camera so that information is provided during image capture regarding camera motion including translation of the scene or camera, or scaling of the scene. The sensor includes an accelerometer or a lens motor sensor. A plurality of video segments is formed based on the global motion estimate and each segment is labeled in accordance with a predetermined series of camera motion classes. Thereafter, key frame candidates are extracted from the labeled segments and a confidence score is computed for each candidate by using rules corresponding to each camera motion class and a rule corresponding to object motion.

摘要： A JPEG2000 compressed image is transcoded to a lower bit-rate or lower resolution, or both, without having to decompress the initial JPEG2000 image and then recompress it to a lower bit-rate and/or resolution. Instead, arithmetic decoding is performed only to the nearest higher bit-rate layer, up to the desired resolution, before performing rate-distortion optimization to produce the transcoded image.

摘要： A method for video filtering of an input video sequence by utilizing joint motion and noise estimation comprises the steps of: (a) generating a motion-compensated video sequence from the input video sequence and a plurality of estimated motion fields; (b) spatiotemporally filtering the motion compensated video sequence, thereby producing a filtered, motion-compensated video sequence; (c) estimating a standard deviation from the difference between the input video sequence and the filtered, motion-compensated video sequence, thereby producing an estimated standard deviation; (d) estimating a scale factor from the difference between the input video sequence and the motion compensated video sequence; and (e) iterating through steps (a) to (d) using the scale factor previously obtained from step (d) to generate the motion-compensated video sequence in step (a) and using the estimated standard deviation previously obtained from step (c) to perform the filtering in step (b) until the value of the noise level approaches the unknown noise of the input video sequence, whereby the noise level is then characterized by a finally determined scale factor and standard deviation.

摘要： A method for selectively adjusting the resolution levels or the quality levels of digital images stored in a memory of a digital camera having a predetermined memory space includes capturing a first image and storing the captured first image at a specific resolution level or quality level. The resolution level or quality level of the stored first image is adjusted based on the available memory space in the digital camera memory so that a subsequent captured image can be stored. A subsequent image is then captured, and the captured subsequent image is stored with the adjusted first image.
