    摘要: A method and apparatus for analyzing risk associated with published logs are described. In one embodiment, the method comprises accessing a first log published to one or more logs. In one embodiment, the method may also comprise estimating a probability that an entry within the first log will not be verifiable from a second entry selected from one o the one or more logs.

    摘要: A method and apparatus is described for segmenting an image, for adaptively scaling an image, and for automatically scaling and cropping an image based on codestream headers data. In one embodiment, a file that can provide a header that contains multi-scale entropy distribution information on blocks of an image is received. For each block, the block is assigned to a scale from a set of scales that maximizes a cost function. The cost function is a product of a total likelihood and a prior. The total likelihood is a product of likelihoods of the blocks. The image is segmented by grouping together blocks that have been assigned equivalent scales. In one embodiment, the file represents an image in JPEG 2000 format.

    摘要: A method and apparatus for image processing is described. In one embodiment, the method comprises accessing header data from a multi-resolution codestream of compressed data of a first document image, deriving one or more retrieval attributes from the header information, and performing image analysis between the first document image and a second document image based on the one or more retrieval attributes.

    摘要: A motion sensor is mounted within a camera, and measures motion data such as translation, rotation, and zoom. The motion data is then associated with the video frame data captured by the camera. In some embodiments, the motion data is used to remove jitter in the frame data due to camera movement, and in some embodiments, the motion data is used to remove global motion from frame data before compression. Since the motion data is kept with the video frame data, the motion data is available during decompression of the video frames.
