Abstract: Techniques for sharing data among a plurality of networked devices, also referred to network nodes, are discussed. To best use an available uploading bandwidth of a device sharing data with a receiving device, a portion of the data is uploaded within the available uploading bandwidth, and another portion of the data is uploaded from another device locally caching the same data. To satisfy the minimum transmission rate of the data to the receiving device, both portions of the data are concurrently uploaded from the two devices to the receiving device. In reference to a predetermined minimum uploading bandwidth and the available uploading bandwidth, the two portions of data are interleaved and must be reassembled to recover the data for consumption in the receiving device. A size of the first portion of the data is determined by a server in view of the available uploading bandwidth a designated supplying box has.

Abstract: An imaging system comprises a rolling-reset imager that forms an electronic image of an object, a light source illuminating the object with pulsed light, and a bandpass optical filter disposed between the object and the rolling-reset imager. The pulsed light has an illumination frequency spectrum and an illumination pulse width defining an effective exposure time for forming the image of the object. The bandpass optical filter has a frequency pass band permitting transmission of a significant portion of the illumination frequency spectrum while at least approximately inhibiting transmission of at least some light having frequencies outside the illumination frequency band. An imaging method illuminates an object with light in a given frequency range, so that the illumination light reflects from the object along with background light. The method filters the reflected light so as to attenuate at least some of the background light by a greater attenuation factor than the illumination light.

Abstract: A digital camera has a signal processor, a high-frequency detector, a sampling processor, and a compression processor. The signal processor generates luminance and color difference data on the basis of image-pixel signals read from an image sensor. The high-frequency detector detects high-frequency components in the color difference data. The sampling processor carries out a sampling process to the luminance and color difference data in accordance with a given ratio of sampling frequencies. Then, the compression processor compresses the sampled luminance and color difference data. When there is a relatively low number of high-frequency components in the color difference data, the sampling processor samples the color difference data with a low sampling frequency.

Abstract: Methods for pre-processing video sequences prior to compression to provide data reduction of the video sequence. Also, after compression of the pre-processed video sequence, the bit rate of the pre-processed and compressed video sequence will be lower than the bit rate of the video sequence after compression but without pre-processing. Pre-processing may include spatial anisotropic diffusion filtering such as Perona-Malik filtering, Fallah-Ford filtering, or omni-directional filtering that extends Perona-Malik filtering to perform filtering in at least one diagonal direction. Pre-processing may also include performing filtering differently on a foreground region than on a background region of a video frame. This method includes identifying pixel locations having pixel values matching characteristics of human skin and determining a bounding shape for each contiguous grouping of matching pixel locations.

Abstract: A two-dimensional (2-D) machine-vision safety method and apparatus performs high-integrity, high efficiency machine vision. The system digitally filters a configurable number of time-sequenced camera images of a viewed area to create a filtered image. Objects within view in a training phase are detected and compared to objects detected in a runtime phase. Each new image is then compared to the previously created model and a pixel-oriented difference image is calculated. The difference image is then processed for segmentation features attributable to an intruder object. Alarm conditions are determined from threshold parameters related to location of the intruder objects. For segmentation results that exceed a predetermined threshold, an alarm condition is set. Setup parameters are automatically generated by analysis of distinctively marked physical boundaries in an image.

Contour convergence to the contour of the extraction target is effected on the basis of the set initial contour. As the other frame, frames preceding and subsequent to the selected frame with respect to time can be set.
