An adaptive image tone mapping curve based on perceptual preference guidelines is generated as a sigmoidal function, in which the sigmoidal function parameters (slope and shift) are determined by original image statistics. Tone curves generated for different images each have a smooth sigmoidal shape, so that the tone mapping process does not change the image histogram shape drastically. The sigmoidal function has the form: <math-cwu id="MATH-US-00001"> <number>1< / number> t it ( x ) = 100 1 + exp it ( - alpha it ( x / 100 - beta ) ) , <mathematica-file id="MATHEMATICA-00001" file="US20020171852A1-20021121-M00001.NB" / > <image id="EMI-M00001" wi="216.027" he="18.96615" file="US20020171852A1-20021121-M00001.TIF" imf="TIFF" ti="MF" / > < / math-cwu> where alpha is the slope parameter and beta is the shift parameter. The input value x in the sigmoidal function varies in the range [0, 100], because the tone curve is generated on an L* scale, which has values from 0 to 100. The sigmoidal tone curve calculation can be implemented efficiently using simple arithmetic operations by pre-calculating and storing various factors used in the calculation of alpha and beta and by pre-generating a pair of fixed tone curves with two extreme slopes and interpolating between the curves.

A software-based electronic data discovery tool which accesses multiple electronic archives; copies files and their meta-data into a common repository; vertically de-duplicates and tags the files; horizontally de-duplicates and tags the files; filters and tags the files against a one or more sets of predetermined compliance and privileged criteria identified by one or more parties associated with a specific electronic data discovery procedure; profiles and tags select results; and produces a variety of reports and excerpts. Production is at least one of printing on paper, transferring to magnetic media, or other processes.

The invention relates to a method for automatic recognition and stage compression of medical image regions of interest based on an artificial neural network. Medical image files in a digital diagnostic system are generally larger, and due to the limitation by factors of bandwidth and the like, the transmission speed is low, the effect is not good, and the diagnosis quality is influenced. By the method, medical digital images are subjected to noise elimination, the tissue outline of a human body is recognized, tissue images are subjected to multiple times of overlay operation, image features of the regions of interest are strengthened, feature values are extracted, classification is performed by using an artificial neural network method, the regions of interest and corresponding levels are determined, and tagged image file format (TIFF) images are generated in different compression modes according to different levels of the regions of interest and non-regions of interest. By the method, the medical image files are greatly lessened, the transmission speed is increased, and effective necessary information used for diagnosis and treatment in the images is kept, so the method facilitates the reading of doctors, and can be applied to the digital diagnostic system and a remote medical system, and improve the diagnosis and treatment efficiency and effect.

The present invention provides methods of improving GNSS receivers' satellite signal acquisition and TIFF performances by taking advantage of SBAS signals. Due to a SBAS satellite's geostationary position and typically strong signal, the SBAS satellite signal can be acquired more quickly than a GPS satellite signal. Once a SBAS satellite signal is acquired the Doppler frequency search uncertainty may be reduced for remaining GNSS satellites which are to be acquired. Furthermore, a satellite search list may be optimized to search for satellites close to the line of sight (LOS) of the SBAS satellite for which a signal has been acquired, in receiver “warm” and “hot” start modes. Moreover, since a SBAS signal sub-frame is only one second long, which is shorter than six seconds for a GPS signal sub-frame, synchronization of the SBAS signal sub-frame may be achieved faster than for GPS signals. With aided time information, a receiver may compute the absolute time of week (TOW) from a sub-frame synchronized SBAS signal. Therefore, without necessarily waiting for TOW to be decoded from a GPS signal and with TOW extracted from a SBAS signal, a receiver can achieve better TTFF performance.
