Method and apparatus for a fast (low F/number) computational camera that incorporates two arrays of lenses. The arrays include a lenslet array in front of a photosensor and an objective lens array of two or more lenses. Each lens in the objective lens array captures light from a subject. Each lenslet in the lenslet array captures light from each objective lens and separates the captured light to project microimages corresponding to the objective lenses on a region of the photosensor under the lenslet. Thus, a plurality of microimages are projected onto and captured by the photosensor. The captured microimages may be processed in accordance with the geometry of the objective lenses to align the microimages to generate a final image. One or more other algorithms may be applied to the image data in accordance with radiance information captured by the camera, such as automatic refocusing of an out-of-focus image.

In another embodiment, training examples with non-optimal Lagrange multipliers are paired and then adjusted, until all are optimal.

A network data classifier statistically classifies received data at wire-speed by examining, in part, the payloads of packets in which such data are disposed and without having a priori knowledge of the classification of the data. The network data classifier includes a feature extractor that extract features from the packets it receives.

The network data classifier further includes a statistical classifier that classifies the received data into one or more pre-defined categories using the numerical values representing the features extracted by the feature extractor. The statistical classifier may generate a probability distribution function for each of a multitude of classes for the received data. The data so classified are subsequently be processed by a policy engine. Depending on the policies, different categories may be treated differently.

Systems, methods, and apparatuses for high-speed navigation. The present invention preferably encompasses systems, methods, and apparatuses that provide for autonomous high-speed navigation of terrain by an un-manned robot. By preferably employing a pre-planned route, path, and speed; extensive sensor-based information collection about the local environment; and information about vehicle pose, the robots of the present invention evaluate the relative cost of various potential paths and thus arrive at a path to traverse the environment. The information collection about the local environment allows the robot to evaluate terrain and to identify any obstacles that may be encountered. The robots of the present invention thus employ map-based data fusion in which sensor information is incorporated into a cost map, which is preferably a rectilinear grid aligned with the world coordinate system and is centered on the vehicle. The cost map is a specific map type that represents the traversability of a particular environmental area using a numeric value. The planned path and route provide information that further allows the robot to orient sensors to preferentially scan the areas of the environment where the robot will likely travel, thereby reducing the computational load placed onto the system. The computational ability of the system is further improved by using map-based syntax between various data processing modules of the present invention. By using a common set of carefully defined data types as syntax for communication, it is possible to identify new features for either path or map processing quickly and efficiently.

Disclosed is a method and system that adapts coefficients of taps of a Finite Impulse Response (FIR) filter to increase elimination of Inter-Symbol Interference (ISI) introduced into a digital communications signal due to distortion characteristics caused by a real-world communications channel. In the communications system there is a Finite Impulse Response (FIR) filter. The FIR filter has at least one pre and/or post cursor tap that removes pre and/or post cursor ISI from the signal, respectively. The pre/post cursor taps each have pre/post cursor coefficients, respectively, that adjusts the effect of the pre/post cursor portion of the FIR filter. The FIR filtered signal is transmitted over the channel which distorts the signal due to the changing and/or static distortion characteristics of the channel. The channel distorted signal is received at a receiver that may pass the channel distorted signal through a quantifier/decision system (e.g., a slicer) as the quantifier input signal to quantify the quantifier input signal to one of multiple digital values. The channel distorted signal may be further adjusted by summing the channel distorted signal with the output of a Decision Feedback Equalizer (DFE) filter to create a DFE corrected signal which then becomes the quantifier input signal. An error signal is determined by finding the difference between the scaled quantifier decision and the quantifier input signal. The pre/post cursor coefficient values that adjust the effects of the pre/post cursor taps of the FIR filter are updated as a function of the error signal and at least two quantifier decision values, and update coefficient values, may be sent over a communications back-channel to the FIR filter.

This security level scheme also improves runtime performance by making it unnecessary to check individually-defined permissions in many cases.

The present invention applies a technique, which is characteristic of color images, to embed a digital watermark in a color image and decode the embedded digital watermark. The technique adjusts a color signal transformation matrix by adding or subtracting a digital watermark matrix to or from the color signal transformation matrix in the process of transforming image data of an original color image in an RGB colorimetric system into image data in a YCbCr colorimetric system with the color signal transformation matrix. The digital watermark matrix includes an arbitrary numerical value of real number x, which represents digital watermark information, as an entry thereof and satisfies a condition that a sum of respective entries in each row and in each column is all substantially equal to zero. The technique inversely transforms the image data, which is obtained by the transformation with the adjusted color signal transformation matrix, into the image data in the RGB calorimetric system by means of an inverse color signal transformation matrix. The inversely transformed image has the numerical value of real-number x embedded therein as the digital watermark. The numerical value of real number x is decoded from transformed image data, which is obtained by transforming the original image into color signals in the YCbCr colorimetric system.
