Method For Reducing Blocking Artifacts In Digital Images

View page
US Patent:
6393061, May 21, 2002
Filed:
May 15, 1998
Appl. No.:
09/079769
Inventors:
Yuri Owechko - Newbury Park CA
Assignee:
Hughes Electronics Corporation - El Segundo CA
International Classification:
H04N 712
US Classification:
37524029
Abstract:
A method for reducing blocking artifacts in digital images is disclosed. An original image is segmented into pixel blocks and mapped into a set of images associated with a predetermined compression format to produce a second image. Pixel block border pixel values in the second image are compared and adaptively adjusted to produce a third image with reduced border discontinuities. Non-border pixels within the third image are replaced with pixels from the original image to produce a fourth image that maintains fidelity to the original image. A blockiness metric may be used to repeat the mapping, comparing, adjusting, and replacing steps until blockiness crosses a predetermined level.

Classification Method And Apparatus Based On Boosting And Pruning Of Multiple Classifiers

View page
US Patent:
6456991, Sep 24, 2002
Filed:
Sep 1, 1999
Appl. No.:
09/388858
Inventors:
Narayan Srinivasa - Thousand Oaks CA
Yuri Owechko - Newbury Park CA
Assignee:
HRL Laboratories, LLC - Malibu CA
International Classification:
G06N 302
US Classification:
706 20, 706 16, 706 25, 704 9
Abstract:
A boosting and pruning system and method for utilizing a plurality of neural networks, preferably those based on adaptive resonance theory (ART), in order to increase pattern classification accuracy is presented. The method utilizes a plurality of N randomly ordered copies of the input data, which is passed to a plurality of sets of booster networks. Each of the plurality of N randomly ordered copies of the input data is divided into a plurality of portions, preferably with an equal allocation of the data corresponding to each class for which recognition is desired. The plurality of portions is used to train the set of booster networks. The rules generated by the set of booster networks are then pruned in an intra-booster pruning step, which uses a pair-wise Fuzzy AND operation to determine rule overlap and to eliminate rules which are sufficiently similar. This process results in a set of intra-booster pruned booster networks. A similar pruning process is applied in an inter-booster pruning process, which eliminates rules from the intra-booster pruned networks with sufficient overlap.

Fuzzy Expert System For Interpretable Rule Extraction From Neural Networks

View page
US Patent:
6564198, May 13, 2003
Filed:
Feb 16, 2000
Appl. No.:
09/504641
Inventors:
Srinivasa Narayan - Moorpark CA
Yuri Owechko - Newbury Park CA
Assignee:
HRL Laboratories, LLC - Malibu CA
International Classification:
G06F 1700
US Classification:
706 60
Abstract:
An method and apparatus for extracting an interpretable, meaningful, and concise rule set from neural networks is presented. The method involves adjustment of gain parameter, and the threshold, T for the sigmoid activation function of the interactive-or operator used in the extraction/development of a rule set from an artificial neural network. A multi-stage procedure involving coarse and fine adjustment is used in order to constrain the range of the antecedents of the extracted rules to the range of values of the inputs to the artificial neural network. Furthermore, the consequents of the extracted rules are provided based on degree of membership such that they are easily understandable by human beings. The method disclosed may be applied to any pattern recognition task, and is particularly useful in applications such as vehicle occupant sensing and recognition, object recognition, gesture recognition, and facial pattern recognition, among others.

Computer Vision Method And Apparatus For Imaging Sensors For Recognizing And Tracking Occupants In Fixed Environments Under Variable Illumination

View page
US Patent:
6608910, Aug 19, 2003
Filed:
Sep 2, 1999
Appl. No.:
09/389874
Inventors:
Narayan Srinivasa - Moorpark CA
Yuri Owechko - Newbury Park CA
Assignee:
HRL Laboratories, LLC - Malibu CA
International Classification:
G06K 900
US Classification:
382100, 356375
Abstract:
An computer vision method and system for recognizing and tracking occupants in a fixed space under variable illumination. The system utilizes a camera to capture an initial image of the unoccupied fixed space and subsequently captures images of the occupied fixed space. The edge maps of the current estimate of the unoccupied fixed space including illumination variations and the occupied fixed space are computed. The edge map of the current estimate of the unoccupied fixed space is then subtracted from the edge map of the occupied fixed space to yield a residual edge map, which is then processed to extract the image of the occupant. At least one equivalent rectangle is then computed from the two-dimensional moments of the image of the occupant. The equivalent rectangles are then used to determine the occupant type and position and to track changes in real-time. This method and system is generally designed for use with automobile safety systems such as âsmartâ airbags.

Sensor Fusion Architecture For Vision-Based Occupant Detection

View page
US Patent:
6801662, Oct 5, 2004
Filed:
Oct 10, 2000
Appl. No.:
09/685235
Inventors:
Yuri Owechko - Newbury Park CA
Narayan Srinivasa - Moorpark CA
Swarup S. Medasani - Thousand Oaks CA
Riccardo Boscolo - Culver City CA
Assignee:
HRL Laboratories, LLC - Malibu CA
International Classification:
G06K 962
US Classification:
382224, 382103, 382104, 382284, 701 45
Abstract:
A vision-based system for automatically detecting the type of object within a specified area, such as the type of occupant within a vehicle. Determination of the type of occupant can then be used to determine whether an airbag deployment system should be enabled or not. The system extracts different features from images captured by image sensors. These features are then processed by classification algorithms to produce occupant class confidences for various occupant types. The occupant class confidences are then fused and processed to determine the type of occupant. In a preferred embodiment, image features derived from image edges, motion, and range are used. Classification algorithms may be implemented by using trained C5 decision trees, trained Nonlinear Discriminant Analysis networks, Hausdorff template matching and trained Fuzzy Aggregate Networks. In an exemplary embodiment, class confidences are provided for a rear-facing infant seat, a front-facing infant seat, an adult out of position, and an adult in a normal or twisted position. Fusion of these class confidences derived from multiple image features increases the accuracy of the system and provides for correct determination of an airbag deployment decision.

An information extractor is adapted to extract occurrences of prospective representations of dimensions of application specific multidimensional information and occurrences of non-application specific multidimensional information from the member documents. Also, an encoder is adapted to encode the occurrences of prospective dimensions of application specific and non-application specific multidimensional information contained in member documents. A member document identifier determines document formatting and decides whether to proceed with further processing. An information verification unit optionally verifies the extraction of application specific multidimensional information from the member documents.
