Gun Shot Detector
A gunshot detection system provides an audio and visual surveillance system, embodied within a Gunshot Detector (GSD) attached to a building's walls and ceilings and a Firearm Event Detector (FED) worn on a person's outer clothing. In both embodiments, the system of the invention detects the physical signatures of a firearm discharge, specifically sound from a muzzle blast and light from a muzzle flash. The system would be linked to a software program and / or electronic transducer(s) and / or microprocessor(s) and / or electronic Logic Circuitry (using algorithms, logic gates) that would apply one or more identification algorithms to distinguish firearm discharge from other signals. Either embodiment may be linked to an emergency notification system or to a “Guardian Barrier System” (GBS) wherein a facility or premises, for example a school, is equipped with electromagnetically releasable and electromagnetically lockable doors such that facility or premises may be automatically locked down.

An improved solution for detecting events in video is provided, in which a region of interest within a series of video images of the video is monitored. An object at least partially visible within the series of video images is tracked and a fiducial region of the object is identified. The fiducial region is one or more points and / or area(s) of the object, which are relevant in determining whether an alert should be generated. The fiducial region is monitored with respect to the region of interest and a restricted behavior. When the restricted behavior is detected with respect to the region of interest, an alert is generated.

ActiveUS7113185B2Simple geometrySimple and efficient to and analyzeImage enhancementImage analysisVideo sequenceVisual perception
A simplified general model and an associated estimation algorithm is provided for modeling visual data such as a video sequence. Specifically, images or frames in a video sequence are represented as collections of flat moving objects that change their appearance and shape over time, and can occlude each other over time. A statistical generative model is defined for generating such visual data where parameters such as appearance bit maps and noise, shape bit-maps and variability in shape, etc., are known. Further, when unknown, these parameters are estimated from visual data without prior pre-processing by using a maximization algorithm. By parameter estimation and inference in the model, visual data is segmented into components which facilitates sophisticated applications in video or image editing, such as, for example, object removal or insertion, tracking and visual surveillance, video browsing, photo organization, video compositing, etc.

System and method for fast on-line learning of transformed hidden Markov models
InactiveUS20050047646A1High marginal probabilityReduce decreaseRecord information storageUsing detectable carrier informationBatch processingLatent image
A fast variational on-line learning technique for training a transformed hidden Markov model. A simplified general model and an associated estimation algorithm is provided for modeling visual data such as a video sequence. Specifically, once the model has been initialized, an expectation-maximization (“EM”) algorithm is used to learn the one or more object class models, so that the video sequence has high marginal probability under the model. In the expectation step (the “E-Step”), the model parameters are assumed to be correct, and for an input image, probabilistic inference is used to fill in the values of the unobserved or hidden variables, e.g., the object class and appearance. In one embodiment of the invention, a Viterbi algorithm and a latent image is employed for this purpose. In the maximization step (the “M-Step”), the model parameters are adjusted using the values of the unobserved variables calculated in the previous E-step. Instead of using batch processing typically used in EM processing, the system and method according to the invention employs an on-line algorithm that passes through the data only once and which introduces new classes as the new data is observed is proposed. By parameter estimation and inference in the model, visual data is segmented into components which facilitates sophisticated applications in video or image editing, such as, for example, object removal or insertion, tracking and visual surveillance, video browsing, photo organization, video compositing, and meta data creation.

Method for detecting exception target behavior in intelligent vision monitoring
The invention discloses a method for detecting abnormal target behavior in intelligent visual surveillance. The method includes two processes, namely, target behavior learning and target behavior detection. The target behavior obtains the abnormal threshold value Epsilon of every sub-track distribution mode and the abnormal threshold value Epsilon of every track distribution mode of target trajectory which describes occurred target behavior; the target detecting processes calculate the distance from the target trajectory which describes the target behavior to be measured to every sub-track distribution mode and every track distribution mode so as to compare the distance with the abnormal threshold value and judge whether the target behavior is abnormal. The method uses the local and integral behavior modes of self-organizing map network acquisition target respectively, which can detect not only the integral abnormal behavior of a target, but also the local abnormal behavior of the target in moving process.
