A system and method for building and / or manipulating a centralized medical image quantitative information database aid in diagnosing diseases, identifying prevalence of diseases, and analyzing market penetration data and efficacy of different drugs. In one embodiment, the diseases are bone-related, such as osteoporosis and osteoarthritis. Subjects' medical images, personal and treatment information are obtained at information collection terminals, for example, at medical and / or dental facilities, and are transferred to a central database, either directly or through a system server. Quantitative information is derived from the medical images, and stored in a central database, associated with subjects' personal and treatment information. Authorized users, such as medical officials and / or pharmaceutical companies, can access the database, either directly or through the central server, to diagnose diseases and perform statistical analysis on the stored data. Decisions can be made regarding marketing of drugs for treating the diseases in question, based on analysis of efficacy, market penetration, and performance of competitive drugs.

This invention relates to portable imaging devices, such as hyperspectral imaging devices, useful for forensic and other analysis, and methods for using these devices.

This invention is directed to an apparatus and method for sensing and detecting a number of physical, biological and chemical characteristics of a person, preferably in connection with the process of verifying the identity of the individual. The apparatus may be employed as part of the check-in procedures at airports, bus stations, train stations, cruise ships and other vessels, as well as other situations where identification verification may be required, e.g. banking transactions and the like.

The present invention relates to a method for the generation of a facial composite from the genetic profile of a DNA-donor. The method comprises the steps of a) subjecting a biological sample to genotyping thereby generating a profile of genetic markers associated to numerical facial descriptors (NFD) for said sample, b) reverse engineer a NFD from the profile of the associated genetic variants and constructing a facial composite from the reverse engineered numerical facial descriptors (NFDs). The present invention also relates to a method for identifying genetic markers and / or combinations of genetic markers that are predictive of the facial characteristics, (predictive facial markers) of a person, said method comprising the steps of: a) capturing images of a group of individual faces; b) performing image analysis on facial images of said group of individual faces thereby extracting phenotypical descriptors of the faces; c) obtaining data on genetic variation from said group of individual and d) performing a genome-wide association study (GWAS) to identify said predictive facial markers.

The present invention is a method and apparatus for drug sample identification, including a scale for weighing a drug sample and an imaging module for capturing digital images of the drug sample, from at least two different visual perspectives simultaneously, and an transmitting the collected data and images, via an interface, to a computer for storage and association with an image database.

The invention relates to a method for footprint image retrieval. The method comprises the following steps: pre-training a model through ImageNet data; adopting the pre-trained model to perform cleaning and expansion preprocessing operation on footprint data, dividing the footprint data into a plurality of data sets with different purposes, adjusting a full connection layer and a classification layer of the model, adopting parameters of the pre-trained model, and using the footprint data sets to perform model retraining; storing the secondarily trained model, removing a classification layer ofthe model, and performing feature extraction on the images in the image library and the retrieval library to form a feature index library; connecting the features extracted by the three models to forma fusion feature, and establishing a fusion feature vector index library; extracting image features in a to-be-retrieved image library in advance, establishing a feature vector library, and when a single footprint image is input, carrying out distance calculation in the retrieval library and the image library, and outputting an image with the highest similarity. The footprint image recognition and retrieval functions are realized.

Systems, methods, and kits are disclosed for collection, labeling and analyzing biological samples containing nucleic acid in conjunction with collecting at least one ridge and valley signature of an individual. Such devices and methods are used in forensic, human identification, access control and screening technologies to rapidly process an individual's identity or determine the identity of an individual.

Systems, devices, and methods for detecting a contaminant on a substrate are discussed herein. Variations of such systems, devices, and methods may include one or snore illumination sources that emit illumination at one or more desired wavelength ranges to illuminate one or more areas on the substrate; where the desired wavelength range is one that is absorbed by the contaminant while causing the substrate to fluoresce. Such fluorescence may be detected with a visible-spectrum detector, which will also detect the contaminant as a darker contrast area against the fluorescence. In some variations, an illumination source includes a broad-spectrum light source and a waveband filtering device that filters all but the desired illumination waveband out of the broad-spectrum light generated by the broad-spectrum light source.

A method for developing latent fingerprints includes placing an apparatus in an area having one or more objects. The apparatus has a breakable capsule containing a cyanoacrylate monomer disposed within an internal chamber of a housing containing a cyanoacrylate catalyst and being adapted for emitting vapors. The housing is impregnated with the cyanoacrylate catalyst or has a layer of cyanoacrylate catalyst on a portion of its interior surface. The apparatus optionally has a breakable capsule breaking mechanism for assisting a user in breaking the breakable capsule within the housing. The user breaks the breakable capsule, causing the cyanoacrylate monomer spilling from the breakable capsule to react with the cyanoacrylate catalyst contained in the housing to create vapor fumes. The vapor fumes contact an object being tested to reveal any latent fingerprints on the object.

A server analyzes feature information including a whole body and a face of a person reflected in each of video images from a plurality of monitoring cameras and stores a whole body image and a face image as an analysis result. In response to designation of the whole body image and the face image of a person of interest, a client terminal sends a request for execution of each of first collation processing and second collation processing to the server. When a person matching at least one of the whole body image and the face image of the person of interest is specified by at least one of the first collation processing and the second collation processing, the server sends an alarm notification to the client terminal that the person of interest is found to the client terminal.
