This specific person detection system: identifies, from among the persons recorded in a specific person recording unit, a person who most closely matches a feature value extracted from image data; calculates the degree to which feature values of a plurality of persons extracted from other image data match the identified person; and outputs, as an identification result, information about a person who has a feature value closely matching the identified person, and who is associated with angle information that most closely matches angle information associated with the identified person.

Specific person detection system and specific person detection method

Disclosed is a surveillance image retrieval apparatus capable of generating an image representing a search result that a surveillant can visually confirm, even if a face image used is not suitable for the visual identification of a person. The surveillance image retrieval apparatus includes a surveillance image acquirer, which acquires surveillance images; a feature amount generator, which extracts a face image from the surveillance images and generates the feature amount of the extracted face image; an image feature amount memory for storing a face image, a surveillance image, and other metadata associated with an acquired feature amount; a face image designator, which selects an appropriate face image in accordance with a user's input, and designates the selected face image as a query image for a person search; a similar image searcher for searching the series of surveillance images stored in the image feature amount memory for a face image similar to the designated face image; a presentation image selector, which examines surveillance images that are close to the search result in imaging time, and selects presentation surveillance images that include face images of the same person; and a screen data generator for outputting the presentation surveillance images selected.

Surveillance image retrieval apparatus and surveillance system

Detection of a specific person with a specific person detecting system using surveillance cameras installed in various environments has not been successfully accurate. A monitoring system of the present invention includes an image pickup device capturing images, an updating type specified person detection server receiving captured images, extracting image feature quantities therefrom and storing image feature quantities and provisional person information of unspecified persons and the reliability thereof in real time, and a monitor station with an image searching function capable of searching an image afterward, which are connected via a network. The updating type specified person detection server adds the person information to a specified person list during system operation on the basis of an unspecified person list that is updated.

Person detection system

Disclosed is a similar facial image search system which is less susceptible to bias in search results even when there is a difference in the angle from which a face is photographed. The present invention is provided with: a means for detecting a first face from the inputted search subject image; a means for calculating and a means for recording a feature value of the detected first face; a means for detecting a second face from an inputted key image used for search; a means for calculating the face angle of the second face; a means for determining a synthesis pattern from the calculated face angle; a means for generating a synthetic face image according to the determined synthesis pattern; a means for calculating the feature value of the second face using the generated synthetic face image; a means for searching a database using a plurality of calculated face feature values as a query; and a means for integrating the plurality of the retrieved search results.

Similar image search system

A video processing apparatus obtains information describing the amount of displacement of images in multiple predetermined units (such as video durations) imaged by an imaging apparatus from an image at steady state, which is a reference, and displays the images in the multiple predetermined units in decreasing order of amounts of displacement based on the obtained information describing the amounts of displacement.

Video processing method for reducing the load of viewing

An image data recording and reproducing system comprises an image data input unit, an ID generator generating an ID inserted to image data from the image data input unit, a plurality of image data recorders for recording the image data, and an output unit for outputting the image data recorded into the plurality of image data recorders, wherein each of the plurality of image data recorders has an ID table and an image data storage area, and an ID of the ID table is matched with image data of the image data storage area on the bases of recording position information of the image data.

Recording and reproducing system for image data with recording position information and a recording and reproducing method therefor

An image reproduction function for reproducing effectively reproducing image recorded in a storage device in diversified forms is provided. A moving picture obtained from one image pickup device is recorded in a plurality of systems at different frame rates. The recorded moving picture is formed of a plurality of still picture data. When reproducing the recorded moving picture, the still picture data forming a moving picture of either one of the systems are reproduced according to a time axis serving as reference for reproduction of the recorded moving picture.

Image storage system

In an image recording/reproduction method for recording image information on a recording medium by using a computer, a verify mode is set into the OFF state when recording image information on said recording medium. In addition, use as a write or read region a specified region of the recording medium which is greater than or equal to a unitary data size being handled during error correction processing to be performed when writing or reading image information on or out of said recording medium. Additionally, upon reading of image information from the recording medium, any image information that has experienced read errors will never be read again.
