摘要： An object recognizing apparatus can execute accurate object recognition based on dictionaries each created from a predetermined number of patterns, by computing a similarity between a subspace in each dictionary and a subspace created from input images. In this apparatus, images of a to-be-identified object obtained by an image input unit is expressed in the form of an input subspace by an inter-subspace-angle computing unit. The angles between the input subspace and the subspace of each dictionary stored in a dictionary storing unit is computed. An identifying unit identifies a to-be-identified object based on the angles (the degrees of similarity) computed by the inter-subspace-angle computing unit.

摘要： An image pattern of an object is inputted. An input subspace calculation section calculates an input subspace from the image pattern. A dictionary subspace calculation section calculates a dictionary subspace from a learning pattern of each object. A constraint subspace calculation means calculates a constraint subspace from a plurality of input subspaces previously calculated according to constraints to suppress unnecessary patterns. A projection section projects the input subspace and the dictionary subspace onto the constraint subspace. A recognition section recognizes the object by comparing the projected input subspace with the projected dictionary subspace.

摘要： A security apparatus. A service is supplied to a user while maintaining the security of the service. A person discrimination section discriminates the user to be supplied the service. A user situation decision section decides whether the user is under a situation to use the service. An infringement situation decision section detects whether a non-user intrudes into a use area of the service in order to decide whether the security of the service is infringed. A service control section supplies the service to the user in case the person discrimination section discriminates the user, and controls a supply of the service if the use situation decision section decides the user is not under the situation to use the service or the infringement situation decision section decides that the security of the service is infringed.

摘要： In a person identification apparatus, a normalized face image is used to identify a person. When the face image of the person is input, a face area extraction section extracts the face area from the face image. A feature point extraction section extracts a plurality of candidates of feature points from the face area using a separation filter. A feature point set selection section selects sets of the candidates from the plurality of candidates of feature points according to face structure information. A feature point decision section extracts neighboring patterns of each candidate from the face area for the set of candidates, calculates a similarity value between the neighboring patterns of each candidate and the template pattern, and selects a subset of the candidates having the highest similarity values. A normalization section generates a normalized face image of the face area according to the selected subset of the candidates. A recognition section compares the normalized face image with the registered image to identify the person.

摘要： An image processing apparatus. A camera inputs an image of a face of a person to be recognized. A recognition area detection section generates a difference image between the input image and a predetermined pattern, and detects a recognition area whose value is above a threshold from the input image. An input data generation section converts the recognition area to a predetermined input data. A similarity calculation section calculates a similarity by comparing the predetermined input data with a predetermined dictionary data. A view position of the camera is located lower than a position of the face of the person. A direction of the optical axis of the camera represents an angle of elevation from a horizontal direction.

摘要： An image input unit inputs an image including a user's face area to specify the user's gaze or face direction. A pattern generation unit generates an input pattern that can be compared with each dictionary pattern from the image. A dictionary unit previously stores a plurality of dictionary patterns each of which differently corresponds to the user's gaze or face direction. A pattern comparison unit respectively calculates a similarity degree between the input pattern and each of the dictionary patterns by comparing the input pattern with each of the dictionary patterns. A gaze detection unit detects the user's gaze or face direction based on the similarity degree.
