An example method includes receiving a plurality of templates of a plurality of objects, where a template comprises feature values sampled at corresponding points of a two-dimensional grid of points positioned over a particular view of an object and scaled based on a depth of the object at the particular view. The method may further include receiving an image of an environment and determining a matrix representative of the image, where a row of the matrix comprises feature values sampled at a particular point of the two-dimensional grid positioned over one or more locations within the image and scaled based on depths of the one or more locations. The method may additionally include determining at least one similarity vector corresponding to at least one template and using the at least one similarity vector to identify at least one matching template for at least one object located within the image.

A position, behavior state and movement state of a moving object are detected, together with plural categories of track segment region and stationary object regions, using an environment detection section. A presence probability is applied to the detected track segment regions and stationary object regions and a presence probability map is generated, using a map generation section. A moving object position distribution and movement state distribution are generated by a moving object generation section based on the detected moving object position, behavior state and movement state, and recorded on the presence probability map. The moving object position distribution is moved by a position update section based on the moving object movement state distribution. The moved position distribution is changed by a distribution change section based on the presence probabilities of the presence probability map, and a future position distribution of the moving object is predicted on the presence probability map. Consequently, the future position of the moving object can be predicted with good precision under various conditions.

Techniques for secure data synchronization are described. In one or more implementations, techniques may be employed to conserve high cost data storage by storing larger portions of encrypted data in low cost storage, while storing relatively smaller encryption keys in higher cost storage. A device that is granted access to the encryption keys can retrieve the encrypted data from the low cost storage and use the encryption keys to decrypt the encrypted data.

An information processing system provisions a client account for a user to enable a client computer associated with the user to store information in an elastic storage system and to prohibit the client computer, the information processing system, and the elastic storage system from altering and from deleting the stored information during an authorized retention period. Data messages are received from one or more client computers and include information that is required to be stored for the authorized retention period. That information is transmitted via one or more data communications networks to the elastic storage system for storage so that the stored information is non-rewriteable and non-erasable during the authorized retention period. The secure data center receives the retrieved copy and provides it to the user device. The elastic storage system permits deletion, modification, or destruction of the stored information only when a trusted independent third party having predetermined authentication information associated with the client account provides the predetermined authentication information to the elastic storage system.
