摘要： The invention provides a method for classifying the motion of an object such as a human being in a moving picture. A template is prepared in advance, which includes the Gabor wavelet expansion coefficients of an object image in a plurality of frames of a video image sequence representing each of a plurality of different reference motions of an object in a moving picture. Then, processing is performed to obtain the Gabor wavelet expansion coefficients of an object image in a plurality of frames of a video image sequence representing an unknown motion of the object. Matching factors are calculated based on the expansion coefficients for the unknown motion and the expansion coefficients for the reference motions in the template, and finally the unknown motion is classified based on the matching factors.

摘要： An encoding method is provided with which users can select picture quality and a quantity of data in multiple stages and with which an image of higher picture quality can be regenerated by scalable selection, i.e., by further adding data to compressed data that can be decoded.

摘要： A method and system for maneuvering a mobile robot are disclosed, which include a mobile robot having a plurality of sensors, including a sensor which detects the presence of an object and a sensor which detects image information related to the object. Utilizing data acquired by the plurality of sensors, elements of the object are determined. A hypothesis expressing the configuration of the object is then generated from the elements interpreted from the data. The hypothesis is generated by referencing a table in which interpretations of data acquired by the plurality of sensors are associated with possible configurations of objects in response to the generated hypothesis, the mobile robot is moved along a path which avoids the object.
