摘要： An abnormal action detector is provided for accurately detecting the position of an object together with an abnormal action using a cubic higher-order local auto-correlation feature. The abnormal action detector comprises a computer which generates inter-frame differential data from moving image data, extracts cubic higher-order local auto-correlation feature data on a pixel-by-pixel basis, adds the feature data for pixels within a predetermined range including each of pixels, calculates an index indicative of abnormality of the added feature data with respect to a subspace indicative of a normal action, determines an abnormality when the index is larger than a predetermined value, and outputs the position of a pixel at which the abnormality is determined. The computer further finds a subspace which exhibits a normal action from past feature data in accordance with a principal component analysis approach. The abnormal action detector is capable of determining abnormality on a pixel-by-pixel basis and correctly detecting the position of an object which has shown an abnormal action.

摘要： An abnormal action detecting device and method for detecting an abnormal action from a moving picture. An abnormal action detecting device (11) creates from-to-frame difference data from moving picture data inputted from a video camera (10), extracts feature data from three-dimensional data composed of frame-to-frame difference data by using a stereoscopic high-order local cross-correlation, computes the distance between a partial space based on a main component vector determined by a main component analysis technique from the past feature data and the latest feature data, and judges that an action is abnormal if the distance is greater than a predetermined value. By learning a normal action as a partial space and detecting an abnormal action as a deviation from the normal one, for example, even if several persons are present in the screen, an abnormal action of a person can be detected. The computational complexity is low and the real-time processing is possible.

摘要： A tracing device and a tracing method for realizing a real-time trace of a moving object such as a person from a time-varying image by method of a light processing load, and for learning features through the trace thereby to realize a trace of higher precision. The tracing device divides time-varying data inputted into partial images (in a strip or rectangle shape), and compares the background image containing no tracing object thereby with the current image thereby to extract the divided image having the tracing object. In order to discriminate the tracing object, moreover, the tracing device calculates the color high-level local self-correlated data, from which the features of color and shape can be extracted all at once, and performs the discrimination on the basis of a distance from the featuring data of the tracing object registered. The tracing device updates the background image and the registered featuring data into the latest ones. The features are acquired while tracing the tracing object, and the object is discriminated by utilizing the features so that a strong and highly precise trace can be realized.
