A system comprises an encoder configured to compress attribute information for a point cloud and/or a decoder configured to decompress compressed attribute information for the point cloud. Attribute values for at least one starting point are included in a compressed attribute information file and attribute correction values used to correct predicted attribute values are included in the compressed attribute information file. Attribute values are predicted based, at least in part, on attribute values of neighboring points and distances between a particular point for whom an attribute value is being predicted and the neighboring points. The predicted attribute values are compared to attribute values of a point cloud prior to compression to determine attribute correction values. A decoder follows a similar prediction process as an encoder and corrects predicted values using attribute correction values included in a compressed attribute information file.

The invention discloses an automatic classification method of airborne laser radar point cloud data, belonging to the technical field of airborne laser radar. In order to improve the efficiency and the precision of the automatic classification of the point cloud data, the method comprises the steps of: firstly, splitting the point cloud data; secondly, counting the each attribute information of splitting segments; and judging the category of the splitting segments according to the spatial space relationship among the splitting segments and the attribute information of the segments.

A of automatically classifying alerts issued by intrusion detection sensors (11a, 11b, 11c) of an information security system (1) for producing collated alerts, each alert being defined by a plurality of qualitative attributes (a₁, . . . , a_n) belonging to a plurality of attribute domains (A1, . . . , An). Attributes belonging to each attribute domain are organized into a hierarchical structure. For each alert issued by the intrusion detection sensors (11a, 11b, 11c), a trellis specific to that alert is constructed by generalizing each alert in accordance with each of its attributes and at all the levels of the hierarchical structure. Each specific trellis is iteratively merged into a general trellis. Collated alerts in the general trellis are identified by selecting the alerts that are simultaneously the most pertinent and the most general. The collated alerts are supplied to an output unit (23) of an alert management system (13).

The present invention relates to information processing apparatus and methods and, more particularly, to information processing apparatus and methods making use of a 3D model (3D shape) prepared by 3D-CAD. For adding attribute information (distances, angles, hole diameters, dimensional tolerances, etc.) to the 3D model, it becomes harder to recognize the shape of the 3D model and the attribute information on a display screen with increase in the added information. Thus each visual axis direction (attribute arrangement plane) is set for the 3D model prepared and attribute information is inputted so as to be opposed to the attribute arrangement plane thus set. When the set attribute arrangement plane is then specified, the opposed attribute information, together with the shape of the 3D model set, is displayed on the display screen. Names of attribute arrangement planes are arranged so as to avoid overlap thereof on the display screen, thereby suppressing deterioration of visibility. Each attribute arrangement plane has a frame and the attribute information is placed within the frame.
