Automatic Interpretation of Floor Plans Usingspatial
نویسندگان
چکیده
A system is presented that classiies objects in raw images using statistical pattern recognition and spatial indexing. The system is given a training set containing samples of feature vectors of objects that may be found in the images. This method of classiication was applied to automatic interpretation of oor plans. A number of data structures are suggested for storing the training set. Of these, the adaptive k-d tree was found to be a highly eecient storage mechanism, and provided recognition rates of 98% and higher. Storing the training set as feature ranges per class also gave very high recognition rates, at the cost of a relatively small number of comparisons.

Numerical Evaluation of Progressive Collapse Potential in Reinforced Concrete Buildings with Various Floor Plans Due to Single Column Removal
Progressive collapse is defined as the spread of an initial damage from one member to another, leading to extensive partial or total collapse of the structure. In this research, the potential of progressive collapse due to a sudden removal of vertical load-bearing elements in reinforced concrete buildings structures with different floor plans such as geometrical regular and irregular floor plan...

We have applied an automatic interpretation method of potential data called AN-EUL in unexploded ordnance (UXO) prospective which is indeed a combination of the analytic signal and the Euler deconvolution approaches. The method can be applied for both magnetic and gravity data as well for gradient surveys based upon the concept of the structural index (SI) of a potential anomaly which is relate...
