A New 3-D Pattern Recognition Technique With Application to Computer Aided Colonoscopy
To utilize CT or MRI images for computer aided diagnosis applications, robust features that represent 3-D image data need to be constructed and subsequently used by a classification method. In this paper, we present a computer aided diagnosis system for early diagnosis of colon cancer. The system extracts features by a new 3-D pattern processing method and processes them using a support vector machine classifier. Our 3-D pattern processing method, called Random Orthogonal Shape Section(ROSS) mimics the radiologist's way of viewing these images and combines information from many random triples of mutually orthogonal sections going through the volume. Another contribution of this paper is a new feedback framework between the classification algorithm and the definition of the features. This framework, called Distinctive Component Analysis combines support vector samples with linear discriminant analysis to map the features of clustered support vectors to a lower dimensional space wh...
