Visualization and Verification of Automatic Target Recognition Results Using Combined Range and Optical Imager

Three-dimensional visualization environment for multisensor data analysis, interpretation, and model-based object recognition

Model-based object recognition must solve three-dimensional geometric problems involving the registration of multiple sensors and the spatial relationship of a three-dimensional model to the sensors. Observation and verification of the registration and recognition processes requires display of these geometric relationships. We have developed a prototype software system which allows a user to in...

In vivo dose verification using using an amorphous silicon flat panel-type imager (a-Si EPIDs)

Introduction: Electronic portal imaging devices (EPIDs) could be used to dose verification of radiotherapy treatment plans. In vivo dose verification is performed to reduce differences found between dose delivered to the patient and the prescribed dose. The aim of this study was to perform a fast and efficient technique for the verification of delivered dose to the patient usin...

Fuzzy Clustering Approach Using Data Fusion Theory and its Application To Automatic Isolated Word Recognition

 In this paper, utilization of clustering algorithms for data fusion in decision level is proposed. The results of automatic isolated word recognition, which are derived from speech spectrograph and Linear Predictive Coding (LPC) analysis, are combined with each other by using fuzzy clustering algorithms, especially fuzzy k-means and fuzzy vector quantization. Experimental results show that the...

Toward Target Verification Through 3-D Model-Based Sensor Fusion

Most Automatic Target Recognition (ATR) algorithms operate in 2D image space. Even when using 3D models, these 3D models are typically translated o -line into sets of 2D representations, such as templates, which are then applied to imagery to perform detection, recognition and veri cation. In contrast to this approach, the work reported here takes steps toward direct matching of 3D models to ra...
