Principle component analysis (PCA) was used to extract components from the solid-state nuclear magnetic resonance (NMR) spectra of bacterial cellulose (BC). Polymers such as cellulose have several domain structures, and their structure and dynamics are reflected in the variety of solid-state spectra derived from different parameters. The complexity of the obtained spectra makes the analysis of ...

The CSU Face Identification Evaluation System provides standard face recognition algorithms and standard statistical methods for comparing face recognition algorithms. The system includes standardized image pre-processing software, three distinct face recognition algorithms, analysis software to study algorithm performance, and Unix shell scripts to run standard experiments. All code is written...

Object Detection with Vector Quantized Binary Features John Krumm Intelligent Systems & Robotics Center Sandia National Laboratories Albuquerque, NM 87185 [email protected] Abstract This paper presents a new algorithm for detecting objects in images, one of the fundamental tasks of computer vision. The algorithm extends the representational efficiency of eigenimage methods to binary features, ...

in the present study, 45 rainwater samples were collected from february to december 2012 on event basis in east bokaro coal mining environment. physico-chemical and major ionic compositions of rainwater samples as well as water soluble major ion composition were analyzed to employ principle component analysis for source identification. the average ph value was recorded 6.1 and varied from 5.1 t...

Abstract The flight control component is a complex embedded computer system integrating navigation solution, calculation and rudder calculation, which the core of intelligent ammunition system. Through analysis comparison hardware interface operational capability requirements components different guidance systems, results show that key factor affecting overall structure components, then summari...

In this paper, three baseline face recognition algorithms are evaluated on the CAS-PEAL-R1 face database which is publicly released from a large-scale Chinese face database: CAS-PEAL. The main objectives of the baseline evaluations are to 1) elementarily assess the difficulty of the database for face recognition algorithms, 2) provide an example evaluation protocol on the database, and 3) ident...
