for many years, researchers have studied high accuracy methods for recognizing the handwriting and achieved many significant improvements. however, an issue that has rarely been studied is the speed of these methods. considering the computer hardware limitations, it is necessary for these methods to run in high speed. one of the methods to increase the processing speed is to use the computer pa...

The availability of low-cost computational power is enabling the development of increasingly sophisticated CAD software. Automation of design and manufacturing activities poses many difficult computational problems-significant among them is how to develop interactive systems that enable designers to explore and experiment with alternative ideas. As more downstream manufacturing activities are c...

In this paper we propose a face recognition system based on local features. Interesting feature points in the face image are located by Gabor filters, which gives us an automatic system that is not dependent on accurate detection of facial features. The feature points are typically located at positions with high information content (such as facial features), and at each of these positions we ex...

Various approaches have been demonstrated for the automatic interpretation of crystallographic data in terms of atomic models. The use of a masked Fourier-based search function has some benefits for this task. The application and optimization of this procedure is discussed in detail. The search function also acquires a statistical significance when used with an appropriate electron-density targ...

speech emotion can add more information to speech in comparison to available textual information. however, it will also lead to some problems in speech recognition process. in a previous study, we depicted the substantial changes of speech parameters caused by speech emotion. therefore, in order to improve emotional speech recognition rate, in a first step, the effects of emotion on speech par...

The algorithms for the reduction of the number of features without degrading the performance of pattern recognition systems play an important role in real applications. In this work a new algorithm for feature selection is proposed. This algorithm is based on the Discriminative Feature Extraction (DFE) technique and has been applied to speech recognition. The experimental results show that the ...
