In this paper, a new method of saliency-based traffic sign detection is presented. On the basis of the visual attention mechanism model, edge and color information are extracted as early visual features, and each feature is computed and normalized to obtain feature maps, conspicuity maps and the saliency map. Then the candidate regions containing traffic signs are determined with self-organizing map...
This paper proposes a method, which makes use of the band-pass property of the wavelet transform, combining the wavelet analysis with autocorrelation function to extract melody characters from the humming signal. After the wavelet transform, the humming signal is weighed, and then combined with auto-correlation function for signal analysis. The weighted factors in the design, gives full consideration...
In this paper, we introduced the overview of short text research and the short text classification firstly. On the foundation of several common used classic text classification algorithms, mainly according to the major feature extraction methods, the short text classification based on statistics and rules is proposed. Experiments show that this algorithm has better performance than other algorithms...
Nowadays, soft X-Ray microscopy technology is one of the hottest methods that researches and observes the biological samples of natural state, whose resolution is higher than the imaging drawing of optical microscope and near to the imaging drawing of electron microscope. The technology is simple for the preparation of biological sample, which needs only ultramicrocut. And the working procedure of...
In the past few years, as the volume of junk information on the internet has grown tremendously, researchers' begun to handle this issue. In this paper, an algorithm, called DCM (Discriminative Category Matching) algorithm is employed to do the content based information filtering system design. To our knowledge, the algorithm is the first introduced into filtering information on the internet. System...
