The high computational complexity and great memory requirement prevent the SIFT algorithm from being processed realtimely. The block-parallel SIFT algorithm with boundary extension adopted by existing researches suffers from redundant storages or extra communications to process the boundaries of partitions. The block-parallel SIFT algorithm without boundary extension (pSIFT-noBE) can spontaneously...
Multi-sensors information fusion breaches the localization of single sensor information expression, eliminates redundancy and inconsistency among sensors' data, so it is propitious to judgment and decision-making. This paper uses D-S evidential theory to fuse information of 12 sensors which are installed on power driveline of a certain vehicle. This method is proved to be effective to reduce the uncertainty...
In this paper, it expounded in detail the principle of energy spectrum analysis based on Discrete Wavelet Transform and Multi-resolution Analysis. In the aspect of study on feature extraction method, with investigating the feature of impact factor in vibration signals and considering the non-placidity and nonlinear of vibration diagnosis signals, this paper imported wavelet analysis and fractal theory...
Owing to the broad application value of audio watermarking in remote transmission and mobile extraction, it is very important to study watermarking approaches against A/D and D/A conversion. Based on wavelet decomposition and cepstrum technology, an audio watermarking algorithm is proposed where the low-frequency wavelet coefficients are chosen for cepstrum transforming. Then, the obtained cepstrum...
At present, using focused crawler becomes a way to seek the needed information. The main characteristic of a focused web crawler is to select and retrieve only relevant web pages in each crawling process. In this paper, we propose a learnable algorithm that combines link analysis with web content in order to retrieve specific web documents, and it can predict the next URL through learning. The algorithm...
