We propose a wavelet reconstruction algorithm based on non-separable MRA In the algorithm we disposed the projection data with two channel wavelet decomposement to obtain the approximate coefficient and the detail coefficient of the image, and then after denoised these coefficient with soft-thresholding, we reconstructed the image though reverse wavelets transform. We used two-dimensional quincunx...
Traditional agricultural knowledge service is based on keyword rather than content, the recall rate and precision rate cannot to be improved. The knowledge representation based on semantic web can truly achieve the semantic-level knowledge service. This paper analyzes the status of agricultural knowledge service system and points out its shortcomings, elaborates semantic web technologies, studies...
We propose a wavelet reconstruction algorithm based on non-separable MRA. In the algorithm we disposed the projection data with two channel wavelet. This algorithm not only has the same local reconstruction characteristic with the algorithm based on separable MRA, but have better image quality and shorter working time.
