Image Zooming Through Interpolatory Orthonormal Multiwavelets
Zhu Shan-hua · Journal of Chinese Computer Systems · 2009
In view of the advantage of interpolatory orthonormal multiwavelet in the signal decomposition and reconstruction such as the multiresolution analysis coefficients can be represented by the sampled value other than computing the inner product of two functions,the paper makes use of the decomposing and reconstructing method of interpolatory orthonormal multiwavelet to realize the image zooming of better visual effect,i.e.,it makes the reduction preserving some important structure features of the original image well and possessing of consistent edge with the original image, makes the enlargment possessing of high definition, overcomes the shortcomings of the interpolatory method for image zooming. The experimental results and quantitative analysis validated the validity of the decomposing and reconstructing method of interpolatory orthonormal multiwavelet.
