Implementation for Super Resolution--An Improved Image Interpolation Based on Wavelet
Due to some inner and outer reseasons of image systerm
images which obtained by some sensors will be degraded unavoidably. As an effective technique to enhance the resolution and quality of images
Super-resolution technique is becoming a hot topic
which plays an important role in numerous applications of image processing and communication such as HDTV
target recognition
medical image processing and so on. The main purpose of this paper is to present a feasible super resolution to improve the resolution and quality of images. A lot of approaches have been developed including interpolative method
which is a most simple and direct method of super resolution. Some classicial interpolative methods will be introduced and analysised briefly in the first part of this paper
and then wavelet thansform is shortly described in order to provide the convenience for obtaining a new interpolative scheme. Considering the powerful advantages of Bézier surface method
which is very precision and can be implemented fast
the novel method combined wavlet transform with Bézier surface is described in this paper. This method has two merits at least
first it overcomes the shortcoming of traditional methods which are usually cause the degrading for image details
at the same time
this method is not complex due to the fast implementation of the Bézier surface interpolation. The experimental results show the computational feasibility of this method.
