Comparison Analysis Based on the Cubic Spline Wavelet and Daubechies Wavelet of Harmonic Balance Method

Cubic Spline Wavelet Bases of Sobolev Spaces and Multilevel Intorpolation

In this paper, it is constructed that a semi-orthogonal cubic spline wavelet basis of homogeneous Sobolev space H 2 0 (I), which turns out to be a basis of continuous space C 0 (I). Meanwhile, the orthogonal projections on the wavelet subspaces in H 2 0 (I) are extended to the interpolating operators on the corresponding wavelet subspaces in C 0 (I). It is also given that a fast discrete wavele...

Wavelet Based Image Compression using Daubechies Filters

Digitized images have replaced analog images as photographs or x-rays in many different fields. In their raw form, digital images require a tremendous memory capacity for storage and large amount of bandwidth for transmission. In the last two decades, many researchers have been devoted to develop new techniques for image compression. More recently, wavelets have become a cutting edge technology...

Wavelet-Texture Method: BRDF Compression by using Daubechies Wavelet, Reflection Model, and Circular Polarizer

In order to create a photorealistic VR model, we have to record the appearance of the object from different directions under different illuminations. In this paper, we propose a method which renders photorealistic images from small size of data. First, we separates the images of the object into diffuse reflection component and specular reflection component by using circular polarizers. Then, we...

Wavelet-Texture Method: Appearance Compression by Daubechies Wavelet, Reflection Model, and Polarization

In order to create a photorealistic Virtual Reality model, we have to record the appearance of the object from different directions under different illuminations. In this paper, we propose a method that renders photorealistic images from a small amount of data. First, we separate the images of the object into a diffuse reflection component and a specular reflection component by using linear pol...
