Wavelets on the Interval and Fast Wavelet Transforms
The paper contains a detailed analysis of several constructions of orthonormal bases of wavelets on a finite interval. A new construction is suggested which avoids some of the disadvantages of earlier constructions.

Optimal decomposition level of discrete, stationary and dual tree complex wavelet transform for pixel based fusion of multi-focused images [PDF]
The fast development of digital image processing leads to the growth of feature extraction of images which leads to the development of Image fusion. The process of combining two different images into a new single image by retaining salient features from ...

Norm Retrievable Wavelet Systems [PDF]
This paper focuses on the norm retrieval problem for wavelet transform. The wavelet transform associated with an admissible wavelet is norm retrieval. However, this problem is difficult in special cases, i.e., for wavelet systems. We give some results of

Multiscale texture classification and retrieval based on magnitude and phase features of complex wavelet subbands [PDF]
This paper proposes a multiscale texture classifier which uses features extracted from both magnitude and phase responses of subbands at different resolutions of the dual-tree complex wavelet transform decomposition of a texture image.

True 2-D 5/3 wavelet transform and its application for CT image lossless compression
Wavelet transform is widely used in the field of digital image processing,and it usually processes image by separating the row and column,which can’t meet the human visual system(HVS)completely.To address this situation,a kind of true 2-D 5/3 wavelet ...
