Compactly Supported Tensor Product Complex Tight Framelets with Directionality
Xiaosheng Zhuang, Bin Han · 2019
Construction of directional compactly supported tensor product complex tight framelets cptTP-ℂTF6is discussed. The construction algorithm employs optimization techniques and puts extensive emphasis on frequency response and spatial localization of the underlying one-dimensional tight framelet filter banks. A concrete example of cptTP-ℂTF6is provided. Numerical experiments show that such constructed cptTP-ℂTF6have good performance in image denoising.
