Multiple-Image Hiding by Using Single-Shot Ptychography in Transform Domain
IEEE Photonics Journal, 2017 A practical method using single-shot ptychographic imaging (SPI) in the transform domain is proposed for multiple-image hiding. The excellent compressibility of SPI can bring high multiplexing capacity and imperceptibility to the proposed multiple-image ...

Radon Transform Based on Waveform for AVO-Preserving Data Construction
Applied Sciences, 2021 The traditional hyperbolic Radon transform suffers from the major problem of how to both obtain a high resolution and preserve the amplitude variation with offset (AVO). In the Radon domain, high resolution (sparseness) is a valid criterion.

Transform domain texture synthesis [PDF]
Signal Processing: Image Communication, 2008 In this paper, we propose a fast DWT-based multi-resolution texture synthesis algorithm in which coefficient blocks of the spatio-frequency components of the input texture are efficiently stitched together to form the corresponding components of the synthesised output texture.

Application of wavelet transform for PDZ domain classification. [PDF]
PLoS ONE, 2015 PDZ domains have been identified as part of an array of signaling proteins that are often unrelated, except for the well-conserved structural PDZ domain they contain.

Sparse-View CT Reconstruction Based on a Hybrid Domain Model with Multi-Level Wavelet Transform
Sensors, 2022 The reconstruction of sparsely sampled projection data will generate obvious streaking artifacts, resulting in image quality degradation and affecting medical diagnosis results. Wavelet transform can effectively decompose directional components of image,
