Complexity, Volume 2021, Issue 1, 2021., 2021 During the phase of periodic asphalt pavement survey, patched and unpatched potholes need to be accurately detected. This study proposes and verifies a computer vision‐based approach for automatically distinguishing patched and unpatched potholes. Using two‐dimensional images, patched and unpatched potholes may have similar shapes.

Localization Operators for Ridgelet Transforms [PDF]
Mathematical Modelling of Natural Phenomena, 2014 We prove that localization operators associated to ridgelet transforms with L p symbols are bounded linear operators on L 2 (Rn ). Operators closely related to these localization operators are shown to be in the trace class and a trace formula for them is given.

A Novel Optimized Semi-Blind Scheme for Color Image Watermarking
IEEE Access, 2020 Image watermarking is a robust solution for solving key issues like copyright protection and proof of ownership of digital data. Existing schemes of image watermarking mostly used grayscale or binary images as embedded watermarks, while only a few ...

Face recognition based on ridgelet transforms
Procedia Computer Science, 2010 AbstractThis paper relates to a face recognition and verification technique based on ridgelet transforms. Our proposed method first uses the ridgelet transform of the face image for feature extraction. This involves first applying a sequen- tial combination of radon and wavelet transforms to both the training and test images.

Analysis of the Spatial Distribution of Galaxies by Multiscale Methods
EURASIP Journal on Advances in Signal Processing, 2005 Galaxies are arranged in interconnected walls and filaments forming a cosmic web encompassing huge, nearly empty, regions between the structures. Many statistical methods have been proposed in the past in order to describe the galaxy distribution and ...

Cybernetics and Information Technologies, 2020 Due to sparsity and multiresolution properties, Mutiscale transforms are gaining popularity in the field of medical image denoising. This paper empirically evaluates different Mutiscale transform approaches such as Wavelet, Bandelet, Ridgelet, Contourlet,
