Ridgelet-type Frame Decompositions for Sobolev Spaces related to Linear Transport [PDF]

, 2018
In this paper we study stability properties of ridgelet and curvelet frames for mixed-smoothness Sobolev spaces with norm $\|f\|_{s} = \|f\|_{L_{2}(\mathbb{R}^{d})} +\|s\cdot\nabla f\|_{L_{2}(\mathbb{R}^{d})}$ .

Sliced Ridgelet Transform for Image Denoising

IOSR Journal of Computer Engineering, 2013
Image denoising based on ridgelet transforms gives better result in image denoising than standard wavelet transforms. In this research work, the researcher introduces a new approach for image denoising that is based on ridgelets computed in a localized manner and that is computationally less intensive than curvelets, but similar donising performance ...

Multi-scale analysis of the roughness effect on lubricated rough contact [PDF]

, 2014
Determining friction is as equally essential as determining the film thickness in the lubricated contact, and is an important research subject. Indeed, reduction of friction in the automotive industry is important for both the minimization of fuel ...

Content-based image retrieval using colour and shape fused features [PDF]

, 2013
Multi-feature methods are able to contribute to a more effective method compared to single-feature methods since feature fusion methods will be able to close the gap that exists in the single-feature methods.
