Multiscale texture classification and retrieval based on magnitude and phase features of complex wavelet subbands [PDF]
, 2011 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.

Spectral Segmentation with Multiscale Graph Decomposition
2005 IEEE Computer Society Conference on Computer Vision and Pattern Recognition (CVPR'05), 2005 We present a multiscale spectral image segmentation algorithm. In contrast to most multiscale image processing, this algorithm works on multiple scales of the image in parallel, without iteration, to capture both coarse and fine level details. The algorithm is computationally efficient, allowing to segment large images.

Shape classification via image-based multiscale description [PDF]
, 2011 We introduce a new multiscale Fourier-based object description in 2-D space using a low-pass Gaussian filter (LPGF) and a high-pass Gaussian filter (HPGF), separately.

Remote Sensing Image Fusion Based on Adaptively Weighted Joint Detail Injection
IEEE Access, 2018 Remote sensing image fusion based on the detail injection scheme consists of two steps: spatial details extraction and injection. The quality of the extracted spatial details plays an important role in the success of a detail injection scheme.

Multiscale finite elements for linear elasticity: Oscillatory boundary conditions
, 2022 S.237-245We extend the multiscale finite element method with oscillatory boundary conditions, introduced for scalar elliptic PDEs by Hou and Wu (J. Comput. Phys. 134:169-189, 1997), to the system of anisotropic linear elasticity.
