Adaptive and Feature-Preserving Mesh Denoising Schemes Based on Developmental Guidance
IEEE Access, 2020 Distinguishing among different kinds of features as well as noises on 3D mesh models is crucial for feature-preserving mesh denoising. This paper proposes to address this issue via in-depth analysis of the intermediate products of the denoising processes,

Mutually Guided Image Filtering
IEEE Transactions on Pattern Analysis and Machine Intelligence, 2020 Filtering images is required by numerous multimedia, computer vision and graphics tasks. Despite diverse goals of different tasks, making effective rules is key to the filtering performance. Linear translation-invariant filters with manually designed kernels have been widely used. However, their performance suffers from content-blindness.

The use of a fiber comb filter fabricated by a CO2 laser irradiation to improve the resolution of a ratiometric wavelength measurement system [PDF]
, 2012 An edge filter based ratiometric wavelength measurement system is modelled and analysed in this paper. The results confirm that the noise of input signal and photodetectors limit the resolution of the wavelength measurement system.

Weighted median guided filtering method for single image rain removal
EURASIP Journal on Image and Video Processing, 2018 Because there is no temporal information available, rain removal with a single image is more challenging than that with a video. In this paper, we present a weighted median guided filtering method for rain removal with a single image.

Spectral-Spatial Joint Classification of Hyperspectral Image Based on Broad Learning System
Remote Sensing, 2021 At present many researchers pay attention to a combination of spectral features and spatial features to enhance hyperspectral image (HSI) classification accuracy. However, the spatial features in some methods are utilized insufficiently.

Fusion of Multi-Baseline and Multi-Orbit InSAR DEMs with Terrain Feature-Guided Filter
Remote Sensing, 2018 Interferometric synthetic aperture radar (InSAR) is an effective technology for generating high-precision digital elevation models (DEMs). However, the vertical accuracy of InSAR DEMs is limited by the contradiction between height measurement sensitivity
