Fast Adaptive Bilateral Filtering [PDF]
IEEE Transactions on Image Processing, 2019 In the classical bilateral filter, a fixed Gaussian range kernel is used along with a spatial kernel for edge-preserving smoothing. We consider a generalization of this filter, the so-called adaptive bilateral filter, where the center and width of the Gaussian range kernel is allowed to change from pixel to pixel.

Applied Sciences, 2019 Speckle is a kind of noise commonly found in ultrasound images (UIs). Although traditional local operation-based methods, such as bilateral filtering, perform well in de-noising normal natural images with suitable parameters, these methods may break ...

Adaptive Bilateral Texture Filter for Image Smoothing
Frontiers in Neurorobotics, 2022 The biggest challenge of texture filtering is to smooth the strong gradient textures while maintaining the weak structures, which is difficult to achieve with current methods. Based on this, we propose a scale-adaptive texture filtering algorithm in this

Bilateral spontaneous filtering blebs
American Journal of Ophthalmology Case Reports, 2020 To report a case of bilateral spontaneous filtering bleb, scleral thinning, microspherophakia, and mild craniofacial dysmorphism.An 18-year-old girl was referred to our clinic for evaluation of bilateral spontaneous filtering blebs. Her corrected distance visual acuity (CDVA) was 20/400 in the right eye (RE) and 20/100 in the left eye (LE).

Impact of Iterative Bilateral Filtering on the Noise Power Spectrum of Computed Tomography Images
Algorithms, 2022 A bilateral filter is a non-linear denoising algorithm that can reduce noise while preserving the edges. This study explores the characteristics of a bilateral filter in changing the noise and texture within computed tomography (CT) images in an ...

Directional bilateral filters for smoothing fluorescence microscopy images
AIP Advances, 2015 Images obtained through fluorescence microscopy at low numerical aperture (NA) are noisy and have poor resolution. Images of specimens such as F-actin filaments obtained using confocal or widefield fluorescence microscopes contain directional information

Retinex-Based Laplacian Pyramid Method for Image Defogging
IEEE Access, 2019 To address the problem that the retinex algorithm cannot effectively enhance color and detail simultaneously, we propose a retinex-based laplacian pyramid method for image defogging. The method is implemented via MSRCR and laplacian pyramid, and it doesn'
