A New Ultrasound Speckle Reduction Algorithm Based on Superpixel Segmentation and Detail Compensation

open access: yesApplied 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 ...

Near-Infrared Image Colorization Using Asymmetric Codec and Pixel-Level Fusion

open access: yesApplied Sciences, 2022
This paper mainly studies the colorization of near-infrared (NIR) images. Image colorization methods cannot be extended to NIR image colorization since the wavelength band of the NIR image exceeds the visible light spectral range and it is often linearly

Retinex-Based Laplacian Pyramid Method for Image Defogging

open access: yesIEEE 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'

Fast Adaptive Bilateral Filtering [PDF]

open access: yesIEEE 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.

Bilateral spontaneous filtering blebs

open access: yesAmerican 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).

Penapisan Derau Gaussian, Speckle dan Salt&Pepper Pada Citra Warna

open access: yesIJCCS (Indonesian Journal of Computing and Cybernetics Systems), 2011
Quality of digital image can decrease becouse some noises. Noise can come from lower quality of image recorder, disturb when transmission data process and weather. Noise filtering can make image better becouse will filtering that noise from the image and
