Increased Endurance of Nonvolatile Photonics Enabled by Nanostructured Phase‐Change Materials
Advanced Materials, EarlyView.Tapered and segmented islands of the phase‐change material (PCM) antimony selenide (Sb2Se3) integrated on silicon microring resonators enable ultra‐low‐loss, high‐endurance, non‐volatile photonic tuning. The nanostructured PCM design suppresses interfacial scattering and thermal stress, achieving record endurance over 100 million electrical switching ...

FETAL ULTRASOUND IMAGE DENOISING USING CURVELET TRANSFORM [PDF]
ICTACT Journal on Image and Video Processing, 2015 The random speckle noise in the acquired fetal ultrasound images is caused by the interference of reflected ultrasound wave fronts. The presence of speckle noise will degrade the quality of the image and even hide image details, which in turn affect the ...

A novel fuzzy filter for speckle noise removal
TURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2014 In this paper, a novel fuzzy system-based method for speckle noise removal is proposed. The proposed method consists of a fuzzy inference system, an edge detection and dilation unit, and an image combiner. The fuzzy inference system includes 5 inputs and 1 output, and it is responsible for ltering the speckle noisy image. The inputs of the fuzzy system
