There is an increasing demand for automated detection and analysis of dermoscopy structures and malignancy clues such as streaks in dermoscopy images, for computer-aided early diagnosis of deadly melanoma. This paper presents a novel approach for streak detection and visualization on dermoscopic images. We tackle the detection of streaks by means of ridge and valley estimation. Orientation esti...

Given a single input rainy image, our goal is to visually remove rain streaks and the veiling effect caused by scattering and transmission of rain streaks and rain droplets. We are particularly concerned with heavy rain, where rain streaks of various sizes and directions can overlap each other and the veiling effect reduces contrast severely. To achieve our goal, we introduce a scale-aware mult...

OBJECTIVE To analyze dermoscopically identified streaks by direct correlation with features visualized on reflectance confocal microscopy (RCM). DESIGN We evaluated by RCM melanocytic lesions showing peripheral streaks on dermoscopy. A digital camera connected to the RCM computer enabled direct analysis of the streaks. The lesions were excised and histopathologically analyzed. SETTING Derma...

This paper proposes a scale space total variation (ssTV) algorithm to reduce large scale streaks in limited angle tomography. The weighted total variation (wTV) algorithm is able to remove most small scale streaks. However, it fails to reduce larger streaks since total variation (TV) regularization is scale-dependent and may regard them as homogeneous areas. Derived from the wTV algorithm, the ...

Introduction: Slope streaks on Mars, first observed in Viking Orbiter images [1], were imaged in detail by MGS MOC [2,3], and have been observed to form and change over less than decadal time periods [3]. Typically displaying a low albedo relative to their surroundings, they show no detectable relief, are elongated downslope, usually <200 m in width, and usually extend for distances ranging fro...

SAR image acquired in the nighttime (10:30 PM local time) at the magnetic equatorial regions, i.e., Amazon, Africa, and the south East Asian areas, are often interfered by the streaks since the ALOS launch of the Jan. 24, 2006. These streaks appear both in amplitude image and phase of the SAR data, which contain the interferometric fringe and polarimetric phase. JAXA/EORC is conducting the quic...
