An improved algorithm for eye corner detection [PDF]

open access: yes2016 International Conference on Signal Processing and Communications (SPCOM), 2016
In this paper, a modified algorithm for the detection of nasal and temporal eye corners is presented. The algorithm is a modification of the Santos and Proenka Method. In the first step, we detect the face and the eyes using classifiers based on Haar-like features. We then segment out the sclera, from the detected eye region. From the segmented sclera,

Corner detection using Gabor filters

open access: yes, 2014
This study proposes a contour-based corner detector using the magnitude responses of the imaginary part of the Gabor filters on contours. Unlike the traditional contour-based methods that detect corners by analysing the shape of the edge contours and ...

A randomised controlled non-inferiority trial to compare the efficacy of ‘HPV screen, triage and treat’ with ‘HPV screen and treat’ approach for cervical cancer prevention among women living with HIV

open access: yesNature Communications
We report results of a randomized controlled trial to compare ‘HPV screen and treat’ (Arm 1) and ‘HPV screen, triage and treat’ (Arm 2) in women living with HIV (WLHIV), using visual inspection with acetic acid (VIA) as the triaging test.

Subpixel corner point detecting method based on greyscale constraint used for calibrating industrial microscopic systems

open access: yesThe Journal of Engineering, 2019
To solve the problems of missed detection, repeated detection and low precision in the process of subpixel corner point detection of black-and-white checkerboard used for calibrating microscopic devices in complexed industrial environment, a new ...

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.

Phosphoinositides and inositol phosphates as molecular glues

open access: yesFEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Fast Event-based Corner Detection [PDF]

open access: yesProcedings of the British Machine Vision Conference 2017, 2017
Event cameras offer many advantages over standard frame-based cameras, such as low latency, high temporal resolution, and a high dynamic range. They respond to pixel-level brightness changes and, therefore, provide a sparse output. However, in textured scenes with rapid motion, millions of events are generated per second.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

A Fast and Reliable Corner Detector for Non-Uniform Illumination Mineshaft Images

open access: yesJournal of Intelligent Systems, 2013
We propose a fast and reliable corner detector that can detect corners under non-uniform illumination and fuzzy mineshaft images effectively. First, we presented an inner mask that used only four pixels to determine the flat and corner regions of an ...
