Iris Segmentation Using a Statistical Approach [PDF]

, 2010
Eyelashes and reflections occluding the iris region are noise factors that degrade the performance of iris recognition. If these factors are not eliminated in iris segmentation phase, they are incorrectly considered as the iris region. Thus, produce false iris pattern information which decreases the recognition rate.

Safety and Perioperative Outcomes of Immediate Versus Delayed Sequential Bilateral Cataract Surgery in the Pediatric Population: A Systematic Review and Meta‐Analysis

Eye &ENT Research, EarlyView.
ABSTRACT Background Bilateral congenital cataracts are a major cause of preventable childhood blindness. Although delayed sequential bilateral cataract surgery (DSBCS) has traditionally been the preferred approach, immediate sequential bilateral cataract surgery (ISBCS) is increasingly being considered to reduce anesthesia exposure and healthcare ...

Review of Deep Learning Based Iris Recognition [PDF]

Jisuanji kexue yu tansuo
The highly accurate, secure, and stable biometric technology of iris recognition is well-known. The current iris recognition system shows stable performance under the condition of constraints on user status and acquisition equipment, but it cannot adapt ...

Proteomic signatures of equine dental tooth tissues in ageing and disease

Equine Veterinary Journal, EarlyView.
Abstract Background Ageing and dental disease in horses lead to structural and functional deterioration of dental tissues, yet their molecular signatures remain poorly characterised. Understanding how these processes alter the protein composition of enamel, dentin, cementum and pulp is essential for improving equine oral health and identifying ...

Tropical Cyclone Rainfall Spatial Asymmetries in the Lesser Antilles

International Journal of Climatology, EarlyView.
Rainfall is not proportional to the Saffir‐Simpson wind‐based categories. Lower category tropical cyclones (TS, H1, H2 and H3) can generate more intense rainfall than H4 and H5. Rainfall is asymmetric; as a tropical cyclone intensifies or weakens, the location of peak rainfall shifts.

Biomass Carbon in Harvest Residues of Winter Oilseed Rape Across Fertilizer N Rates: Implications for Carbon Input Estimations in Soil Carbon Models

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: Reliable estimation of carbon (C) inputs from above‐ and belowground residues at different yield levels is crucial, as these inputs drive soil organic carbon (SOC) models for C accounting. Aims: This study quantifies C inputs from different components of winter oilseed rape (WOSR) and compares them with estimates from various ...

Incremental and Enhanced Scanline-Based Segmentation Method for Surface Reconstruction of Sparse LiDAR Data

Remote Sensing, 2016
The segmentation of point clouds is an important aspect of automated processing tasks such as semantic extraction. However, the sparsity and non-uniformity of the point clouds gathered by the popular 3D mobile LiDAR devices pose many challenges for ...

A Novel Slit Lamp‐Based System for 3D Ultrasound of the Eye

Journal of Ultrasound in Medicine, EarlyView.
Objectives This study aims to develop and evaluate a novel slit‐lamp‐based system to acquire 3‐dimensional (3D) ultrasound volumes using conventional ultrasound probes. Methods A slit‐lamp adapter was 3D printed and connected with a linear actuator and graphical user interface (GUI) system to control movement and create volumes of 2‐dimensional scans ...
