Computer-Assisted System for Hypertensive Risk Determination through Fundus Image Processing

, 2013
From a fundus image, the system proposed in this paper automatically detects retinal vessels and measures some geometrical properties on them such as diameter and bifurcation angles. Its goal is to establish objective relations between different vessels, thus being able to determine cardiovascular risk or other diseases, as well as to monitor their ...

<title>Computer-assisted image processing for lung cancer localization</title>

SPIE Proceedings, 1996
Autofluorescence of the tumor and surrounding tissue is the largest background source in fluorescence diagnosis. A new system which applied computer image processing technique to lung cancer localization by laser fluorescence bronchoscopy has been developed to subtract the autofluorescence background.

Pre-processing, Extraction and Recognition of Binary Erythrocyte Shapes for Computer-Assisted Diagnosis Based on MGG Images

, 2010
The paper presents an approach for computer-assisted diagnosis of some diseases (e.g. anaemia, malaria), which are caused by deformations of erythrocyte shapes. In the method firstly the thresholding of the input MGG image is performed, using modified thresholding based on fuzzy measures. Secondly, every cell is localised and extracted.

Computer-assisted image processing 12 lead ECG model to diagnose hyperkalemia

Journal of Electrocardiology, 2017
We sought to develop an improved 12 lead ECG model to diagnose hyperkalemia by use of traditional and novel parameters.We retrospectively analyzed ECGs in consecutive hyperkalemic patients (serum potassium (K)>5.3mEq/L) by blinded investigators with normokalemic ECGs as internal controls.
