Local characterization of neovascularization and identification of proliferative diabetic retinopathy in retinal fundus images
Diabetic retinopathy is a progressive disease, with various signs indicating different stages. The advanced, sight-threatening stage of DR is termed as proliferative diabetic retinopathy (PDR). The onset of PDR is characterized by neovascularization, identifiable on the retinal image as a tangle of abnormal new vessels which are thin, weak, exhibit irregular appearance, do not bifurcate like normal vessels, and appear to form frond-like tortuous patterns and florid loops. Neovascularization (NV) can rapidly progress to bleeding, fibrous proliferation, vitreous haemorrhage and retinal detachment, culminating in blindness. (...

Influence of applied corneal endothelium image segmentation techniques on the clinical parameters
The corneal endothelium state is verified on the basis of an in vivo specular microscope image from which the shape and density of cells are exploited for data description. Due to the relatively low image quality resulting from a high magnification of the living, non - stained tissue, both manual and automatic analysis of the data is a challenging task. Although, many automatic or semi-automatic solutions have already been introduced, all of them are prone to inaccuracy.This work presents a comparison of four methods (fully-automated or semi-automated) for endothelial cell segmentation, all of which represent a different a...

Accurate HEp-2 Cell Classification Based on Sparse Bag of Words Coding
Autoimmune Diseases (AD) arise from abnormal immune responses of the body against normally present substances and tissues in the body where autoantibodies produced by the immune system are directed against one or more of the individual's own proteins (Cotsapas and Hafler, 2013). Early diagnosis of ADs that affect the neuromuscular system, hepatobiliary system, vasculitic syndromes, etc. plays an important role in the AD treatment. Antinuclear Antibody (ANA), a type of autoantibody that binds to contents of the cell nucleus, is generally considered as a hallmark of ADs. (Source: Computerized Medical Imaging and Graphics)

Automatic detection of microaneurysms in retinal fundus images
Diabetic retinopathy (DR) is one of the main complications caused by diabetes. It is reported that DR has been the leading cause of new cases of blindness among adults between 20 and 60 years old (Walter et al., 2007). According to the World Health Organization (WHO), 347 million people were diagnosed with diabetes worldwidely (World Health Organization (WHO), 2016). It is also predicted that, by 2040, more than 640 million people may be living with diabetes (International Diabetes Federation, 2016). (Source: Computerized Medical Imaging and Graphics)

Ensemble based adaptive over-sampling method for imbalanced data learning in computer aided detection of microaneurysm
Diabetic Retinopathy (DR) is a chronic progressive disease of the retinal microvasculature which is the most common cause of blindness in the past 50 years. Due to the burden of diabetes over the past decades, the prevalence of DR is expected to grow exponentially and affect over 366 millions people worldwide by 2030 (Erbas et al., 2011). Despite the high risk factor, it has been established that early detection and timely treatment can reduce the development of severe vision loss in 60% of cases.

An improved wavelet threshold applied to surface electromyogram de-noising
Surface Electromyogram (sEMG), which is recorded by the electrodes from the skin surface, can reflect the weak bioelectric signals of the related activation of neuromuscular system (Luca and Carlp, 1979). It has been widely applied in the field of basic research, clinical medicine, rehabilitation medicine and sports medicine etc. (Yin, 2013). It is also well established that sEMG is a nonlinear and non-stationary signal (Xugang et al., 2012). In addition, its peak value is in the range of 0 –10mV and the useful signal energy is very weak, which is generally in the range of 10Hz–50Hz. (Source: Computerized Medical Imaging and Graphics)

Surface Reconstruction for Planning and Navigation of Liver Resections
Liver cancer is the second most common cause of cancer death worldwide (Jemal et al., 2011). Hepatocellular carcinoma (HCC), which accounts for 70% to 80% of the cases (Vanni and Bugianesi, 2014), presents a 5-year survival rate below 12% (El-serag, 2011). Colorectal cancer metastatic to the liver, on the other hand, develops in 50% of the cases of colorectal cancer, and presents 5-year survival rates up to 58% for selected patients undergoing liver resection (Misiakos et al., 2011).

Volumetric Image Classification using Homogeneous Decomposition and Dictionary Learning: A Study Using Retinal Optical Coherence Tomography for Detecting Age-related Macular Degeneration
Medical imaging is one of the most important breakthroughs in the management of various conditions. Such images are extensively used in day-to-day clinical practice to support the diagnosis, management and prognosis of medical conditions. The images of interest have tended to be two-dimensional (2D); but 3D or volumetric images, such as those produced using Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and Optical Coherence tomography (OCT) are becoming increasingly prevalent. However, there has been no corresponding increase in the availability of software tools to support the analysis of large amounts of med...

Performance Comparison of Publicly Available Retinal Blood Vessel Segmentation Methods
Visual examination of the retina provides a non-invasive view into the eye and at the same time into the central nervous system. One of the distinct features of the retina are the blood vessels, whose structure is an important indicator of disorders such as diabetes, hypertension and cardiovascular disease Kanski and Bowling (2013). Retinal imaging has been used to characterize the vessel structure, and diagnose, monitor and document abnormal conditions Liew et al. (2008). With current technology, it is already possible to produce quantitative information of the signs of eye diseases like diabetic retinopathy and glaucoma,...
