Skin burn.rar - The rapid and accurate assessment of burn injuries is a very challenging task in burn surgery. To illustrate the potential of millimeter-wave systems for burn diagnosis, the current paper at first shows a coaxial probe based ex-vivo measurement of the effective relative permittivity of skin depending on the degree of burn and also in-vivo measurements of the relative permittivity change caused by small skin irritation (i.e., increased or decreased blood perfusion, edema formation) in the frequency range 0.1 to 50 GHz. Based on the presented relation between skin condition, frequency, permittivity and loss, a MIMO-SAR imaging system operating at 75 GHz,2018-09-04 14:21:18,下载0次
Blood.rar - utomated and accurate classification of blood vessels into arteries and veins may help the ophthalmologist to find the retinal disorders. In this paper, we present a novel method for automated detection of hypertensive retinopathy. The proposed system classifies the vessel into arteries and veins using different machine learning techniques and then detects hypertensive retinopathy by computing arteriolar to Venular ratio. The proposed system is tested on one publicly available database and one locally gathered database. The quantitative results show the validity of proposed system,2018-09-04 14:04:10,下载0次
Diabetic Retinopathy.rar - Diabetes occurs when the pancreas fails to secrete enough insulin, slowly affecting the retina of the human eye. As it progresses, the vision of a patient starts deteriorating, leading to diabetic retinopathy. In this regard, retinal images acquired through fundal camera aid in analyzing the consequences, nature, and status of the effect of diabetes on the eye. The objectives of this study are to (i) detect blood vessel, (ii) identify hemorrhages and (iii) classify different stages of diabetic retinopathy into normal, moderate and non-proliferative diabetic retinopathy (NPDR). The basis of the classification of different stages of diabetic retinopathy is the detection and quantification of blood vessels and hemorrhages present in the retinal image.,2018-09-04 13:57:12,下载11次
