A robust and automatic system has been developed to detect the visual axis and extract important feature landmarks from slit-lamp photographs, and objectively grade the severity of nuclear sclerosis based on the intensities of those landmarks. Using linear regression, we first select the features that play important roles in classification, and then fit a linear grading function. We evaluated t...
Grading of agricultural produce especially the fruits and vegetables has become a perquisite of trading across borders. In India mostly fruit and vegetable growers grade the fruit manually. Manual grading was carried out by trained operators who considered a number of grading factors and fruit were separated according to their physical quality . Manually grading was costly and grading operation...
Background: Definite data regarding the incidence and distribution of renal tumours in eastern India is not known. For better management, as it is essential to identify patients with poor prognosis, prognostic factors like stage, nuclear grade and their relationship to molecular markers are also unclear in this region. The purpose of our study was to assess the spectrum of adu...
Automatic Essay Assessor (AEA) is a system that utilizes information retrieval techniques such as Latent Semantic Analysis (LSA), Probabilistic Latent Semantic Analysis (PLSA), and Latent Dirichlet Allocation (LDA) for automatic essay grading. The system uses learning materials and relatively few teacher-graded essays for calibrating the scoring mechanism before grading. We performed a series o...
In 2005, the International Society of Urological Pathology (ISUP) introduced several modifications to the original Gleason system that were intended to enhance the prognostic power of Gleason score (GS). The objective of this study was to clinically validate the 2005 ISUP Gleason grading system for its ability to detect metastasis. We queried our institutional RP database for men with NCCN clin...
Correlation of Visick grading was done with serial endoscopies in 19 patients operated for duodenal ulceration. Deeper mucosal lesions like ulceration showed good association with Visick grading (100%), while superficial mucosal lesions were mostly asymptomatic and therefore, caused disparity in grading. Moreover, as symptoms and endoscopic findings changed with passage of time, it was conclude...
BACKGROUND AND PURPOSE Novel angiographic grading scales for the assessment of intracranial aneurysms treated with flow-diverting stents have been recently developed because previous angiographic grading scales cannot be applied to these aneurysms. The purpose of this study was to evaluate the inter- and intraobserver variability of the novel O'Kelly Marotta grading scale, which was developed s...
Systematic screening for diabetic retinopathy using retinal photography has been shown to reduce the incidence of blindness among people with diabetes. The implementation of diabetic retinopathy screening programmes faces several challenges. Consequently, methods for improving the efficiency of screening are being sought, one of which is the automation of image grading involving detection of im...
