The invention is inspired by the desire to understand the opportunities and expectations of developing economies in terms of healthcare. The designed system is a point-of-care (POC) device that can deliver heart-care services to the rural population and bridge the rural-urban divide in healthcare delivery. The product design incorporates several innovations(More)
Microscope optics presents two critical limitations of low depth of field and very low or no depth perception. Due to low depth of field, at high magnification levels microscope cannot adequately focus on the object. This can adversely affect the performance of slide digitization procedure in digital pathology. This paper presents a depth of field extension(More)
Majority of images in digital pathology require post acquisition adjustments to optimize brightness, contrast, and image visibility. Despite this fact much research effort has not been put in development of customized contrast enhancement techniques for this application. In this respect various contrast enhancement techniques developed for other application(More)
Quantitative evaluation of histopathological features is not only vital for precise characterization of any precancerous condition but also crucial in developing automated computer aided diagnostic system. In this study segmentation and classification of sub-epithelial connective tissue (SECT) cells except endothelial cells in oral mucosa of normal and OSF(More)
This paper presents the acquisition of heart sound signals and its separation from lung sounds based on the adaptive filtering technique. After signal acquisition, normal linear filtering techniques is not capable separated the two sounds, as both the sounds overlap in the spatial as well as temporal domains. Because of the signal tracking and noise(More)
Computer vision systems are being introduced in pre-screening of cervical cytopathology slides to identify samples that require study by cytopathologists. These systems work on the principle of imaging and analysis of cytology features in general and nuclear features in particular. Thus accurate localization and segmentation of the nuclei is crucial for the(More)
This paper presents a fast and accurate auto white balance scheme specifically suited for white balance (WB) correction in digital pathology applications. The scheme uses low-level statistics based technique for illuminant estimation and linear transformation method for image correction. The WB performance of the proposed scheme has been tested in various(More)
