Technological growth in semiconductor industry have led to unprecedented demand for faster, area efficient and low power VLSI circuits for complex image processing applications. DWT-IDWT is one of the most popular IP that is used for image transformation. In this work, a high speed, low power DWT/IDWT architecture is designed and implemented on ASIC using(More)
BACKGROUND Analysis of publication trends will guide the policy framers, administrators, and dentists to frame future policies and design programs for the development of scientific and technological policies in the field of dentistry. AIMS AND OBJECTIVES This study was undertaken to assess the trends in Indian Conservative dentists and endodontists'(More)
OBJECTIVE This study aimed at qualitatively evaluating the remineralization potential of casein phosphopeptide amorphous calcium phosphate on artificial early enamel lesions in an ex-vivo scenario by observing the treated tooth surface using a scanning electron microscope (SEM). MATERIALS AND METHODS This randomized study was conducted on 10 subjects(More)
Ear detection in facial images under varying pose, background and occlusion is a challenging issue. This paper proposes an entropy-cum-Hough-transform-based approach for enhancing the performance of an ear detection system, employing the unique combination of hybrid ear localizer (HEL) and ellipsoid ear classifier (EEC). By exploiting the entropic(More)
AIMS/OBJECTIVES This in vitro study was designed to measure and compare the temperature rise in the pulp chamber with different light curing units. MATERIALS AND METHODS The study was done in two settings-in-vitro and in-vivo simulation. In in-vitro setting, 3mm and 6mm acrylic spacers with 4mm tip diameter thermocouple was used and six groups were formed(More)
INTRODUCTION The objective of this study was to compare the shaping ability of three rotary filing systems; constant taper K3 instruments, constant taper ProFile instruments and progressive taper ProTaper rotary instruments in clear resin blocks with simulated curved root canals. MATERIALS AND METHODS Forty five resin blocks were divided into three(More)
