Human face detection has become a major field of interest in current research because there is no deterministic algorithm to find face(s) in a given image. Further the algorithms that exist are very much specific to the kind of images they would take as input and detect faces. The problem is to detect faces in the given, colored group photograph. This paper proposes a novel technique for detect...

Objectives. To assess visually color-matching and blending-effect (BE) of a universal shade bulk-fill-resin-composite placed in resin-composite-models with different shades and cavity sizes and in natural teeth (extracted and patients' teeth). Materials and Methods. Resin-composite-discs (10 mm × 1 mm) were prepared of universal shade composite and resin-composite of shades: A1, A2, A3, A3.5, a...

OBJECTIVE To study the in vitro color changes of three dental resin veneering materials when immersed in tea, coffee and tamarind extracts. MATERIALS AND METHODS The color changes of heat polymerized tooth colored acrylic resin (Stellondetrey, B, F14, DPI Dental products of India Ltd, Mumbai), auto polymerized tooth colored acrylic resin (DPI, B, QV5, DPI Dental products of India Ltd, Mumbai)...

The registration of images from multiple types of sensors (particularly infrared sensors and visible color sensors) is a step toward achieving multisensor fusion. This paper proposes a registration method using a novel error function. Registration of infrared and visible color images is performed by using the trajectories of moving objects obtained using background subtraction and simple tracki...

BACKGROUND AND PURPOSE Color has been shown to facilitate both visual search and recognition tasks. It was our purpose to examine the impact of a color-coding algorithm on the interpretation of 2D-DSA acquisitions by experienced and inexperienced observers. MATERIALS AND METHODS Twenty-six 2D-DSA acquisitions obtained as part of routine clinical care from subjects with a variety of cerebrovas...

Considerable work has been conducted regarding the perceptibility of color differences for simple images such as uniform color patches. From this work comes such tools as the MacAdam ellipses. Less is known regarding color difference perceptibilitywhen complex images are involved. However, the proliferation ofdesktop publishing equipment and the increasingly technically elegant accompanying sof...

This paper describes a method to restore degraded images captured in general participative media — fog, turbid water, sand storm, etc. To obtain generality, we, first, propose a novel interpretation of the participative media image formation by considering the color variation of the media. Second, we introduce that joining different image priors is an effective alternative for image restoration...

ABSTRACT: Traditionally, the color transformation method such as IHS transformation is usually used as a fusion technique to color higher spatial resolution panchromatic image from lower spatial resolution multi-spectral image. However, the analysis indicates that the success of this image fusion technique depends heavily on a small proportion of spatial resolution between multi-spectral and pa...
