In this paper, we show that zoom-endoscopy images can be well classified according to the pit-pattern classification scheme by using texture-analysis methods in different wavelet domains. We base our approach on three different variants of the wavelet transform and propose that the color-channels of the RGB and LAB color model are an important source for computing image features with high discr...

Color Space Analysis for Iris Recognition by Matthew K. Monaco Master of Science in Electrical Engineering West Virginia University Arun A. Ross, Ph.D., Chair This thesis investigates issues related to the processing of multispectral and color infrared images of the iris. When utilizing the color bands of the electromagnetic spectrum, the eye color and the components of texture (luminosity and ...

Introduction: Biomedical waste is any unwanted residual matter arising from the hospital and other health care settings. Biomedical waste management means a systematic way of disposing the health care waste. Lab Technicians involve in segregation, storage, transportation and disposal. Objective: To assess the knowledge and practice of biomedical waste management and to determine the effectivene...

While an image’s relative surround luminance increases from dark to light, the perceived contrast of the image will increase. For this reason, projected transparencies are made with higher physical contrast than reflection prints, which are intended to be viewed in an illuminated environment. Previous research shows that the surround effect is important for color appearance and device-independe...

We introduce a principle of parallel optical processing to an optofluidic lab-on-a-chip. During electrophoretic separation, the ultra-low limit of detection achieved with our set-up allows us to record fluorescence from covalently end-labeled DNA molecules. Different sets of exclusively color-labeled DNA fragments-otherwise rendered indistinguishable by spatio-temporal coincidence-are traced ba...

UNLABELLED There is no consensus about the waiting time necessary for the patient to start consuming beverages containing colorants again after bleaching. OBJECTIVE To evaluate the influence of beverages with coloring agents on bleached bovine incisors considering the time elapsed after bleaching. MATERIALS AND METHODS Sixty bovine incisors were bleached with 35% hydrogen peroxide for in-of...

Automatic shot boundarydetection andkeyframe selection constitute major goals in video processing. We propose two different information-theoretic approaches to detect the abrupt shot boundaries of a video sequence. These approaches are, respectively, based on two information measures, Tsallis mutual information and Jensen–Tsallis divergence, that are used to quantify the similarity between two ...

the objective of this research was to develop a suitable method for color sorting of fruits. accordingly, a color-sorting system was designed and a prototype developed and then tested. this system includes an optic head which is designed to develop a reflection of the fruit. output of the head is then processed in an electronic control system which generates the appropriate signal for ejection ...
