Magnetic Resonance Imaging (MRI) in diagnosing brain cancers is widespread. Because of the variety angles and clarity anatomy, it commonly employed. If a tumor malignant or secondary, high risk, leading to death. These tumors have an increased predisposition for spreading from one place another. In detecting abnormality form such as tumor, magnetic resonance scan, expertise human involvement ar...

This paper presents the results of using the shape, size and color features of an image for content-based image retrieval. The use of granulometries has been applied to model the size and shape of the connected components of the image. Granulometry are computed by successively sieving an image using filters of increasing size parameter so that information can be obtained about the components th...

development of a suitable method for color sorting of agricultural products such as: tomato, apple and orange, based on surface reflection and image formation was the goal of this research. a suitable scheme of color differentiation using an optic head and electrical processing circuitry for separating red from green and other colors is presented. a photo-conductive transducer, electrical resis...

The production of land use and cover (LULC) maps using UAV images obtained by RGB cameras offering very high spatial resolution has recently increased. Vegetation indices (VIs) have been widely used as an important ancillary data to increase the limited spectral information image in pixel-based classification. main goal this study is analyze effect frequently RGB-based VIs including green leaf ...

Conventionally, acoustic imaging has been performed using a single frequency or a limited number of frequencies. However, the rich information on surface profiles, structures hidden under surfaces and material properties of objects may exhibit frequency dependence. In this study, acoustic imaging on object surface was conducted over a wide frequency range with a fine frequency step, and a metho...

Abstract This study aims for producing high-quality true-color red-green-blue (RGB) imagery that is useful interpreting various environmental phenomena, particularly GK2A. Here we deal with an issue general atmospheric correction methods RGB might be breakdown at high solar/viewing zenith angle of GK2A due to erroneous path lengths. Additionally, there another about the green band which centroi...

In many court cases, surveillance videos are used as significant court evidence. As these surveillance videos can easily be forged, it may cause serious social issues, such as convicting an innocent person. Nevertheless, there is little research being done on forgery of surveillance videos. This paper proposes a forensic technique to detect forgeries of surveillance video based on sensor patter...

In this paper, we propose a type of joint feature with geometric parameters and color moments to represent the speaking-mouth frames for image-based visual speech synthesis systems. Based on FDP around the mouth area, the geometric feature is obtained by computing Euclidean distances to describe the width of the speaking mouth, the height of the outer and inner lips and the distances between th...

Recently, significant interest has been attracted by the potential use of aluminum nanostructures as plasmonic color filters to be great alternatives to the commercial color filters based on dye films or pigments. These color filters offer potential applications in LCDs, LEDs, color printing, CMOS image sensors, and multispectral imaging. However, engineering the optical characteristics of thes...

This paper presents an IF1F2 color space for describing colors in microscopic images. Unlike the classical color spaces that treat the R, G, and B (RGB) components of a pixel’s color as independent elements, the proposed color space treats RGB as a sampled spectral signal, called a RGB signal. Then, based on the Fourier spectrum analysis of the RGB signal, the 1-D discrete Fourier transform is ...
