The measurement of aerosol acidity is important to have a comprehensive understanding chemistry, the adverse health effects particulate matter, and climate. Colorimetry Integrated with CAMera (CICAM) method demonstrated detect color change filter (impregnated an acid indicator), after application acidic aerosol, using digital images. CICAM images were analyzed by computer program that employs M...

The proposed encryption algorithm is composed of two parts, permutation and diffusion. we firstly separate the RGB image into R, G, B components, and Generate three chaotic sequences by chaotic maps to encryption. Then, transform the R, G, B components and the chaotic sequences into DNA code, and get DNA sequences matrix. Secondly, DNA matrices of the RGB image is permutated under the Chen’s hy...

BACKGROUND Computer image analysis techniques have decreased effects of observer biases, and increased the sensitivity and the throughput of immunohistochemistry (IHC) as a tissue-based procedure for the evaluation of diseases. METHODS We adapted a Cyan/Magenta/Yellow/Key (CMYK) model for automated computer image analysis to quantify IHC stains in hematoxylin counterstained histological secti...

In this paper, we describe a color segmentation based on the normalized RGB chromaticity diagram to extract the symbols and characters of road guidance signs. The proposed method separates blue color of the signs by utilizing the developed histogram on the normalized RGB chromaticity diagram for selecting the threshold automatically. The image morphology operator and the histogram projection te...

There exist two options for digital cameras that can capture the near-infrared (NIR) band. Conventional red–green–blue (RGB, visible bands) with a single sensor provide NIR band visibility based on removal of internal NIR-blocking filter. Alternatively, multisensor have specific each The modified RGB are lower price. In this context, objective study was to compare performance camera obtaining n...

The fertility of a soil is governed by potential Hydrogen (pH) value the soil. This research paper presents novel approach for predicting pH using RGB (Red, Green, Blue) values an image. study uti- lizes machine learning techniques to develop model that can accurately pre- dict based on colour information captured in image was trained with dataset containing and correspond- ing as attributes te...

In this thesis, an efficient approach for landscape image classification and matching system based on the MPEG-7 (Moving Picture Expert group) color and shape descriptor. Image classification is the task of deciding whether an image landscape or not. These classifications use the dominant color descriptor method for finding the dominant color in the image. In DCD we examine whole image pixel va...

DETECHIP® is a detection system made of various sensors that has been shown to detect and discriminate between small molecules of interest, including various illicit and over-the-counter drugs. Previously, detection was normalized to a single concentration of analyte. Now this detection assay can detect concentration differences in analytes via red, green, and blue color value changes and shift...
