The theory behind compression systems is well established, and it is a common assumption that image compression systems such as DCT (Discrete Cosine Transform) perform better in a decorrelated space than with the highly correlated RGB (Red, Green, Blue) components. YUV is therefore the main choice for compression systems instead of the original RGB domain. As a result, several questions arise: ...

A novel technique suitable for noninvasive measurements of moss water content is presented. In this paper, colour image sensing is applied for measuring moss water content. Sunagoke moss Rhacomitrium canescens has been utilized as an active greening material to mitigate the urban heat island effect. The goal of this paper is to develop an intelligent image analysis system for water irrigation o...

In this paper, HSV based color motif co-occurance matrix (HSV-Motif) is proposed for content based image retrieval (CBIR). The HSV-Motif is proposed in contrast to the RGB based color motif co-occurance matrix (RGB-Motif). First the RGB (red, green, and blue) image is converted into HSV (hue, saturation, and value) image, then the H and S images are used for histogram calculation by quantizing ...

We propose a design for an electrochemically driven RGB dye based on a tristable [2]catenane, in which the color of the molecule can be switched between Red, Green, and Blue by merely changing voltage. Based on DFT calculations, we conclude that the tristable [2]catenane should consist of a CBPQT4+ ring interlocked with a polyether macrocyle containing DNP (red), TTF (green), and FBZD (blue) un...

Recent project of National Aeronautics and Space Administration (NASA) to Mars promised to show 3D images of Mars surface. Spirit and Opportunity, identical Mars rovers of NASA, are equipped with a high-resolution stereo camera pair, called PanCam. Most cameras used by people are sensitive to three color bands, namely red (R), green (G) and blue (B). The PanCam is equipped with more color bands...

agricultural sector experiences the application of automated systems since two decades ago. these systems are applied to harvest fruits in agriculture. computer vision is one of the technologies that are most widely used in food industries and agriculture. in this paper, an automated system based on computer vision for harvesting greenhouse tomatoes is presented. a ccd camera takes images from ...

BACKGROUND There is a subjective disagreement about nuclear chromatin in the field of pathology. Objective values of red, green, and blue (RGB) light intensities for nuclear chromatin can be obtained through a quantitative analysis using digital images. METHODS We examined 10 cases of well differentiated neuroendocrine tumors of the rectum, small cell lung carcinomas, and moderately different...

An inverse approach is applied for image improving during visualization of electromagnetic fields. The red, green, blue color (RGB) model is used. The RGB color sources have been evaluated using the RGB color distributions of the electromagnetic field data set. The Generalized Sampled Pattern Matching method is applied to solve an ill posed linear system of equations for the corresponding inver...

For hiding secret information in images, there exist a large variety of steganographic techniques, some are more complex than others and all of them have respective strong and weak points. In the proposed method, all pixels of the cover image can be used but message bit is stored in LSB of one of the three color components, Red(R), Green(G), Blue(B) based on the parity of three LSBs of R, G, B ...

Plants will be an important component of future long-term space missions. Lighting systems for growing plants will need to be lightweight, reliable, and durable, and light-emitting diodes (LEDs) have these characteristics. Previous studies demonstrated that the combination of red and blue light was an effective light source for several crops. Yet the appearance of plants under red and blue ligh...
