PURPOSE: A method and apparatus for photographing an image of a multiple spectrum electromagnetic wave are provided to improve monitoring efficiency by accurately analyzing the image of the multiple spectrum electromagnetic wave. CONSTITUTION: A first camera(110) photographs a visible image. A second ...
Within the electromagnetic spectrum, the most common wavelengths that are used for crop monitoring applications are green, red and NIR. Plant pigments dominate the reflectance of vegetation in the VIS wavelengths. Chlorophyll absorbs red and blue energy and reflects green. Cellular structure of leaves...
As that star "wobbles" away from Earth (and Gaia), the wavelength of light stretches, shifting it toward the red end of the electromagnetic spectrum. Conversely, when it wobbles toward Earth, the wavelengths of light are shortened, shifting the light toward the blue end of the electromagnetic ...
"By combining data from telescopes operating across the electromagnetic spectrum, scientists can gain greater insight into astronomical objects than by using a single observatory — even one as powerful as Webb," the space agency said. M74 shines at its brightest in this combined optical/m...
1. Image processing deals with different techniques of transformation existing image to the new image, which has a better quality for man perception or for the subsequent machine processing. 数字图像处理涉及将现有图像转换为新图像的不同技术,新图像对于人类感知或后续机器处理具有更好的质量。 The serious...
In subject area: Computer Science A hyperspectral image is an image in which the spectrum of light is measured for each pixel. It is obtained through various electromagnetic measurements and allows for high spectral resolution, with more bands acquired in a smaller wavelength range. ...

The main objective of this work is to extract the hand vein network using a non-invasive technique in the near-infrared region (NIR). The visualization of the veins is based on a relevant feature of the blood in relation with certain wavelengths of the electromagnetic spectrum. In the ...
Channels 4, 3, and 2 cover the near infrared (NIR), the visible red, and the visible green parts of the electromagnetic spectrum. When they are mapped to the red, green, and blue planes, respectively, of an RGB image, the result is a standard color-infrared (CIR) composite. The final...
An apparatus for the electromagnetic spectrum or optical analysis of a material. The apparatus comprising a measuring probe having a housing with at least one radiation or light measuring element, a measuring window and with at least one detection element for the analysis. The measuring probe is ...
