, the area of the wrong view of the phenomenon will be more obvious. Hue ring under CMYK color model Color expansion, contraction is not only related to the wavelength (hue), but also related to lightness. Any optical imaging system, including the eyes, will inevitably produce spherical aberration (for short), bright objects in the retina of the image of the contour appears to have a circle of aperture around, so that the object in the retina of t

Abstract:The development of the signal processing circuit of the infrared focal plane array is introduced. The basic structure, working mode and application fields of CCD Multi-Channel transmitter (CCD-MUX), time delay integrated CCD (TDI-CCD), MOS and CMOS multi-channel transmitter (CMOS-MUX) are described. Finally, two application circuits of multichannel transmission devices are provided. Keywords:Signal processing circuit of infrared focal plane array for multi-channel transmitter infrared d

I have some questions about Panasonic and Sony ......I 'd like to ask another question. The sensor is very important. Are there any ideas about the lens?GF3's most attractive cookies are really portable ~~ Answer Sensors are the most important factor in determining image quality,In contrast, the effect of the lens quality is slightly

According to the imaging band Classification of the sensor, the optical image usually refers to the image data obtained by visible light and some infrared band sensors. And the SAR sensor basically belongs to the microwave frequency band, the wavelength is usually in centimeter level.Visible images typically contain grayscale information from multiple bands to facilitate the identification of targets and classification extractions. The SAR image only

A reminder is: can not only by virtue of the high-fetal protein (4) of the indicators to diagnose or exclude a disease is unreliable, because the discovery of liver cancer does not necessarily need a high-fetoprotein, some liver cancer may be a normal fetal protein value, it should be combined with other serological examination and imaging examination of comprehensive

Search on the Internet, there are a lot of, the following is the image processing, good cast and the quality of the article has a great relationship, if it is the first time to vote, and not urgent to the article, I suggest that the quality of the article rather than the journal slightly better, so that can learn more Slightly more than PAMI,IJCV periodicals have tip,iet Image processing, computer vision and image understanding, image and vision computing, and so on, slightly worse than PR There

[OpenCV] ry distortion correction and local enhancement, opencv ry distortion correction1. Principle During image acquisition, due to the non-linearity of the imaging system and the changes in the attitude of the aircraft, the image after imaging may be out of proportion or even distorted compared with the original image. This type of image degradation is known as geometric distortion (distortion ).This is

core library because the table processing subroutine is part of the window System. Some window systems support multiple color tables, while others have only one color table and a limited selection. However, there is a glut subroutine that can be used to interact with the windowing system to specify the color for a given index position:Glutsetcolor (index, red, green, blue);color Parameters red, green and blue are given floating-point numbers in the range from 0.0 to 1.0. The color is loaded int

X-ray tomography (tomography)There are two different imaging methods in business: CT, MRI, and the two methods have some similarities in the method of realization, which is about Ct.A body profile is assumed to contain a variety of sticky substances, such as bones, muscles, blood vessels, and spinal cords, described by variable density function $\mu (x_1,x_2) $. If we know what $\mu$ is, it means that we can know the condition of the body profile.Abou

digital signal. The reason for this difference is that the special technology of the CCD ensures that the data will not be distorted during transmission, so that the data of each pixel can be aggregated to the edge and then amplified, and the data of the CMOS process will produce noise when the transmission distance is longer, so the data of each pixel must be enlarged before being integrated.Technical Comparison of 2 CCD and CMOS sensorCCD storage charge information, need to be under the contr
