format for the film industry . Raw Raw image File The memory data obtained directly from the digital camera, including images obtained from the graphics sensor without white-point processing and gamma correction. Different cameras use different suffixes, such as TIFF,.NEF,. RAF and. CRW . DGN Digital Negative Subcl

Ji LaserBarcode scanningAfter the technology, let's take a look at the digital imaging technology. Digital Imaging Technology is divided into Area-type digital imaging devices and linear imaging devices. What is the difference between an area-based digital photo generator and a linear photo generator? What are their re

The optimization of photos taken by the camera, limited by a number of factors, does not necessarily directly get the perfect picture, even professional photographers. And the traditional camera film, in the printing as a photo, the effect is not ideal to be corrected during this period. If you want to scan the film into electronic images, to facilitate the exchange of editors and the Internet, scan the fil

CMOS The aspect ratio) is different, so either cut a part or leave the white side. This explanation seems quite reasonable, but in the past two years, I have printed at least one or two thousand digital photos in other digital printing shops, and they were taken with different digital cameras, but never encountered such a problem. I have seen white edges around

What are the purple edges of digital photos? The purple edge of the digital camera refers to the digital camera in the process of capture due to the contrast between the object, the high light and low light parts of the spot at the junction of the phenomenon is the

rounding rule is "every two in one", the borrow rule is "borrowing one as two", which was found by the 18th century German mathematical philosophy master Leibniz.Seven: CPUCPU is the central processing Unit, which has the function of arithmetic and controller. Is the most important one in a computer, so we need to know more about it.Eight: cacheCache is small capacity when fast memory, used to store the most recently used information, has avoided access to RAM.Nine: Other computersPC, MAC, mobi

Data recovery software as a kind of emergency equipment in general, you may not be involved, but no one is perfect, people always make mistakes, mistakenly deleted in the computer operation is not uncommon, then the data recovery software, such as saving straws can solve the immediate problem. There are so many data recovery software that it is not easy to find the right part of the vast software heap. Not long ago, I mistakenly deleted a digital

more functions to enhance system display and management. The web-based digital notice player supports 1080 P Full HD video playback and simultaneous display of dual-screen images. It also supports HTML, javascript, Flash, and other web languages, these new functions can be used in multimedia public display systems for LINUX-based products.

tool in Windows, the deleted files can be restored in just a few seconds ". It is because it is "small" that the capacity is 355KB, and no installation is required that I download it first. The software interface is simple and easy to use. However, it was found that the speed was very slow, especially the second scan, which was simply intolerable and the file recovery effect was not ideal. The files that have been overwritten and that have not been overwritten cannot be distinguished, not all

1 Concepts of digital certificates1, asymmetric encryption algorithm is used to encrypt/decrypt data to ensure the confidentiality of data.2, the digital Signature algorithm is used to sign/Verify data to ensure the integrity and anti-repudiation of data.3, the Message digest algorithm is used to digest the digital cer

order to ensure the real-time and image quality of digital video transmission based on the network, the choice of transport layer protocol is the key to the entire design and implementation. The Internet uses two transmission protocols on the IP layer: one is the transmission control protocol TCP (Transmission Control Protocol), which is a connection-oriented network protocol; another is the user data Datagram Protocol (UDP), which is a connectionl

Yesterday, in the company's code, I saw that the post build step of a VC project will use signtool to add a digital signature to the EXE generated by the project, A part of the EXE code calls the Windows API winverifytrust to verify the digital signature of the exe. Just a few days ago, I started to use digital signatures with curiosity. After a day, I finally le

in 3, the P-frame continuous GraphIMG (progressiveStrip can be used for intra-frame encoding (I image strips), so that the complete I frame is no longer needed after the initial frame, it can also reduce the problems of discarded I frames and damaged images.

sharpening (such as the Laplace method).Many algorithms in the enhanced processing are coincident with the noise reduction algorithm in image restoration. Now the smoothing algorithm of preserving edge (or texture structure) belongs to the research hotspot. Skin-rejuvenation algorithms like those in a beauty camera are based on this. More common bilateral filtering (see http://blog.csdn.net/baimafujinji/article/details/41598455 for the code I gave)TV

The knowledge of this article is excerpted from: Wang Mitiu. On the storage format of digital graphic image. Journal of Hunan Rtvu, 2004 (1) A few basic concepts about digital graphic images L, pixel (pixel) A pixel is the abbreviation of a graphical unit (pictureelement), which is the complete unit of the smallest bitmap. There are two properties of a pixel: one

cable requirements, in the actual network applications people would like to know the transmission bandwidth should meet what kind of requirements. When analyzing cable, physical bandwidth (0~100mhz) and data transmission bandwidth (0~100MBIT/S) are two completely different concepts. From Shannon's theorem, we can see the relationship between physical bandwidth and data transmission bandwidth: C=BLOG2 (1+s/n) Where c is the available link speed, B i
