Brief introductionFREAK algorithm is a feature extraction algorithm proposed in the 2012 CVPR freak:fast Retina KeyPoint, and is also a binary feature description operator.It is very similar to the brisk algorithm, the personal feel is in the brisk algorithm improvement, about brisk algorithm, see the previous blog: Brisk feature extraction algorithm. Freak still has scale invariance, rotational invariance, noise robustness and so on.Freak algorithmSampling modeIn the brisk algorithm, the sampli

Layered, new third board layered 1. UI (user layer), BLL (business logic layer), DAL (data access layer ).The UI is used for display, such as some display styles and interface design. BLL is used to handle business logic problems. DAL deals with databases. 2. Data Access Layer: This Layer is at the bottom Layer and is responsible for interacting with the database, also known as the Data Access Layer (DAL ). Presentation Layer: This Layer directly

TermsBefore discussing DB2's support for 32-bit and 64-bit, we will first view and understand some of the terms and important concepts involved in the context of this article. This is very important: Platform:The basic technologies of computer hardware and operating systems define how a computer runs and what kind of software can run on it. Hardware:Computer and its related architecture. Operating System:Controls computer hardware and allows other applications and users to use computer softw

Prototype = "instance of direct parent class" This is different from a language like Delphi: the essence of maintaining the prototype chain is to execute code rather than declaration. So what is the significance of "execution rather than Declaration? Javascript compilation may occur. This process mainly deals with "syntax errors" and "LanguageStatement and Conditiona

The page is cached by cpu2 again (the page has been put back to the partial linked list in the previous step ).In this case, page-> freelist may be accessed by the CPU cpu1 and cpu2.

that deals with page cache and disk drives. The usage of system page cache can be analyzed through the monitoring data of buffer/cache. From the perspective of file reading and writing, buffer is mostly used to cache file management information, such as directory location and inode information. The cache caches the file content. Since the CPU cannot directly process data on peripherals, the buffer is used to mark descriptions such as the locati

. When a user's process can meet the user's requirements for device requests, it will return the requested data. If not, you can call the request function to perform actual I/O operations. block devices are designed for disks and other slow devices to avoid excessive CPU time consumption. As mentioned, the user process deals with the actual hardware through the device file. Each device file has its File Attribute (C/B), which indicates that the charac
