However, storing multimedia outside the database makes it harder to provide database functionality, such as indexing on the basis of actual multimedia data content It can also lead to inconsistencies, such as a le that is noted in the database, but whose contents are missing, or vice versa It is therefore desirable to store the data themselves in the database Several issues have to be addressed if multimedia data are to be stored in a database The database must support large objects, since multimedia data such as videos can occupy up to a few gigabytes of storage Many database systems do not support objects larger than a few gigabytes Larger objects could be split into smaller pieces and stored in the database Alternatively, the multimedia object may be stored in a le system, but the database may contain a pointer to the object; the pointer would typically be a le name The SQL/MED standard (MED stands for Management of External Data), which is under development, allows external data, such as les, to be treated as if they are part of the database With SQL/MED, the object would appear to be part of the database, but can be stored externally We discuss multimedia data formats in Section 2341 The retrieval of some types of data, such as audio and video, has the requirement that data delivery must proceed at a guaranteed steady rate Such data are sometimes called isochronous data, or continuous-media data For example, if audio data are not supplied in time, there will be gaps in the sound If the data are supplied too fast, system buffers may over ow, resulting in loss of data We discuss continuous-media data in Section 2342 Similarity-based retrieval is needed in many multimedia database applications For example, in a database that stores ngerprint images, a query ngerprint image is provided, and ngerprints in the database that are similar to the query ngerprint must be retrieved Index structures such as B+ -trees and R-trees cannot be used for this purpose; special index structures need to be created We discuss similarity-based retrieval in Section 2343. c# ocr library open sourceFeb 26, 2018 · In this article, we are going to learn how to use Google Vision API with ASP. ... optical character recognition (OCR), and tagging of explicit content. .....

Because of the large number of bytes required to represent multimedia data, it is essential that multimedia data be stored and transmitted in compressed form For image data, the most widely used format is JPEG, named after the standards body that created it, the Joint Picture Experts Group We can store video data by encoding each frame of video in JPEG format, but such an encoding is wasteful, since successive frames of a video are often nearly the same The Moving Picture Experts Group has developed the MPEG series of standards for encoding video and audio data; these encodings exploit commonalities among a sequence of frames to achieve a greater degree of compression The MPEG-1 standard stores a minute of 30-frameper-second video and audio in approximately 125 megabytes (compared to approximately 75 megabytes for video in only JPEG) However, MPEG-1 encoding introduces some loss of video quality, to a level roughly comparable to that of VHS video tape c# free ocr libraryMar 7, 2016 · In this article I am going to show how to do OCR using Tesseract in C#. ...

The McGraw Hill Companies, 2001 dialog box (see Figure 10-3) The MPEG-2 standard is designed for digital broadcast systems and digital video disks (DVD); it introduces only a negligible loss of video quality MPEG-2 compresses 1 minute of video and audio to approximately 17 megabytes Several competing standards are used for audio encoding, including MP3, which stands for MPEG-1 Layer 3, RealAudio, and other formats 2 s3 . c# ocr api open sourceHigh performance, royalty-free C# .NET OCR and barcode recognition on Windows 32bit and 64bit. ...

This article ... The most important types of continuous-media data are video and audio data (for example, a database of movies) Continuous-media systems are characterized by their real-time information-delivery requirements: Data must be delivered suf ciently fast that no gaps in the audio or video result Data must be delivered at a rate that does not cause over ow of system buffers Synchronization among distinct data streams must be maintained This need arises, for example, when the video of a person speaking must show lips moving synchronously with the audio of the person speaking To supply data predictably at the right time to a large number of consumers of the data, the fetching of data from disk must be carefully coordinated Usually, data are fetched in periodic cycles In each cycle, say of n seconds, n seconds worth of data is fetched for each consumer and stored in memory buffers, while the data fetched in the previous cycle is being sent to the consumers from the memory buffers The cycle period is a compromise: A short period uses less memory but requires more disk arm movement, which is a waste of resources, while a long period reduces disk arm movement but increases memory requirements and may delay initial delivery of data When a new request arrives, admission control comes into play: That is, the system checks if the request can be satis ed with available resources (in each period); if so, it is admitted; otherwise it is rejected Extensive research on delivery of continuous media data has dealt with such issues as handling arrays of disks and dealing with disk failure See the bibliographical references for details Several vendors offer video-on-demand servers Current systems are based on le systems, because existing database systems do not provide the real-time response that these applications need The basic architecture of a video-on-demand system comprises: Video server Multimedia data are stored on several disks (usually in a RAID con guration) Systems containing a large volume of data may use tertiary storage for less frequently accessed data Terminals People view multimedia data through various devices, collectively referred to as terminals Examples are personal computers and televisions attached to a small, inexpensive computer called a set-top box.
