Exempel på hur man kan använda DCT i en mening

• Motion compensation is one of the two key video compression techniques used in video coding standards, along with the discrete cosine transform (DCT).
• A discrete cosine transform (DCT) expresses a finite sequence of data points in terms of a sum of cosine functions oscillating at different frequencies.
• It was developed from 1997 to 2000 by a Joint Photographic Experts Group committee chaired by Touradj Ebrahimi (later the JPEG president), with the intention of superseding their original JPEG standard (created in 1992), which is based on a discrete cosine transform (DCT), with a newly designed, wavelet-based method.
• Like most common video codecs, Theora used chroma subsampling, block-based motion compensation and an 8-by-8 DCT block.
• The DST is related to the discrete cosine transform (DCT), which is equivalent to a DFT of real and even functions.
• This was achieved with features such as a reduced-complexity integer discrete cosine transform (integer DCT), variable block-size segmentation, and multi-picture inter-picture prediction.
• During the late 1980s, a number of companies began experimenting with the much more efficient DCT compression for video coding, with the CCITT receiving 14 proposals for DCT-based video compression formats, in contrast to a single proposal based on vector quantization (VQ) compression.
• The DCT is the most widely used lossy compression algorithm, the basis for multimedia formats such as JPEG, MPEG and MP3.
• Other types of automatic transmissions include continuously variable transmissions (CVT), automated manual transmissions (AMT), and dual-clutch transmissions (DCT).
• However, it was not possible to practically implement such an interactive VOD service until the adoption of DCT and ADSL technologies made it possible in the 1990s.
• The distal convoluted tubule (DCT) is a portion of kidney nephron between the loop of Henle and the collecting tubule.
• An important development in digital image compression technology was the discrete cosine transform (DCT), a lossy compression technique first proposed by Nasir Ahmed in 1972.
• Musically, the album veered away from the classic DCT formula and deeper into the hip-hop dance theme begun on Delicious and Love Unlimited.
• The command-line program jpegtran provides several features for reformatting and recoding the representation of the DCT coefficients, for transformation of actual image data and for discarding auxiliary data in JPEG files, respectively.
• Cinepak is based on vector quantization, which is a significantly different algorithm from the discrete cosine transform (DCT) algorithm used by most current codecs (in particular the MPEG family, as well as JPEG).
• Streaming services started as a result of two major technological developments: MPEG (motion-compensated DCT) video compression and asymmetric digital subscriber line (ADSL) data communication.
• The portfolio ranged from classic manual transmissions, automated manual transmissions, and automatic transmissions based on dual-clutch transmission (DCT) technology to various hybridization solutions, range extender systems, and purely electric drivetrains.
• Bendroflumethiazide is a thiazide diuretic which works by inhibiting sodium reabsorption at the beginning of the distal convoluted tubule (DCT).
• The bridge was rebuilt and enlarged to accommodate a second High-Angle Control System aft of the Director-Control Tower (DCT) on top of the bridge, her single four-inch AA guns were replaced with twin-gun mounts for Mark XVI guns of the same calibre and a pair of octuple mounts for two-pounder "pom-poms" were added abreast her aft superstructure.
• Bez was the first director of BMW Technik GmbH (BMW Technology), developing a BMW V8 concept engine which helped to replace the big inline six-cylinder with an eight-cylinder engine, a DCT, voice activated car systems as well as the world's first acoustic wind tunnel and the responsibility for the design of the BMW Z1, a leading concept in its time for modularity, material, aerodynamics and safety.
