- Сжатие
- Сжатие (данных), уменьшение размеров файла изображения. см. также lossy и non-lossy. процесс упаковки данных с целью уменьшения занимаемого ими пространства на накопителе
- Компрессия, сжатие
- The reduction of volume of a vapor or gas by mechanical means.
- Digital video pictures can be compressed with a number of techniques. these include: jpeg and jpeg-2000 (for still images), m-jpeg and mpeg (for moving pictures).
- The reduction in gain at one level of a picture signal with respect to the gain at another level of the same signal.
- A digital photograph creates an image file that is huge, a low-resolution 640x480 image has 307,200 pixels. if each pixel uses 24 bits (3 bytes) for true color, a single image takes up about a megabyte of storage space. to make image files smaller almost every digital camera uses some form of compression. see the jpg entry below.
- The application of any of several techniques that reduce the amount of information required to represent that information in data transmission. this method reduces the required bandwidth and/or memory.
- A method of reducing the size of a digital image file to free up the storage capacity of memory cards and hard drives. compression technologies are distinguished from one another by whether or not they remove detail and color from the image. lossless technologies compress image data without removing detail, while "lossy" technologies compress images by removing some detail. joint photographic experts group (jpeg) is a lossy compression format supported by jpeg, pdf and postscript language file formats. most video formats are also lossy formats. tiff files are not and, as such, are far more stable than jpegs and other lossy file formats.
- Reducing the number of bits needed to encode a digital signal, typically by eliminating long strings of identical bits or bits that do not change in successive sampling intervals (e.g., video frames).
- A digital photograph creates an image file that is enormous. to enable image files to become smaller and more manageable cameras employ some form of compression such as jpeg. raw and tiff files have no compression and take up more space.
- 1. the act of squeezing or pressing the first-aider applied compression to the chest of the casualty. 2. a serious condition in which the brain is compressed by blood or cerebrospinal fluid accumulating in it or by a fractured skull

- A reduction of the time available for a scheduled storyboard to reach its final state.
- A way of making files smaller, either to fit into restricted storage space or to speed up transmission over the internet. popular compression standards include- jpeg- and- gif- for pictures,- mp3for music files,- mpeg, mp4, avi- and- mov- for movie footage, and- zip- for just about everything else.

compression of morbidity |
|
|
compression of morbidity hypothesis | Prof. james f. fries, m.d., a stanford university school of medicine rheumatologist, established the "compression of morbidity" hypothesis in 1980. he suggested that if the onset of disability due to age-related diseases and conditions could be postponed to a greater degree than average life expectancy would increase, then total lifetime disability could be compressed into a shorter average period. the cumulative average lifetime disability would also be reduced. |

compression ratio | - Степень сжатия
- The ratio determined by dividing the discharge pressure by the suction pressure in psi (pounds per square inch).
- In an internal combustion engine, the ratio of the volume of combustion space at bottom dead center to that at top dead center.
- Степень сжатия [повышения давления]
- Степень сжатия; коэффициент сжатия
- Also known as `slope`, in a compressor/limiter, the ratio of change in input level (in db) to the change in output level (in db). for example, a 4:1 ratio means that for every 4db change in input level, the output level changes 1db.
- The ratio of the uncompressed size to the compressed size of a stored unit of data.
- In a reciprocating engine, the ratio of cylinder plus combustion chamber volume at the bottom of the stroke (at moment of greatest volume) to the volume at top of stroke, when the volume is least. note that compression ratio is a volumetric ratio and not a pressure ratio.
- The ratio between the largest and smallest possible volumes in the cylinder of an internal-combustion engine. for example, a compression ratio of 9:1 means the piston will compressed the air/fuel mixture into a space that is nine times smaller than the maximum cylinder volume.
