convolutions, plural;
  1. A coil or twist, esp. one of many
    • - crosses adorned with elaborate convolutions
  2. A thing that is complex and difficult to follow
    • - the convolutions of farm policy
  3. A sinuous fold in the surface of the brain

  4. The state of being coiled or twisted, or the process of becoming so
    • - the flexibility of the polymer chain allows extensive convolution
  5. A function derived from two given functions by integration that expresses how the shape of one is modified by the other

  6. A method of determination of the sum of two random variables by integration or summation

  1. (convolution) whirl: the shape of something rotating rapidly
  2. (convolution) gyrus: a convex fold or elevation in the surface of the brain
  3. (convolution) the action of coiling or twisting or winding together
  4. (Convolution) In mathematics and, in particular, functional analysis, convolution is a mathematical operation on two functions f and g, producing a third function that is typically viewed as a modified version of one of the original functions. Convolution is similar to cross-correlation. ...
  5. (Convolution (computer science)) In computer science, specifically formal languages, convolution (sometimes referred to as zip) is a function which maps a tuple of sequences into a sequence of tuples.
  6. (CONVOLUTION) The smallest flexible unit of a bellows. The total movement capacity of a bellows is proportional to the number of convolutions.
  7. (convolution) an image processing technique in which each pixel is altered by some function of the surrounding pixels; different functions produce a variety of effects.
  8. (Convolution) A mathematical process. To convolve a 128-point HRTF with a sound wave, both functions must be sampled at the same rate, e.g. 44,100 samples per second. The 128 HRTF samples then cover a time period of 2.9 milliseconds. The HRTF samples are first flipped in time. ...
  9. (Convolution) An abrupt rotation of the hair shaft that can occur naturally, from disease, or as a result of mechanical force.
  10. (Convolution) On a bellow type air actuator, that part of the flexible member forming an annular protrusion larger than the O.D. of the end retainers or bead rings.(058)
  11. (Convolution) The annular or helical flexing member in corrugated or strip wound hose.
  12. (Convolution) using a digital recording and applying DSP signal processing to “imprint” an impulse response on a source signal. For example, multiplying and adding to the samples of an instrument or voice the acoustical impulse response of a hall as though the source had been recorded in that hall.
  13. (convolution) Pointwise multiplication of each kxk neighborhood of a digital image by a kxk kernel of convolution weights
  14. (convolution) The process of transforming the value of a pixel, or a field of pixels, based on a mathematical formula. Convolution is used to alter the color of an image (filtering), or to re-encode the data (compression).
  15. (convolution) description of a duct having spiral or helical ridges formed to enhance flexibility.
  16. (convolution) the corrogated appearance of the cortex, includes both gyri and sulci
  17. (convolution) the mathematical link between the input seismic signal, the transfer function, and the output signal. Usually performed in the frequency domain.
  18. Convolution is when one function modifies another, such as blurring from poor seeing modifying the point spread function of a star.
