y2 cbcr造句

例句与造句

1. Y2 CbCr color spaces are defined by a mathematical coordinate transformation from an associated RGB color space.
2. In digital-video and still-image color spaces such as Y2 CbCr, the luma and chrominance components are digital sample values.
3. So proper conversion of Y2 CbCr from one form to the other is not just a matter of inverting one matrix and applying the other.
4. Instead of Y2 UV, Y2 CbCr was used as the standard format for ( digital ) common video compression algorithms such as MPEG-2.
5. For color spaces that use luma, such as Y2 UV or Y2 CbCr ( where Y2 represents luma ), computation of relative luminance can still be done.
6. It's difficult to find y2 cbcr in a sentence. 用y2 cbcr造句挺难的
7. This form of Y2 CbCr is used primarily for older standard-definition television systems, as it uses an RGB model that fits the phosphor emission characteristics of older CRTs.
8. The professional CCIR 601 digital video format also uses Y2 CbCr at the common chroma subsampling rate of 4 : 2 : 2, primarily for compatibility with previous analog video standards.
9. Digital television and DVDs preserve their compressed video streams in the MPEG-2 format, which uses a full Y2 CbCr color space, although retaining the established process of chroma subsampling.
10. YCbCr and Y2 CbCr are a practical approximation to color processing and perceptual uniformity, where the primary colors corresponding roughly to red, green and blue are processed into perceptually meaningful information.
11. If the underlying RGB color space is absolute, the Y2 CbCr color space is an absolute color space as well; conversely, if the RGB space is ill-defined, so is Y2 CbCr.
12. If the underlying RGB color space is absolute, the Y2 CbCr color space is an absolute color space as well; conversely, if the RGB space is ill-defined, so is Y2 CbCr.
13. Y2 CbCr is often confused with the YUV color space, and typically the terms YCbCr and YUV are used interchangeably, leading to some confusion; when referring to signals in video or digital form, the term " YUV " mostly means " Y2 CbCr ".
14. Y2 CbCr is often confused with the YUV color space, and typically the terms YCbCr and YUV are used interchangeably, leading to some confusion; when referring to signals in video or digital form, the term " YUV " mostly means " Y2 CbCr ".
15. Y2 CbCr is used to separate out a luma signal ( Y2 ) that can be stored with high resolution or transmitted at high bandwidth, and two chroma components ( C B and C R ) that can be bandwidth-reduced, subsampled, compressed, or otherwise treated separately for improved system efficiency.
16. In fact, when Y2 CbCr is designed ideally, the values of K B and K R are derived from the precise specification of the RGB color primary signals, so that the luma ( Y2 ) signal corresponds as closely as possible to a CIE 1931 measurements of the response of the human visual system to color stimuli ).
