Esempi di utilizzo di SUBSAMPLING in una frase

• when one wishes to encode the 24-bit colour RGB (40, 40, 40) with 16 bits (a problem common to subsampling).
• Like most common video codecs, Theora used chroma subsampling, block-based motion compensation and an 8-by-8 DCT block.
• Chroma subsampling is the practice of encoding images by implementing less resolution for chroma information than for luma information, taking advantage of the human visual system's lower acuity for color differences than for luminance.
• 26x compressed formats, although compressed formats for consumer applications usually use chroma subsampling reduced from the 4:2:2 sampling specified in Rec.
• A block can consist of 4 luminance values (grayscale) or of 4 luminance and 2 chrominance values (4:2:0 chroma subsampling).
• SMPTE 356M is a SMPTE specification for a professional video format, it is composed of MPEG-2 video composed of only I-frames and using 4:2:2 chroma subsampling.
• During compression, each frame's luminance channel is subsampled at 1440 x 1080, while the chrominance channel is subsampled at 480 x 1080, meaning 3:1:1 chroma subsampling.
• Internal support for RGB24, RGBA32, YUVA, YUV, YUV422, YUV420 (jpeg and mpeg), YUYV, YUV411, and UYVY palettes; one step conversion with chroma super and subsampling is implemented.
• A camera with the minimum requirements typically being the inclusion of three CCDs and relatively low-compression analog recording or digital recording capability with little or no chroma subsampling, and the ability to be genlocked.
• While subsampling was originally proposed for the case of independent and identically distributed (iid) data only, the methodology has been extended to cover time series data as well; in this case, one resamples blocks of subsequent data rather than individual data points.
• In univariate problems, it is usually acceptable to resample the individual observations with replacement ("case resampling" below) unlike subsampling, in which resampling is without replacement and is valid under much weaker conditions compared to the bootstrap.
• The 21 megapixel sensor is downsampled to HD resolution by only using every third line and 4:2:0 chroma subsampling, leading to concern about Moiré patterns in recorded video.
• Typical components include image sensor corrections (including debayering or applying a Bayer filter), noise reduction, image scaling, gamma correction, image enhancement, colorspace conversion (between formats such as RGB, YUV or YCbCr), chroma subsampling, framerate conversion, image compression/video compression (such as JPEG), and computer data storage/data transmission.
• Frame compatible: Pixel subsampling like Side by Side, Checkerboard, Quincunx and Color shifting like Anaglyph.
• SENSIO® Hi-Fi 3D is a set of technologies, composed of the SENSIO® 3D Encoder and the SENSIO® 3D Decoder, which provides maximum fidelity to the original 3D image through a unique and established method of quincunx subsampling combined with reconstruction algorithms that interpolate the missing data to a high level of accuracy.
• They perform a large number of tasks: Bayer filtering, demosaicing, image sensor corrections/dark-frame subtraction, image noise reduction, image sharpening, image scaling, gamma correction, image enhancement/Active D-Lighting, colorspace conversion, chroma subsampling, framerate conversion, lens distortion/chromatic aberration correction, image compression/JPEG encoding, video compression, display/video interface driving, digital image editing, face detection, audio processing/compression/encoding and computer data storage/data transmission.
• Robinson has numerous publications including, "Widespread changes in mRNA stability contribute to quiescence-specific gene expression patterns in a fibroblast model of quiescence", "broom: An R package for converting statistical analysis objects into tidy data frames", "A nested parallel experiment demonstrates differences in intensity-dependence between RNA-seq and microarrays", "subSeq: Determining appropriate sequencing depth through efficient read subsampling", "Design and Analysis of Bar-seq Experiments", and "OASIS: an automated program for global investigation of bacterial and archaeal insertion sequences".
• To address this issue, Chen, Dou, and Qiao proposed a non-parametric multivariate test method using ensemble subsampling nearest neighbors (ESS-NN) for imbalanced data.
