Support for 4:4:4 chroma subsampling for compatibility with high dynamic range (HDR) displays
For workflows where color precision is needed, the Makito X4 offers 4:2:2 chroma subsampling to ensure that color fidelity can be maintained, and artefacts prevented, in downstream workflows.
(1), p is the level of subsampling, M is the shorter border of the original image and N is set to 512 to balance the time complexity and the detection results.
After each convolution layer follows subsampling layer.
KEY WORDS: criteria pollutants, hierarchical Bayes, multicity analyses, spline smoothers, subsampling bootstrap.
Subsampling the data on daily larval supply generated more than one estimate of supply for each year, yielding many possible combinations of annual estimates.
We have demonstrated numerically that the precision of the estimates of prey size in gut contents is sensitive to the size of the subsamples, which is in accordance with the analytical predictions of subsampling theory (Hansen et al., 1993).
The system is also useful for subsampling from brass sleeves or soil jars.
Disclosure control techniques applied to the tax model file for public-use include suppression, global and local recoding, top coding, rounding, subsampling, and microaggregation (replacing reported data by the average value of a sorted cluster of three values).
Examples include the practices of not collecting replicate samples, subsampling and/or splitting of collected samples, and identifying collected specimens only to taxonomic family.
Cores were extruded in the field and subdivided into 2-cm segments of which each was homogenized and stored at 4 C before subsampling. Cores were dated by lead-210 with ages determined by the constant rate of supply model (Appelby and Oldfield, 1978).
He restricted selection to small estates and older decedents, and then took only persons with German or Irish names, to test "culture." Apparently dissatisfied with the results of subsampling, the author eliminated most of the males and some of the females "to minimize the differential visibility of male and female decedents" (71).
