However, the challenges of robust tracking come from uncertain and dynamic conditions of speed, occlusion, deformation, illumination variation, background clutter, real-time restriction, etc.
Rearrange and subgroup the data to study other sources of variation (background and contextual variables).
This parameter provides an estimate of the variance due to experimental variation (background variance) since theoretically no differences in gene expression should be noted by using the same material.
Since microarray technology at the present has progressed towards a point where technical variation, background noise, and a lack of accuracy have greatly improved, the critical step has moved towards the preparation of the RNA sample.
Comparison of variation among mth allele backgrounds supports allelism, as variation in the wild-type background was not greater than variation in the mutant backgrounds (Table 2).
The new method accounts for the functional impact of mutations on proteins, variation in background mutation rate among tumors and the redundancy of the genetic code.
Furthermore, some other complex problems are also considered such as light variations, poor background, etc.
Note, however, that invariance under variations of background variables is neither necessary nor sufficient for being minimally invariant (cf. Woodward 2003, 248; Hitchcock & Woodward 2003, 7f).
Furthermore, an internal control was also successfully employed in these probes to improve imaging reliability by accounting for cell-to-cell variations and background.
The probabilistic visual tracking methods using color histograms have been proven to be robust to target model variations and background illumination changes as shown by the recent research.
