In order to accommodate long-term time-variable gravity variations not included in the background geopotential model, we assess the feasibility of using DORIS data to observe local mass variations using point mascons.
Gathering background observations over long-term sequences has the advantage that lighting variation can be included in the background training set.
It should be pointed out that possibly influencing factors, such as "non-neoplastic" lesions (e.g., major infarctions in MRI, cysts), should not be included in the background VOI.
Interesting is also that Jodoin et al. demonstrate their algorithm on video sequences of water surfaces, in which the regular surface waves are included in the background; whereas extraordinary events such as ripples from a stone thrown in the water, or a passing boat, are detected as abnormal events.
"We need to look at the full range of mental health issues, from early detection and treatment, to civil commitment laws, to privacy laws that needlessly prevent mental health records from being included" in the background check system, he said.
For example, polypeptide coding sequences are considered background, and the distribution of the sequence of bases is determined by the effect of the polypeptide sequence on evolutionary fitness; something which would require more knowledge about biological function than is available, and is too complex to include in the background model.
