Pursuing this logic further, his teams also transformed more complex measurements, which take into account several parameters simultaneously, into video sequences. In this case, standard video-processing filters were used. These approaches are, by definition, less expensive than adding more measuring instruments. The performance-enhancement technique works because there is a high level of similarity and redundancy in the multidimensional information measured by distributed fiber sensors.
