Abstract: A system including primary camera(s) arranged on vehicle that is employed for surveying real-world environment; secondary camera(s) coupled to steering unit(s) that is arranged on vehicle; geolocation sensor that, in operation, detects geographical location and orientation of vehicle; and processor(s) configured to receive primary image(s) captured by primary camera(s); process primary image(s) to detect asset(s) (P1, P2, P3, P4, X, Y) and location and orientation of asset(s); control steering unit(s) to adjust pose of secondary camera(s) based on location and orientation of asset(s) and geographical location and orientation of vehicle, for enabling secondary camera(s) to capture secondary image(s) of asset(s); receive secondary image(s) captured by secondary camera(s); process secondary image(s) to detect anomalous phenomena in asset(s); and locate anomalous phenomena based at least on location and orientation of asset(s).

Abstract: The pertinence of digital image material is analysed in respect of matching a given reference. A color of the reference constitutes a reference record in a perceptual color space. Pixels of a piece of digital image material are converted into the perceptual color space, and labelled according to how their converted pixel values belong to environments of principal colors in the perceptual color space. A connected set of pixels is selected that have at least one common label. A subset of the connected set of pixels is determined, so that the pixel(s) of the subset are those for which a color similarity distance to the reference record is at an extremity. For the connected set of pixels, a representative color is selected among or derived from the color or colors of the pixels that belong to the subset.
