Derivatives in scale space [PDF]
, 1996 Various derivatives (1st to 4th order) describe different signal characters in scale space: the first derivative represents signal variation which can be used for coding; the second derivative characterizes the size of signal local structure and can be used for adaptive smoothing; the third and fourth order derivatives relate zero-crossing(or other ...

Multi-pyramid image spatial structure based on coarse-to-fine pyramid and scale space
CAAI Transactions on Intelligence Technology, 2018 Coarse-to-fine pyramid and scale space are two important image structures in the realm of image matching. However, the advantage of coarse-to-fine pyramid is neglected as the pyramid structure is usually constructed with the down sampling method in scale

Interest point detection and scale selection in space-time [PDF]
, 2003 . Several types of interest point detectors have been proposed for spatial images. This paper investigates how this notion can be generalised to the detection of interesting events in space-time data.
