Time-Recursive Velocity-Adapted Spatio-Temporal Scale-Space Filters
This paper presents a theory for constructing and computing velocity-adapted scale-space lters for spatio-temporal image data. Starting from basic criteria in terms of time-causality, time-recursivity, locality and adaptivity with respect to motion estimates, a family of spatio-temporal recursive lters is proposed and analysed. An important property of the proposed family of smoothing kernels i...
متن کاملDense scale selection over space, time and space-time
Scale selection methods based on local extrema over scale of scale-normalized derivatives have been primarily developed to be applied sparsely — at image points where the magnitude of a scale-normalized differential expression additionally assumes local extrema over the domain where the data are defined. This paper presents a methodology for performing dense scale selection, so that hypotheses ...

متن کاملNon-differentiable space-time and scale relativity∗
The theory of scale relativity consists of developing the consequences of the withdrawal of the hypothesis of space-time differentiability. Spacetime acquires a fractal geometry, namely, it becomes explicitly dependent on the observation scale. The space-time resolutions are redefined as characterizing the state of scale of the reference system, then we set the principle of scale relativity, ac...
متن کاملvelocity addition and the relativity of space and time intervals
A thought experiment first proposed by Sartori is analysed using the parallel velocity addition formula of special relativity. The spatial and proper-time intervals between some similarly defined spatial coincidence events are found to be widely different in different inertial frames. This relativity of space and time intervals is quite distinct from the well-known time-dilatation and length co...
