Sparse Coding of Time-varying Natural Images
We show how the principle of sparse coding may be applied to learn the forms of structure occurring in time-varying natural images. A sequence of images is described as a linear superposition of space-time functions , each of which is convolved with a time-varying coeecient signal. When a sparse, independent representation is sought over the coeecients, the basis functions that emerge are space...
متن کاملLearning sparse, overcomplete representations of time-varying natural images
I show how to adapt an overcomplete dictionary of spacetime functions so as to represent time-varying natural images with maximum sparsity. The basis functions are considered as part of a probabilistic model of image sequences, with a sparse prior imposed over the coefficients. Learning is accomplished by maximizing the log-likelihood of the model, using natural movies as training data. The bas...
متن کاملStatistics of Natural Time-Varying Images
Natural time-varying images possess substantial spatiotemporal correlations. We measure these correlations | or equivalently the power spectrum | for an ensemble of more than a thousand segments of motion pictures, and we nd signi cant regularities. More precisely, our measurements show that the dependence of the power spectrum on the spatial frequency, f , and temporal frequency, w, is in gene...
متن کاملCoding Time-Varying Signals Using Sparse, Shift-Invariant Representations
A common way to represent a time series is to divide it into shortduration blocks, each of which is then represented by a set of basis functions. A limitation of this approach, however, is that the temporal alignment of the basis functions with the underlying structure in the time series is arbitrary. We present an algorithm for encoding a time series that does not require blocking the data. Th...
