Spatio-Temporal Complexity in Nonlinear Image Processing
نویسنده
چکیده
Ahsfruct -This is a pictorial survey of pattern dynamics in video feedback and in related numerical models. After a short introduction to video feedback apparatus and concepts from dynamical systems theory, a range of phenomena are presented, from simple attractor types to homogeneous video turbulence. Examples of complex behavior include symmet~y-locking chaos, spatial amplification of fluctuations in open flows, dislocations, phyllotaxis, spiral waves, and noise-driven oscillations. Video experiment5 on nonlinear transformations of the plane are also described. The suney closes with a discussion of the relationship between dgnamical systems and nonlinear, iterative image processing.

An Artificial Neural Network for Spatio-Temporal Bipolar Patterns: Application to Phoneme Classification
An artificial neural network is developed to recognize spatio-temporal bipolar patterns associatively. The function of a formal neuron is generalized by replacing multiplication with convolution, weights with transfer functions, and thresholding with nonlinear transform following adaptation. The Hebbian learning rule and the delta learning rule are generalized accordingly, resulting in the lear...
متن کاملEfficient Online Spatio-Temporal Filtering for Video Event Detection
We propose a novel spatio-temporal filtering technique to improve the per-pixel prediction map, by leveraging the spatio-temporal smoothness of the video signal. Different from previous techniques that perform spatio-temporal filtering in an offline/batch mode, e.g., through graphical model, our filtering can be implemented online and in real-time, with provable lowest computational complexity....
متن کاملExplaining Optical Flow Events with Parameterized Spatio-Temporal Models
A spatio-temporal representation for complex optical flow events is developed that generalizes traditional parameterized motion models (e.g. afine). These generative spatio-temporal models may be non-linear or stochastic and are event-specijic in that they characterize a particular type of object motion (e.g. sitting or walking). Within a Bayesian framework we seek the appropriate model, phase,...
متن کاملFast Generation of Digital Video Holograms Using a Spatio-temporal Sampling Scheme and Gpus
v High complexity of computer-generated holography (CGH) is already well known to researchers in the field of optical engineering. Therefore, in order to improve the practicability of CGH, it should be substantially reduced. In this paper, we proposed a method that can quickly generate digital video holograms using a spatiotemporal sampling scheme and general purpose graphic processing units (G...
متن کاملThe network behind spatio‐temporal patterns: building low‐complexity retinal models in CNN based on morphology, pharmacology and physiology
In this paper, a vertebrate retina model is described based on a cellular neural network (CNN) architecture. Though largely built on the experience of previous studies ([31]-[34], [36]-[39], [41]) the CNN computational framework is considerably simplified: first order RC cells are used with space-invariant nearest neighbor interactions only. All nonlinear synaptic connections are monotonic cont...
