چکیده

Dynamic textures (DTs) are pseudo periodic data on a space × time support, that can represent many natural phenomena captured from video footages. Their modeling and recognition useful in applications of computer vision. This paper presents an approach for DT analysis combining graph-based description the Complex Network framework, learned representation Randomized Neural (RNN) model. First, directed graph with only one parameter (radius) is used to both motion appearance DT. Then, instead using classical measures as features, descriptor RNN, trained predict gray level pixels local topological graph. The weight vector output layer RNN forms descriptor. Several structures experimented RNNs, resulting networks final characteristics single hidden 4, 24, or 29 neurons, input layers sizes 4 10, meaning 6 different RNNs. Experimental results conducted Dyntex++ UCLA datasets show high discriminatory power our descriptor, providing accuracy 99.92%, 98.19%, 98.94% 95.03% UCLA-50, UCLA-9, UCLA-8 databases, respectively. These outperform various literature approaches, particularly UCLA-50. More significantly, method competitive terms computational efficiency size. It therefore good option real-time dynamic texture segmentation, illustrated by experiments videos acquired moving boat.

Graph Representation Learning and Graph Classification

Many real-world problems are represented by using graphs. For example, given a graph of a chemical compound, we want do determine whether it causes a gene mutation or not. As another example, given a graph of a social network, we want to predict a potential friendship that does not exist but it is likely to appear soon. Many of these questions can be answered by using machine learning methods i...

Convolutional neural network on three orthogonal planes for dynamic texture classification

Dynamic Textures (DTs) are sequences of images of moving scenes that exhibit certain stationarity properties in time such as smoke, vegetation and fire. The analysis of DT is important for recognition, segmentation, synthesis or retrieval for a range of applications including surveillance, medical imaging and remote sensing. Deep learning methods have shown impressive results and are now the ne...

Learning of Graph Compressed Dictionaries for Sparse Representation Classification

Despite the limited target data available to design face models in video surveillance applications, many faces of non-target individuals may be captured in operational environments, and over multiple cameras, to improve robustness to variations. This paper focuses on Sparse Representation Classification (SRC) techniques that are suitable for the design of still-to-video FR systems based on unde...
