SEQUENCES USING ADAPTABLE NEURAL NETWORKS Nikolaos Doulamis and Anastasios Doulamis National Technical University of Athens, Electrical and Computer Engineering Department, 15773, Athens, Greece E-mail: [email protected] Abstract In this paper, an adaptive neural network architecture is proposed for efficient video object segmentation and tracking of stereoscopic sequences. The scheme includes (a) a retraining algorithm for adapting network weights to current conditions, (b) a semantically meaningful object extraction module for creating a retraining set and (c) a decision mechanism, which detects the time instances that a new network retraining is required. The retraining algorithm optimally adapts network weights by exploiting information of the current condition with a minimal deviation of the network weights. Description of the current conditions is provided by a segmentation fusion scheme, which appropriately combines color and depth information.

An efficient fully unsupervised video object segmentation scheme using an adaptive neural-network classifier architecture
In this paper, an unsupervised video object (VO) segmentation and tracking algorithm is proposed based on an adaptable neural-network architecture. The proposed scheme comprises: 1) a VO tracking module and 2) an initial VO estimation module. Object tracking is handled as a classification problem and implemented through an adaptive network classifier, which provides better results compared to c...
متن کاملObject Tracking and Segmentation with a Population of Artificial Neural Networks
We present a study concerning the use of artificial neural networks for object tracking/segmentation in surveillance video sequences. A number of artificial creatures, conceptually, “inhabit” our image sequences. Their task is to explore the images looking for moving objects. Their behaviour is controlled by neural networks which are evolved with an Evolutionary Algorithm (EA). In our system we...

This paper presents a comparison study between the multilayer perceptron (MLP) and radial basis function (RBF) neural networks with supervised learning and back propagation algorithm to track hand gestures. Both networks have two output classes which are hand and face. Skin is detected by a regional based algorithm in the image, and then networks are applied on video sequences frame by frame in...
متن کاملHandling occlusion in object tracking in stereoscopic video sequences
Stereo vision is a part of the field of computer vision that uses two or more cameras to obtain two or more images from which distance information can be obtained by using the triangulation principle [1]. We can obtain three-dimensional information of static scenes by using this technique. On the other hand, we can use optical flow algorithms for object tracking in two dimensional video sequenc...
متن کاملUsing a Novel Concept of Potential Pixel Energy for Object Tracking
Abstract In this paper, we propose a new method for kernel based object tracking which tracks the complete non rigid object. Definition the union image blob and mapping it to a new representation which we named as potential pixels matrix are the main part of tracking algorithm. The union image blob is constructed by expanding the previous object region based on the histogram feature. The pote...
