چکیده

Present paper demonstrates on innovative approach for a fundamental problem in computer vision to map real time a pixel in one image to a pixel on another image of the same scene, which is generally called image correspondence problem. It is a novel real time image matching method which combines Rotational Invariant Feature Selection for real time images and optimization capabilities of Hopfield Neural Networks. The most invariant image matching features are extracted from the reference image. Finally, the image matching process is optimized by Hopfield neural networks, where image matching problem is treated as minimization of energy function of the Hopfield neural networks.

Neural Network Performance Analysis for Real Time Hand Gesture Tracking Based on Hu Moment and Hybrid Features

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...

Stereo-correspondence using Gabor logons and neural networks

Stereo-correspondence is the most important issue in stereopsis. Feature extraction and matching are the basic steps involved in the solution of stereocorrespondence problem. This work examines the effectiveness of Gabor Logons as pre-processing technique compared to intensity image. The matching is performed using Hopfield network and Simulated Annealing. Performance of these matching techniqu...

Parallel distributed detection of feature trajectories in multiple discontinuous motion image sequences

Concerns the 3D interpretation of image sequences showing multiple objects in motion. Each object exhibits smooth motion except at certain time instants when a motion discontinuity may occur. The objects are assumed to contain point features which are detected as the images are acquired. Estimating feature trajectories in the first two frames amounts to feature matching. As more images are acqu...

The Neurodynamics of Belief Propagation on Binary Markov Random Fields

We rigorously establish a close relationship between message passing algorithms and models of neurodynamics by showing that the equations of a continuous Hopfield network can be derived from the equations of belief propagation on a binary Markov random field. As Hopfield networks are equipped with a Lyapunov function, convergence is guaranteed. As a consequence, in the limit of many weak connec...
