In this paper,we propose a method of target detection in IR(Infrared) images. In order to effectively detect target regions,the spatial information of the target is first considered by analyzing the pixel distributions of horizontal and vertical projections. Through analyzing the distributions,the target region is detected by eliminating various backgrounds such as noises and clutters. In order to effectively detect the target region,a novel thresholding method is proposed. As experimental results,the proposed method has achieved better performance than the existing methods.

Dynamic neural networks comprise a class of neural networks that is particularly suitable for predicting variables like travel time, but has not been adequately investigated. This study compares the travel time prediction performance of three dynamic neural network topologies with different memory settings. The results show that the time-delay neural networks out-performed the other two topologies. This topology also performed slightly better than the multilayer perceptron neural networks.
