High-speed face search by threshold value determination method using neural networksIn order to recognize automatically faces with unknown position and size in an image, the processing which searches faces area is required before face recognition. By development of such technologies it is important to...
First we show that, in general, neural response in both spontaneous and nonspontaneous firing give rise to generalized functions of the Dirac type. For spontaneous unstimulated firing we solve a homogeneous eigenvalue equation and obtain a family of gamma type functions. Finite linear combinations ...

In this model the threshold voltage is increased by a fixed amount β/τa when the neuron fires and then decays exponentially back to a baseline value bj0 with a time constant τa (see Fig. 1a). Fig. 1: Qualitative description of neuron models and network architecture for LSNN tasks. a...
PURPOSE:To give a proper threshold value in response to a picture signal by selecting any of a simple binarizing threshold value, an intermediate area processing threshold value and a threshold value of a threshold matrix based on a mode designation signal. CONSTITUTION:A simple binarization thresho...
1b). Similar to other dynamical cascade models39,40, contagion initially evolves at a linear rate until the density ρ(t) of infected nodes reaches a critical value, triggering a rapid cascade of infection that spreads through the whole network (sample scenarios in Fig. 1c,d). Thus, to ...
In this work, based on the Pulse Shape Discrimination (PSD) and Back-Propagation (BP)artificial neural networks, a neutron-gamma discrimination method is developed to broaden the lower limitof energy threshold with the hidden layer of 20 neurons." 展开 关键词: Lanzhou People’s Republic of ...
1) the threshold value of warning 预警阈值 1. According to the results of the experiments, put forward warning index andthe threshold value of warningof soil enzyme for heavy metals Cu~(2+), Cr~(3+), Pb~(2+) pollution of Shandong brown soil. ...
A threshold algorithm is a method used in image segmentation that involves selecting a critical value to distinguish objects from the background based on pixel intensity levels. AI generated definition based on: Computers and Electronics in Agriculture, 2014 ...
The proposed approach uses an early blacklist strategy to alleviate the attack and restore the network performance. The node's behaviour is analysed to identify normal and suspicious behavior. In addition, the DAO prefix is used to control the DAO counter value. The findings reveal acceptable ...
