采用图像感知哈希的TLD改进算法
TLD KCF 量子遗传算法 感知哈希特征
2019/4/17
为了提高长时间视觉目标跟踪的鲁棒性，提出了一种基于图像感知哈希的TLD改进算法。在改进算法中，跟踪模块使用尺度自适应的KCF跟踪器，检测模块对每个检测窗口提取感知哈希特征，并引入量子遗传算法作为搜索策略加快检测速度。对文中算法在OTB2013的50组视频序列上进行了测试，实验结果表明：其跟踪精度与成功率分别达到了0.784和0.568，较TLD算法分别提高了18.7%和14.2%。并且在处理光照变...
针对高耸结构环形TLD的多目标优化设计开展研究。首先,建立了高耸结构环形TLD控制的动力学模型,并编制了其求解程序。随后,提出了采用Sigmoid函数作为独立满意度函数,并通过线性加权建立了复合满意度函数。进而,基于遗传算法(Genetic Algorithm, GA),选取环形TLD的几何参数作为设计变量,结构响应和阻尼器行程的复合满意度作为优化目标,建立了高耸结构环形TLD控制的满意优化设计方...
