Aiming at tlie problems of large date in color image fusion of tlie thermal fault location of electrical equipment,researches and inductions were made for the color image fusion and compressed sensing theory,a kind of infrared and visible color image fusion algoritlim based on compressed sensing was proposed. Firstly,the infrared thermal image and visible color image date was decomposed into three channels of R,G,B,each channel of the date was represented by wavvlet-basis. Secondly,Gauss random matrix was used to sample the sparse data and get the measured value,the measurement value of the corresponding channel was fused by the weighting factors. Finally,the orthogonal matching pursuit reconstruction algorithm (OMP) was performed to reconstruct the fusion data of each channel,the reconstruction data was restored to the color fused image. The results indicate that the proposed algorithm can achieve fusion with less than 50% of the sample points. The value of AG,PSNR,SF,IE is close to the index of traditional data fusion,which maintaines the information of high temperature area and background area perfectly. [ABSTRACT FROM AUTHOR] 相似文献

在电力系统中谐波检测的实时性和精确度是一个重要部分,目前谐波检测中多以低通滤波器进行滤波,但是由于其要采集大量数据才可以实现稳定输出的固有特性,限制了其实时性和精确度的提高。人工神经网络可以进行滤波分析,但现有神经网络滤波几乎都基于MATLAB仿真,硬件测试的较少。在Linux系统中用C++在Qt软件编程实现三角基函数神经网络滤波,并把文中算法在X86和ARM两个不同芯片下的运行效果与在MATLAB中低通滤波器滤波做对比,发现在实际测试中该算法可以提高精确度,加快响应速度,其次还介绍了算法在基于X86和ARM两个不同芯片下环境配置,编译,实现等技术细节。 相似文献

传统的Struck算法在人脸跟踪系统中,需要手动实现初始化且易受环境影响。文中提出一种基于AdaBoost目标自动检测和改进的Struck人脸自动跟踪算法。从图像中提取人脸的Haar特征,采用AdaBoost算法实现人脸的检测,并自动初始化跟踪器,再依据检测得到的相邻帧目标的相似度判定跟踪目标的有效性,采用Struck算法实现人脸的连续跟踪。实验结果表明,改进的算法有效解决了部分遮挡、尺度变化、光照变化等人脸跟踪难题,且具有较高的鲁棒性与准确性。 相似文献

本文报道射频电视信号对GaAlAs双异质半导体激光的频率调制。使用自研制由两个Farbry-Perot腔组成的高分辨率光谱测量系统,当用射频电视信号调制半导体激光器的电流时,成功地测量到输出激光的调制边带。文中提出一个简单的模型:将半导体激光器看成一个充满介质的F-P腔,介质内部电流受调制时,腔的谐振频率可写成调制电流的函数,进而以此模型说明实验结果。 相似文献
