基带形成与频域均衡研究在matlab中的实现(Baseband form and The Research Of Frequency domain equalization)

一种基于红外图像分层处理及动态压缩的 DDE 算法。该算法先将原始14bits 红外图像数据信息中的大动态低频背景和小动态高频细节进行分离提取，并分别对提取的细节层和背景层进行相应的灰度增强和灰度抑制处理，再调整和压缩各图层的动态范围并最终合成 8bits图 像。实验结果表明，该算法能较好地保留并突出原始红外图像中的边缘和细节信息，达到了预期设计的目标。 (put forward a DDE algorithm based on hierarchical processing and dynamic compression of infrared image． At first，this algorithm dissociates the background ( with wide dynamic and low frequency) and the detail ( with narrow dynamic and high frequency) in the data information ( 14 bits) of original infrared image，and pick up them respectively． Then，it enhances the gray of details layer and restrains the gray of background layer，and readjusts and compresses dynamic range of each layer． Finally，it composites output image ( 8 bits) ． The experimental results show that the proposed algorithm can retain detail information and edges in original infrared image and carry the purpose of design． )

说明：  在Matlab中模拟“落体偏东”想象。物理上，非惯性系下相对运动会产生科里奥利力，正是在科氏力下，地球上的运动物体才会产生偏转。(Simulated in Matlab, &quot off the body towards the east&quot Imagine. Physically, non-inertial Coriolis force generated in the relatively Games, is in the Coriolis force, the earth will produce deflection of moving objects.)

matlab编程时不采用工具箱内的内部函数specgram，按照计算过程直接编写仿真程序(matlab stft)

果蝇优化算法优化灰色神经网络。对不起各位，打包的时候忘记把数据打包进去了。这数据是个25*3的矩阵。前两列数据为{0,1}之间，同一排，若前两个数有一位小于0.5，则第三位为1.否则为0.如此组合25组数据。(FOA gray neural network optimization.)
