Description: 基于离散分数布朗随机场模型的水下图像目标检测方法。该方法根据分形理论和水下图像的特点，以图像中每
个像素点为中心取窗口，计算在该窗口内的分形维数均值，将该均值作为中心像素的分形特征，然后根据分形维
数分布图确定分割阈值，从而实现对水下图像分割，并且通过将目标表面不同尺度下的灰度差分平均值进行归一
化处理，减少了用于表示不同尺度下的平均绝对值灰度差分的数据，从而提高算法检测效率(Underwater target detection method based on discrete fractional Brown random field model. According to the fractal theory and the characteristics of underwater images, the method takes every image in the image.
A pixel is taken as the center to take the window, and the mean value of the fractal dimension in the window is calculated. The mean value is taken as the fractal characteristic of the central pixel, and then according to the fractal dimension.
The number distribution map determines the segmentation threshold, so as to realize underwater image segmentation, and normalizing the average value of the gray scale difference under different scales of the target surface.
Chemical processing reduces the mean absolute value of the gray scale difference data at different scales, thus improving the detection efficiency of the algorithm.)

Description: 建立水声信道的射线模型在工程应用上有重要的意义。射线声学是把声波的
传播看作是一束无数条垂直于等相位面的射线的传播，每一条射线与等相位面相
垂直，称为声线。声线途经的距离代表波传播的路程，声线经历的时问为波传播
的时间。声线束所携带的能量即为波传播的声能量。与几何光学相似，射线声学
的描述方法给人直观的感觉，在一定的条件下，射线声学的数学运算也比较简捷，
由射线理论给出的声线图可以给声场以直观、形象的理解。
本模型可以准确的衡量声波在海洋中传播路径(Establishing ray model of underwater acoustic channel is of great significance in engineering application. X-ray acoustics refers to sound waves.
Propagation is regarded as the propagation of a bunch of innumerable rays perpendicular to the isophase plane, each ray being in phase with the isophase plane.
Vertical, called sound line. The distance through which the sound line Travels represents the distance of the wave propagation, and the time that the sound line experiences is the wave propagation.
The time. The energy carried by the sound beam is the sound energy of wave propagation. Like geometric optics, ray acoustics
The descriptive method gives people an intuitive feeling. Under certain conditions, the mathematical operation of ray acoustics is relatively simple.
The sonogram given by ray theory can give an intuitive and visual understanding of the sound field.Accurate measurement of sound wave propagation in the ocean)
