查询词典 threshold intensity

Image is processed by using median filter and unsharp mask. The infrared image intensity surface is fitted by Haralickd discrete orthogonal polynomial basis function,and then the maximum points are detected on the fitted intensity surface by convolving the image with the second order directional derivative operators.

中文摘要：提出一种红外弱小多目标图像检测方法，图像先经过中值滤波、高提升滤波增强处理，再用基于Haralick离散正交多项式曲面拟合图像，拟合曲面的极大值点即目标点，可以利用导出的二阶方向导数算子与图像进行卷积得到。

Integrating the sound intensity vector on the area which surrounds a sound source gets the sound power of this sound source. Since the integral of the sound power of the sound sources which are not enclosed by the area is zero, one could measure the sound power in ordinary environments correctly by measuring sound intensity.

对于一个声源，只要将其包络面上的声强矢量作积分，就可以求出被围声源的声功率，而测量区域之外的干扰噪声得以抵消，因此可以在普通环境下能准确地测定声源声功率。
