高通滤波 [电子] high-pass filtering
- 本文将高通滤波和数学形态学图像处理算法相结合,提出一种新的预处理方法。
A new image preprocessing method based on high-pass filter and morphology is presented. - 这种相关器与一般的二元联合变换相关器的差别在于联合功率谱作二元处理之前先进行高通滤波。
The difference between the proposed correlator and BJTC is that joint power spectrum is processed by using high pass filtering before applying binarization. - 采用这种技术,可以实现数字图像卷积运算,因此可以完成图像的低通滤波、高通滤波、强化边缘等处理。
With this technique, the digital image convolution can be realized, therefore, the image low-pass filtering, image high-pass filtering, edge-enhancing could be realized.
