OpenCV 3 image and video processing with Python OpenCV 3 with Python Image - OpenCV BGR : Matplotlib RGB Basic image operations - pixel access iPython - Signal Processing with NumPy Signal Processing with NumPy I - FFT and DFT for sine, square waves, unitpulse, and random signal Signal Processing with NumPy II - Image Fourier Transform : FFT & DFT En OpenCV GaussianBlur es una operación o función que permite aplicar un filtro de desenfoque a una imagen. Este tipo de filtros es muy útil para quitar ruido de alta frecuencia (pixeles cambiando muy rápido) para una imagen. Por ejemplo, se puede aplicar en el proceso de crear un filtro de color. 前文传送门: 「Python图像处理OpenCV(1):入门」 「Python图像处理OpenCV(2):像素处理与Numpy操作以及Matplotlib显示图像」 「Python图像处理OpenCV(3):图像属性、图像感兴趣ROI区域及通道处理」 「Python图像处理OpenCV(4):图像算数运算以及修改颜色空间」 「Python图像处理OpenCV(5):图像的几何 ...
