# opencv-python# cv2.getGaussianKernel(r, sigma)返回一个shape为(r, 1)的np.ndarray, fspecial里核的size的参数是先行后列, 因此:H = np.multiply(cv2.getGaussianKernel(r, sigma), (cv2.getGaussianKernel(c, sigma)).T)# H.shape == (r, c)...

其中:x^\prime表示当前像素位置,G^\prime (x^\prime )是之前提到的三维高斯函数G (x)对应视角的二维高斯,\alpha_i为不透明度,\sigma_i为x位置对应的不透明度,N为覆盖当前像素点三维高斯数量; 可以理解为不透明度\alpha_i为光线透过的概率,通过二维高斯可以得到当前像素点的不透明度,和当前三维高斯颜色相乘可以...
This project implements a Gaussian Blur filter using pure NumPy, without relying on SciPy or OpenCV. The script converts an image to grayscale, applies a manually defined Gaussian kernel, and performs convolution using NumPy operations. python numpy gaussian-blur Updated Feb 23, 2025 Python Sp...
A Gaussian smoothing filter is applied here to the contrast-enhanced image using the Gaussian function. Fig. 3.3D shows the output (Igs) after applying the Gaussian smoothing. 2D Gaussian function is mentioned in Eq. (3.2). The distance from the origin is x and y along the horizontal and ...
In this OpenCV tutorial, we will learn how to apply Gaussian filter for image smoothing or blurring using OpenCV Python with cv2.GaussianBlur() function.
