WebJan 3, 2024 · Gaussian Blurring is the smoothing technique that uses a low pass filter whose weights are derived from a Gaussian function. In fact, this is the most widely used low pass filter in CV (computer vision) applications. Different properties of the gaussian filter make the algorithm more efficient. Syntax: cv.getGaussianKernel (ksize, sigma [, ktype]) WebMar 26, 2024 · The shape of a Gaussian filter (on the left) and a Bilateral filter (on the right) Gaussian blurring is nothing but using the kernel whose values have a Gaussian distribution.The values are generated by a Gaussian function so it requires a sigma value for its parameter.

WebThe GaussianBlur function applies this 1D kernel along each image dimension in turn. The separability property means that this process yields exactly the same result as applying a 2D convolution (or 3D in case of a 3D image). But the amount of work is strongly reduced.

Image and video processing: OpenCV provides a wide range of functions for image and video processing, such as image filtering, image transformation, and feature detection. For example, the following code applies a Gaussian blur to an image:

WebThe GaussianBlur () function requires four input arguments: The first argument, src, specifies the source image that you want to filter. The second argument is ksize, which defines the size of the Gaussian kernel. Here, we are using a 5×5 kernel. The final two arguments are sigmaX and sigmaY, which are both set to 0.
