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]) 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. is there a market for film cameras
