WebbOther methods of blurring. The Gaussian blur is a way to apply a low-pass filter in skimage. It is often used to remove Gaussian (i. e., random) noise from the image. For other kinds of noise, e.g. “salt and pepper”, a median filter is typically used. See the skimage.filters documentation for a list of available filters.

Webb25 jan. 2024 · One way to get rid of the noise on the image, is by applying Gaussian blur to smooth it. To do so, image convolution technique is applied with a Gaussian Kernel (3x3, 5x5, 7x7 etc…). The kernel size depends on the expected blurring effect. Basically, the smallest the kernel, the less visible is the blur. Webb13. Finding contours We use a marching squares method to find constant valued contours in an image.
