The Importance of Blur as an Image Augmentation Technique

WebThe Gaussian filter is a spatial filter that works by convolving the input image with a kernel. This process performs a weighted average of the current pixel’s neighborhoods in a way that distant pixels receive lower weight than these at the center. The result of such low-pass filter is a blurry image with better edges than other uniform ... WebAug 23, 2024 · Using the default means you're using a 3 x 3 kernel and no blurring is applied. However, anything above 3 x 3 will use a Gaussian kernel. Therefore, if you want to use the default Sobel kernel, you would need to apply the blurring yourself. If you vary the size of the Sobel kernel you don't have to perform blurring yourself. WebWhat would Gaussian blur be called? In image processing, a Gaussian blur (also known as Gaussian smoothing) is the result of blurring an image by a Gaussian function (named after mathematician and scientist Carl Friedrich Gauss).
