WebSmoothing, also known as blurring, is one of the most commonly used operation in Image Processing. The most common use of the smoothing operation is to reduce noise in the … WebOpenCV provides mainly four types of blurring techniques. 1. Averaging This is done by convolving image with a normalized box filter. It simply takes the average of all the pixels under kernel area and replace the central element. This is done by the function cv2.blur () or cv2.boxFilter (). Check the docs for more details about the kernel.

Web22 Jan 2024 · Step 5.1 : Fix border artifacts. When we stabilize a video, we may see some black boundary artifacts. This is expected because to stabilize the video, a frame may have to shrink in size. We can mitigate the problem by scaling the video about its center by a small amount (e.g. 4%).

Web21 Mar 2015 · Most smoothing filters (e.g. a Gaussian or a Box filter) in image processing and computer vision have a parameter called sigma_s (for Sigma_Spatial) that determines the amount of smoothing.
