image smoothing

Image smoothing is a fundamental image processing technique in computer vision aimed at reducing noise and details in an image through the use of filters to simplify subsequent processing tasks. Its primary goal is to preserve the main structural features of the image while eliminating high-frequency noise, thereby improving image quality and robustness. Image smoothing plays a crucial role in applications such as edge detection, feature extraction, and image segmentation, significantly enhancing the performance and stability of algorithms.
