Image Filtering

Image filtering is a technique used to remove unwanted noise from an image while preserving important features. It has a variety of applications in the fields of computer vision, medical imaging, and remote sensing. Image filtering can also be used to improve the visual quality of images by enhancing contrast and brightness, or by removing unwanted artifacts and distortions.

What Is Image Filtering?

The goal of image filtering is to enhance an image by removing or modifying its features. This can be done using various linear and non-linear filters that process the image pixel by pixel. Filters are typically designed to achieve specific objectives, such as removing noise, sharpening edges, or reducing blur.

Linear filters are typically used for basic image processing tasks, such as smoothing and sharpening. Non-linear filters, on the other hand, are often used for more complex tasks, such as noise removal and edge detection.

Why Learn Image Filtering?

Image filtering is an important technique that can be applied in various fields. By understanding and applying image filtering, you can improve the visual quality of your images and gain valuable insights from them. With online courses available, learning image filtering has become more accessible, offering learners the flexibility to study at their own pace and convenience.
