Description: High-frequency noise refers to unwanted signals that appear in digital images, affecting their quality and clarity. This type of noise can manifest as random patterns or distortions that obscure important details, making it difficult to view and analyze the image. Generally, high-frequency noise originates from the image capture process, whether due to limitations of the camera sensor, inadequate lighting conditions, or electronic interference. It often appears in high-contrast areas, where fine details are more susceptible to distortion. The presence of high-frequency noise can be particularly problematic in applications where precision and clarity are crucial, such as in various fields including medicine, astronomy, and professional photography. To mitigate its effects, various image processing techniques are employed, such as noise reduction and filtering, which aim to preserve important details while eliminating unwanted signals. In summary, high-frequency noise is a phenomenon that can compromise image quality, and proper handling is essential for achieving optimal visual results.
