visual artifacts

Visual artifacts are unwanted distortions or anomalies that appear in images or videos due to digital processing limitations. They can manifest as strange colors, blocky areas, blurring, or lines that shouldn't be there. These artifacts often occur during compression to reduce file size, when hardware or software struggles with rendering, or due to signal interference. Essentially, they are visual glitches that disrupt the natural appearance of the image, making it look less clear or realistic. Understanding them helps in diagnosing issues with digital media quality and enhances efforts to improve image and video processing techniques.
