Multiple Camera Fusion Techniques

How does pixel-level fusion differ from feature-level fusion in multiple camera fusion techniques?

Pixel-level fusion in multiple camera fusion techniques involves combining individual pixels from different cameras to create a single, high-resolution image. This differs from feature-level fusion, which combines extracted features or characteristics from each camera's image. Pixel-level fusion focuses on the raw pixel data, while feature-level fusion emphasizes specific elements like edges, textures, or colors. Both techniques have their advantages and are used based on the specific requirements of the fusion system.
