Image Saliency Detection: Algorithms and Implementation Approaches

With the rapid development of the internet and explosive growth of digital media data, we now possess information resources unparalleled in any previous era. Compared to textual information, digital images are more intuitive, realistic, and visually engaging. To efficiently extract valuable information from these visual data, computational vision technologies have become indispensable. Visual Saliency originates from human vision research, describing how certain elements in a scene attract visual attention. Human visual perception operates through two stages - a fast, bottom-up, saliency-driven task-agnostic phase and a slower, top-down, consciousness-driven task-oriented phase. This content explores computational methods for image saliency detection with technical implementations.
