Bottom-up and top-down attention for image
WebThis is the natural basis for attention to be considered. Within our approach, the bottom-up mechanism (based on Faster R-CNN) proposes image regions, each with an associated … WebThis is why recent deep learning approaches mostly include some “attention” mechanism (sometimes even more than one) to help focusing on relevant image features. In this post, we demonstrate a formulation of image captioning as an encoder-decoder problem, enhanced by spatial attention over image grid cells.

WebMar 30, 2007 · Volitional shifts of attention are thought to depend on “top-down” signals derived from knowledge about the current task (e.g., finding your lost keys), whereas the automatic “bottom-up” capture of attention is driven by properties inherent in stimuli—that is, by salience (e.g., a flashing fire alarm) (1–3).Imaging and neurophysiological studies …
WebDec 20, 2013 · Attention can be categorized into two distinct functions: bottom-up attention, referring to attentional guidance purely by externally driven factors to stimuli that are salient because of their inherent properties relative to the background; and top-down attention, referring to internal guidance of attention based on prior knowledge, willful ...
