StackDRL: Stacked Deep Reinforcement Learning for Fine-grained Visual Categorization

Xiangteng He, Yuxin Peng, Junjie Zhao
2018 Proceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence  
Fine-grained visual categorization (FGVC) is the discrimination of similar subcategories, whose main challenge is to localize the quite subtle visual distinctions between similar subcategories.  ...  Semantic reward function drives StackDRL to fully learn the discriminative and conceptual visual information, via jointly combining the attention-based reward and category-based reward.  ...  But the CNN, which is used to extract the attention map for each image, while is not fine-tuned on the specific fine-grained visual categorization dataset.  ...

Coarse Blobs or Fine Edges? Evidence That Information Diagnosticity Changes the Perception of Complex Visual Stimuli

A Oliva
1997 Cognitive Psychology  
Experiment 1 tested whether coarse and fine spatial scales were both available at the onset of scene categorization.  ...  Efficient categorizations of complex visual stimuli require effective encodings of their distinctive properties.  ...  Secondly, the animations simultaneously presented a coarse-to-fine and a fine-to-coarse information sequence to the visual system (coarse-to-fine in LSF, and fine-to-coarse in HSF).  ...
