Hierarchical Deep Click Feature Prediction for Fine-Grained Image Recognition
IEEE Transactions on Pattern Analysis and Machine Intelligence(2022)
摘要
The click feature of an image, defined as the user click frequency vector of the image on a predefined word vocabulary, is known to effectively reduce the semantic gap for fine-grained image recognition. Unfortunately, user click frequency data are usually absent in practice. It remains challenging to predict the click feature from the visual feature, because the user click frequency vector of an ...
