Abstract:

Fine-grained classification aims to classify the images (cars, dogs, flowers, birds, etc.), belonging to the same basic category, into a more detailed subcategory. It is a very popular research topic in the fields of Computer Vision and Pattern Recognition in recent years and is widely used in various fields (such as Species Classification of Ecology, Commodity Classification of Automatic Sorting, Garbage Classification of Environmental Protection, etc.). Because the differences between subcategories are subtle and usually exist in the local areas, how to efficiently select highly differentiated local areas and how to optimize their characteristics is the focus of the current research. This report will introduce our exploration in these two aspects. Firstly, I will introduce two relationship-guided differential region learning methods from the perspective of local regional correlation mining. Secondly, a characterization optimization method based on the discriminant prior network model and autoregressive model is introduced. Finally, the research trends of fine-grained image classification are discussed.
