Recursive Multi-Scale Channel-Spatial Attention for Fine-Grained Image Classification

Attention for Fine-Grained Categorization

This paper presents experiments extending the work of Ba et al. (2014) on recurrent neural models for attention into less constrained visual environments, beginning with fine-grained categorization on the Stanford Dogs data set. In this work we use an RNN of the same structure but substitute a more powerful visual network and perform large-scale pre-training of the visual network outside of the...

Deep Spatial-Semantic Attention for Fine-Grained Sketch-Based Image Retrieval

Here we offer a more detailed description of the proposed model to facilitate re-implementation. A schematic illustration of the network architecture of the proposed model can be found in Fig. 2 of the main paper. It shows that the model is a Siamese triplet network with three branches of identical architectures and shared parameters. In this section, we further describe the detailed network ar...

Hierarchical Metric Learning for Fine Grained Image Classification

This paper deals with the problem of fine-grained image classification and introduces the notion of hierarchical metric learning for the same. It is indeed challenging to categorize fine-grained image classes merely in terms of a single level classifier given the subtle inter-class visual differences. In order to tackle this problem, we propose a two stage framework where i) the image categorie...

Object-centric Sampling for Fine-grained Image Classification

This paper proposes to go beyond the state-of-the-art deep convolutional neural network (CNN) by incorporating the information from object detection, focusing on dealing with fine-grained image classification. Unfortunately, CNN suffers from over-fiting when it is trained on existing finegrained image classification benchmarks, which typically only consist of less than a few tens of thousands t...
