Selective Feature Connection Mechanism: Concatenating Multi-layer CNN Features with a Feature Selector

Chen Du, Chunheng Wang, Yanna Wang +2

Different layers of deep convolutional neural networks(CNNs) can encode different-level information. High-layer features always contain more semantic information, and low-layer fea…

Unsupervised Semantic-based Aggregation of Deep Convolutional Features

Jian Xu, Chunheng Wang, Chengzuo Qi +2

In this paper, we propose a simple but effective semantic-based aggregation (SBA) method. The proposed SBA utilizes the discriminative filters of deep convolutional layers as seman…

Unsupervised Part-based Weighting Aggregation of Deep Convolutional Features for Image Retrieval

Jian Xu, Cunzhao Shi, Chengzuo Qi +2

In this paper, we propose a simple but effective semantic part-based weighting aggregation (PWA) for image retrieval. The proposed PWA utilizes the discriminative filters of deep c…
