Event-based Tiny Object Detection: A Benchmark Dataset and Baseline

ICCV 2025poster

Small object detection (SOD) in anti-UAV task is a challenging problem due to the small size of UAVs and complex backgrounds. Traditional frame-based cameras struggle to detect small objects in complex environments due to their low frame rates, limited dynamic range, and data redundancy. Event camer…

Monte Carlo Linear Clustering with Single-Point Supervision is Enough for Infrared Small Target Detection

ICCV 2023poster

Single-frame infrared small target (SIRST) detection aims at separating small targets from clutter backgrounds on infrared images. Recently, deep learning based methods have achieved promising performance on SIRST detection, but at the cost of a large amount of training data with expensive pixel-lev…

Learnable Lookup Table for Neural Network Quantization

CVPR 2022poster

Neural network quantization aims at reducing bit-widths of weights and activations for memory and computational efficiency. Since a linear quantizer (i.e., round(*) function) cannot well fit the bell-shaped distributions of weights and activations, many existing methods use pre-defined functions (e.…

Occlusion-Aware Cost Constructor for Light Field Depth Estimation

CVPR 2022poster

Matching cost construction is a key step in light field (LF) depth estimation, but was rarely studied in the deep learning era. Recent deep learning-based LF depth estimation methods construct matching cost by sequentially shifting each sub-aperture image (SAI) with a series of predefined offsets, w…

Exploring Sparsity in Image Super-Resolution for Efficient Inference

CVPR 2021poster

Current CNN-based super-resolution (SR) methods process all locations equally with computational resources being uniformly assigned in space. However, since missing details in low-resolution (LR) images mainly exist in regions of edges and textures, less computational resources are required for thos…

Learning a Single Network for Scale-Arbitrary Super-Resolution

ICCV 2021poster

Recently, the performance of single image super-resolution (SR) has been significantly improved with powerful networks. However, these networks are developed for image SR with specific integer scale factors (e.g., x2/3/4), and cannot handle non-integer and asymmetric SR. In this paper, we propose to…

Unsupervised Degradation Representation Learning for Blind Super-Resolution

CVPR 2021poster

Most existing CNN-based super-resolution (SR) methods are developed based on an assumption that the degradation is fixed and known (e.g., bicubic downsampling). However, these methods suffer a severe performance drop when the real degradation is different from their assumption. To handle various unk…

Spatial-Angular Interaction for Light Field Image Super-Resolution

ECCV 2020poster

Light field (LF) cameras record both intensity and directions of light rays, and capture scenes from a number of viewpoints. Both information within each perspective (i.e., spatial information) and among different perspectives (i.e., angular information) is beneficial to image super-resolution (SR).…

Learning Parallax Attention for Stereo Image Super-Resolution

CVPR 2019poster

Stereo image pairs can be used to improve the performance of super-resolution (SR) since additional information is provided from a second viewpoint. However, it is challenging to incorporate this information for SR since disparities between stereo images vary significantly. In this paper, we propose…
