Online Data Curation for Object Detection via Marginal Contributions to Dataset-level Average Precision

CVPR 2026

High-quality data has become a primary driver of progress under scale laws, with curated datasets often outperforming much larger unfiltered ones at lower cost. Online data curation extends this idea by dynamically selecting training samples based on the model's evolving state. While effective in cl

HuPerFlow: A Comprehensive Benchmark for Human vs. Machine Motion Estimation Comparison

CVPR 2025highlight

As AI models are increasingly integrated into applications involving human interaction, understanding the alignment between human perception and machine vision has become essential. One example is the estimation of visual motion (optical flow) in dynamic applications such as driving assistance. Whil…

Modeling Human Visual Motion Processing with Trainable Motion Energy Sensing and a Self-attention Network

NeurIPS 2023poster

Visual motion processing is essential for humans to perceive and interact with dynamic environments. Despite extensive research in cognitive neuroscience, image-computable models that can extract informative motion flow from natural scenes in a manner consistent with human visual processing have yet…

Deep Neural Networks with Flexible Complexity While Training Based on Neural Ordinary Differential Equations

ICASSP 2021accepted

Most structures of deep neural networks (DNN) are with a fixed complexity of both computational cost (parameters and FLOPs) and the expressiveness. In this work, we experimentally investigate the effectiveness of using neural ordinary differential equations (NODEs) as a component to provide further…

HFGCNET: High-Frequency Graph Reasoning for Finer Semantic Image Segmentation

ICASSP 2021accepted

Semantic segmentation is a fundamental task in computer vision and image processing. Although existing methods based on the fully convolutional network (FCN) have greatly improved the accuracy, it still does not show satisfactory results on tiny objects and boundary regions. One of the problems is t…
