Object Counting
26 papers with code • 6 benchmarks • 15 datasets
The goal of Object Counting task is to count the number of object instances in a single image or video sequence. It has many real-world applications such as traffic flow monitoring, crowdedness estimation, and product counting.

CVPR 2016
A single neural network predicts bounding boxes and class probabilities directly from full images in one evaluation.
Where are the Blobs: Counting by Localization with Point Supervision
However, we propose a detection-based method that does not need to estimate the size and shape of the objects and that outperforms regression-based methods.
From Open Set to Closed Set: Supervised Spatial Divide-and-Conquer for Object Counting

Visual counting, a task that aims to estimate the number of objects from an image/video, is an open-set problem by nature, i. e., the number of population can vary in [0, inf) in theory.
Synbols: Probing Learning Algorithms with Synthetic Datasets

NeurIPS 2020
Progress in the field of machine learning has been fueled by the introduction of benchmark datasets pushing the limits of existing algorithms.
Towards perspective-free object counting with deep learning
Essentially, the CCNN is formulated as a regression model where the network learns how to map the appearance of the image patches to their corresponding object density maps.
Improving Object Counting with Heatmap Regulation

CVPR 2019
Moreover, our approach improves state-of-the-art image-level supervised instance segmentation with a relative gain of 17. 8% in terms of average best overlap, on the PASCAL VOC 2012 dataset.

Through our analysis, we expect to make reasonable inference and prediction for the future development of crowd counting, and meanwhile, it can also provide feasible solutions for the problem of object counting in other fields.
Unsupervised Domain Adaptation For Plant Organ Counting
p2irc/UDA4POC
•
•
Supervised learning is often used to count objects in images, but for counting small, densely located objects, the required image annotations are burdensome to collect.
