How to Detect Small Objects: A Guide
Blog post from Roboflow
Detecting small objects in computer vision presents significant challenges due to their size relative to the overall image, which complicates the task for object detection models. The article explores strategies to improve performance in small object detection, focusing on two optimization stages: inference and preprocessing. Techniques such as increasing image resolution, tiling images, and data augmentation are suggested to enhance model accuracy. The use of tools like Roboflow's InferenceSlicer, which divides images into smaller segments for analysis, is highlighted for its effectiveness in improving inference precision. Additionally, the text discusses the importance of optimizing model parameters such as input resolution and anchor boxes, and managing datasets to filter extraneous classes. Overall, the guide provides a comprehensive overview of practices that can help improve the detection of small objects in images, emphasizing the need for tailored approaches depending on specific use cases.
