Bounding box regression is a technique used in computer vision and object detection tasks. It involves adjusting the coordinates of bounding boxes to better fit the objects they are meant to detect, improving the accuracy of object localization. This process typically occurs after an initial set of candidate regions has been proposed by another mechanism such as selective search or region proposal networks (RPNs). The regression step fine-tunes these proposals based on ground truth information about the actual positions and sizes of objects in the image.
Bounding box regression is a critical component in many state-of-the-art object detection frameworks, including Faster R-CNN, YOLO, and SSD. These models often use loss functions specifically designed for bounding box regression to optimize the adjustment process. Commonly used losses include Smooth L1 Loss (also known as Huber loss), which helps reduce the impact of outliers on training.
In summary, bounding box regression plays a vital role in refining object location predictions within images, thereby enhancing overall detection performance.
