论文摘要
对象检测是一项基本的计算机视觉任务，可以在给定图像中loccal和对象进行分类。大多数最先进的检测方法都利用固定数量的提案作为对象候选物的中间表示，在推理过程中无法适应不同的计算约束。在本文中，我们提出了一种简单而有效的方法，该方法通过生成动态提案以进行对象检测来适应不同的计算资源。我们首先设计一个模块来制作一个基于查询的模型，以便能够使用不同数量的建议进行推断。此外，我们将其扩展到动态模型，以根据输入图像选择建议数量，从而大大降低了计算成本。我们的方法在广泛的检测模型中实现了显着的加速，包括两阶段和基于查询的模型，同时获得相似甚至更好的准确性。
Object detection is a basic computer vision task to loccalize and categorize objects in a given image. Most state-of-the-art detection methods utilize a fixed number of proposals as an intermediate representation of object candidates, which is unable to adapt to different computational constraints during inference. In this paper, we propose a simple yet effective method which is adaptive to different computational resources by generating dynamic proposals for object detection. We first design a module to make a single query-based model to be able to inference with different numbers of proposals. Further, we extend it to a dynamic model to choose the number of proposals according to the input image, greatly reducing computational costs. Our method achieves significant speed-up across a wide range of detection models including two-stage and query-based models while obtaining similar or even better accuracy.
