• Abstract: 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.

  Current models, which learn from image-text pairs, inherently struggle with counting. We propose optimizing the generated image based on a counting loss derived from a counting model that aggregates an object's potential. We evaluate the generation of various objects and show significant improvements in accuracy.

  Object detection is one of the most important and fundamental aspects of computer vision tasks. To obtain training data for object detection model efficiently, many datasets opt to obtain their unannotated data in video format. Annotating every frame from a video is costly and inefficient since many frames contain very similar information for the model to learn from. In this paper, we proposed a novel active learning algorithm for object detection models to tackle this problem.

  We propose attentional prototype inference (API), a probabilistic latent variable framework for few-shot segmentation. We define a global latent variable to represent the prototype of each object category, which we model as a probabilistic distribution. We conduct extensive experiments on four benchmarks, where our proposal obtains at least competitive and often better performance than state-of-the-art prototype-based methods.
