About PASCAL VOC Datasets

Object detection is one of three basic tasks in computer vision, and it's also a challenging problem in the field of computer vision. Pascal VOC Challenge is one of the three most important computer vision challenges in the world. The datasets have high quality annotations, complex scenarios and diverse targets; and therefore, it is a prime choice for fast testing algorithms. Pascal VOC does not have big datasets, but it has rich scenes, therefore it tests for the design and innovation ability of AI.

Pascal VOC is the main venue for AI companies to compete, and competition is fierce. It attracts nearly 100 professional teams from across the world, including Google, Microsoft, Carnegie Mellon, Tsinghua University, Alibaba, Ping An Technology, Sogou and Yi+.

Pascal VOC datasets have 20 classes, including humans, animals, vehicles and indoor objects. AInnovation's computer vision team participated in the competion4 subtask. Across all twenty classes of the competition, AInnoDetection ranked first in ten classes, and ranked first overall by total score.

The AInnoDetection Algorithm

The AInnoDetection model proposed by the team is based on the classic two-stage detection pipeline, with data augmentation including pasting small objects and mix-up methods to enhance the performance when detecting small and obscured objects, respectively. Also, the data augmentation makes the network more robust.

The famous two-stage detection network was implemented, the backbone of ResNext152 for multi-level feature extraction, neck of 6-level FPN structure and head of 3x cascade RCNN, each of them had two subnets, one for classification with focal loss and another for bounding box regression with smooth L1 loss. Meanwhile, no matter training or inference, multi-scale images are taken, forcing the network to focus and learn how to recognize objects of different scales.
