PaddlePaddle has built a large-scale official model zoo with a large number of algorithms which have been practiced and polished for a long time in industry. PaddleCV, mainly focusing on the computer vision(CV) areas, provides multiple end-to-end development kits, including image classification, object detection, image segmentation, OCR and other scenarios, to meet the requirements of enterprises for low-cost development and rapid integration. In the demonstration applications, it is shown how to use ultra lightweight PP-OCR and PP-YOLOv2 systems to solve the OCR and object detection tasks among server, mobile, embedded and IoT devices, respectively.
