BEIJING, May 30, 2019 /PRNewswire/ -- Recently, WIDER FACE, one of the world's authoritative public evaluation dataset for face detection, released its latest rankings. "AInnoFace", the algorithm developed by AInnovation surpassed the performance of many well-known AI enterprises and university laboratories, including Baidu, Tencent, JD.com, DiDi, Carnegie Mellon, University of Chinese Academy of Sciences, among others. AInnoFace ranked first overall across all three subsets "Easy", "Medium" and "Hard" of the WIDER FACE Challenge under six evaluation criteria (ranking first in five criteria and second in only one).
AInnovation Ranks First in WIDER FACE
Taking the "World's Largest Selfie" for example, the AInnoFace algorithm detected 918 faces with a high degree of detection accuracy. By comparison, Baidu's PyramidBox algorithm detected only 880 faces in the photo.
AInnovation Found 918 Faces
The AInnoFace algorithm of AInnovation is developed from the well-known RetinaNet single-stage detector, and adopts a IoU regression loss for Bounding-Box regression to improve location detection accuracy, implements a Selective Refinement Network for higher Recall Rates and lower False Positive Rates, utilizes an augmented strategy of rich data variety for more robust final detection model, leverages Max-out Label to make more accurate classification predictions, and uses an improved multi-scale detection strategy to detect better faces at different scales. Through the above mentioned improvements, the AInnoFace algorithm can maintain outstanding detection performance even at the extremes, if faces are small, dimmed or covered. Altogether, the AInnoFace algorithm is able to effectively improve the recall rate and accuracy of face detection in complex scenes, and addresses the technical problems of face detection in public scenarios.
About WIDER FACE
Face detection is an increasingly popular and challenging problem in the field of Computer Vision and one of the most important business scenarios for AI algorithms. In order to improve the performance of their AI algorithms and showcase their technical capabilities, many AI companies choose public datasets to validate their algorithms. Among the available face detection datasets, WIDER FACE is one of the largest and most challenging dataset. This dataset contains 32,203 images and 393,703 face tags, in which 40% are training images, 10% are validation images, and 50% are testing images. The data in each set can be classified as "Easy", "Medium" and "Hard" based on the difficulty of face detection.
Pictures in WIDER FACE are extremely difficult to recognize, and approach those in real scenarios. The dataset contains pictures with a variety of influencing factors, such as dramatic variation in face size, various photographic angles, changes in face pose, different degrees of occlusion and changes in facial expression, various types of light pollution, brightness considerations, and various makeup styles. Therefore, WIDER FACE is famous for its challenging datasets in the field, and attracts a large number of international technology giants, institutions and universities (including Carnegie Mellon and other established universities around the world, as well as famous AI companies such as Baidu, Tencent, JD.com, DiDi, IBM, and others).
