    Abstract: Embodiments of the subject matter described herein relate to object detection based on neural network. In some implementations, a candidate region in an image, a first score and a plurality of positions associated with the candidate region are determined from a feature map of the image, and the first score indicates a probability that the candidate region corresponds to a particular portion of an object. A plurality of second scores are determined from the feature map and indicate probabilities that the plurality of positions correspond to a plurality of parts of the object, respectively. A final score of the candidate region is determined based on the first score and the plurality of second scores, to identify the particular portion of the object in the image.

  • Publication number: 20200334867
    Abstract: In accordance with implementations of the subject matter described herein, there is provided a solution for face synthesis. In this solution, a first image about a face of a first user and a second image about a face of a second user are obtained. A first feature characterizing an identity of the first user is extracted from the first image, and a second feature characterizing a plurality of attributes of the second image is extracted from the second image, where the plurality of attributes do not include the identity of the second user. Then, a third image about a face of the first user is generated based on the first and second features, the third image reflecting the identity of the first user and the plurality of attributes of the second image.
