摘要： A target face tracking method, an apparatus, an electronic device and a storage medium are provided. When is not determined whether low category feature similarity is caused by the angle difference of the target face, whether there is a second face with an angle difference from the to-be-tracked target face greater than a threshold in a second image of a next frame of the first image is determined. In response to no, the target face in the second image is determined and tracked. In response to yes, the second image is taken as the first image, the operation is returned to, the whether there is a second face with an angle difference from the to-be-tracked target face greater than a threshold in a second image of a next frame of the first image is determined.

摘要： The present disclosure relates to systems and methods for object recognition. The systems may obtain an image associated with an object. The systems may determine, using a recognition model, an initial recognition result of the object based on the image. The initial recognition result may include a plurality of initial recognition values corresponding to a plurality of predetermined categories respectively. Each of the plurality of initial recognition values may indicate an initial probability that the object corresponds to a corresponding predetermined category. In response to determining that the initial recognition result satisfies a preset condition, for each of the plurality of predetermined categories, the systems may obtain a reference probability corresponding to the predetermined category. The systems may determine a target recognition result of the object by adjusting the plurality of initial recognition values based on a plurality of reference probabilities corresponding to the plurality of predetermined categories respectively. The target recognition result may include a plurality of target recognition values corresponding to the plurality of predetermined categories respectively. Each of the plurality of target recognition values may indicate a target probability that the object corresponds to a corresponding predetermined category.
