摘要： The embodiments of the present disclosure provide a method and an apparatus for determining object classification. The method may include: performing, by a target detection network, an object detection on a first image, to obtain a first classification confidence of a target object involved in the first image; obtaining an object image comprising a re-detection object from the first image, and performing, by a filter, the object detection on the object image, to determine a second classification confidence of the re-detection object; wherein the re-detection object is the target object whose first classification confidence is within a preset threshold range; correcting the first classification confidence of the re-detection object based on the second classification confidence to obtain an updated confidence; determining a classification detection result of the re-detection object based on the updated confidence.

摘要： A target detection method and apparatus, an electronic device and a computer-readable storage medium are provided by the embodiments of the present disclosure. The method includes: obtaining a detection result by performing a target detection on a to-be-detected image, wherein the detection result comprises a target classification to which a target object involved in the to-be-detected image belongs and position information corresponding to the target object involved in the to-be-detected image; cropping out a proposal image involving the target object from the to-be-detected image based on the position information; determining a confidence that the target object belongs to a target classification based on the proposal image; and deleting, in response to that the confidence is less than a preset threshold, an information item concerned the target object from the detection result.
