Title:
METHOD AND APPARATUS FOR DETECTING TARGET OBJECT IN IMAGE, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/189912
Kind Code:
A1
Abstract:
A method and apparatus for detecting a target object in an image, and an electronic device and a storage medium, which relate to image analysis technology. The method comprises: performing noise reduction processing on a training image so as to obtain a standard training image, and performing target object detection on the standard training image using a target object detection model so as to obtain predicted centre point information, predicted size information and predicted boundary information; constructing a target loss function, calculating a loss value, and optimizing the target object detection model according to the loss value so as to obtain a standard target object detection model; and acquiring a target object image to be subjected to detection, and performing image detection on said target object image using the standard target object detection model so as to obtain a standard detection result. In addition, the method further relates to blockchain technology, and the standard detection result can be stored in a blockchain node. The method can be applied to the detection of lesion information in a medical image. By means of the method, the efficiency and accuracy of detecting a target object in an image can be improved.
