Title:
METHOD AND APPARATUS FOR TARGET OBJECT SEGMENTATION IN IMAGE, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/189913
Kind Code:
A1
Abstract:
A method and apparatus for target object segmentation in an image, and a device and a storage medium. The method comprises: coding a labeled image set to obtain a first coding feature and a second coding feature (S4); respectively performing classification processing on the first coding feature and the second coding feature (S5); performing segmentation processing on the first coding feature (S6); constructing a segmentation loss function and a classification loss function according to a classification processing result and a segmentation processing result, and optimizing a target object segmentation model, to obtain a standard target object segmentation model; and performing target object segmentation on an image to be subjected to segmentation using the standard target object segmentation model, so as to obtain a segmentation result (S9). The method can be applied to lung lesion segmentation, and improve the efficiency and accuracy of target object segmentation in an image when the amount of low-precision labeled data is greater than the amount of high-precision labeled data.
