WIPO Patent Application WO/2024/045819
Kind Code:
A1
Abstract:
The present application relates to the technical field of computer visions. Disclosed are a lesion area determining method and apparatus, and a model training method and apparatus. The lesion area determining method comprises: sampling at least two first instance images from a pathological image in a first sampling mode (310); on the basis of feature information extracted from the at least two first instance images, determining a candidate lesion area in the pathological image (320); sampling at least two second instance images from the candidate lesion area in a second sampling mode, the degree of overlap between the second instance images being greater than the degree of overlap between the first instance images (330); and on the basis of feature information extracted from the at least two second instance images, determining lesion indication information of the pathological image, the lesion indication information being used for indicating a lesion area in the pathological image (340). In the present application, the consumption of human resources is reduced, and the cost of determining the lesion area is saved.
