Title:
TRAINING DATA CREATION ASSISTANCE DEVICE AND TRAINING DATA CREATION ASSISTANCE METHOD
Document Type and Number:
WIPO Patent Application WO/2023/112302
Kind Code:
A1
Abstract:
Provided is a training data creation assistance device which, for an image on which a plurality of defects in an image are reflected, enables the efficient collection/selection of a training image by specifying a feature amount corresponding to each of the defects in a way that a peripheral area of the defect is also considered and by mapping the specified feature amount to a low dimensional space. The training data creation assistance device is characterized by comprising: an image recognition unit which, on the basis of a trained result, extracts feature amounts from an input image, performs image processing with the feature amounts, and outputs a recognition result; a feature amount specification unit which receives an input of one or more prediction results or designated areas from the image recognition unit, and specifies the feature amounts respectively corresponding to the prediction results or designated areas; an inspection result feature amount database in which the feature amounts of the respective prediction results or designation areas are stored; and a dimension reduction unit which performs dimensional reduction on the feature amounts stored in the inspection result feature amount database, and projects the feature amounts into a low-dimensional space, wherein the feature amount specification unit includes an important region calculation unit which, for each of the prediction results or each of the designated areas, obtains an important area that holds peripheral area information including a detected area of the prediction result or the designated area; and a feature amount extraction unit which extracts the feature amount corresponding to each of the prediction results or each of the designated areas by weighting the feature amount extracted by the image recognition unit in the importance area.
