Method to determine when to fine-tune raster digitization components

A system comprising

• at least one processor;
• and
• an application that, when executing on the at least one processor, performs operations comprising:
• generating a raster retraining score for a raster segmentation model of a raster digitization engine,
• generating a header retraining score for a header segmentation model of the raster digitization engine,
• generating a curve retraining score for a curve segmentation model of the raster digitization engine, and
• retraining one or more of the raster segmentation model, the header segmentation model, and the curve segmentation model using the raster retraining score, the header retraining score, and the curve retraining score.

A non-transitory computer readable medium comprising instructions executable by at least one processor to perform:

• generating a raster retraining score for a raster segmentation model of a raster digitization engine;
• generating a header retraining score for a header segmentation model of the raster digitization engine;
• generating a curve retraining score for a curve segmentation model of the raster digitization engine;
• and
• retraining one or more of the raster segmentation model, the header segmentation model, and the curve segmentation model using the raster retraining score, the header retraining score, and the curve retraining score.
