Symbol Detection for Desired Image Reconstruction

A system comprising:

• one or more computers;
• and
• one or more storage devices storing instructions that, when executed by the one or more computers, cause the one or more computers to perform operations comprising:
• obtaining data indicating an image comprising a latent fingerprint and a template that surrounds the latent fingerprint, and
• obtaining reference data that (i) identifies a known symbol associated with the template, and (ii) includes characteristics of the known symbol;
• processing the image;
• identifying, based on processing the image, one or more candidate regions of the image that are predicted to include the known symbol;
• extracting image characteristics represented within the one or more candidate regions;
• and
• determining, based on the characteristics of the known symbol and the extracted image characteristics represented within the one or more candidate regions, that the one or more candidate regions include the known symbol.

A non-transitory computer-readable storage device encoded with computer program instructions that, when executed by one or more computers, cause the one or more computers to perform operations comprising:

• obtaining data indicating an image comprising a latent fingerprint and a template that surrounds the latent fingerprint, and
• obtaining reference data that (i) identifies a known symbol associated with the template, and (ii) includes characteristics of the known symbol;
• processing the image;
• identifying, based on processing the image, one or more candidate regions of the image that are predicted to include the known symbol;
• extracting image characteristics represented within the one or more candidate regions;
• and
• determining, based on the characteristics of the known symbol and the extracted image characteristics represented within the one or more candidate regions, that the one or more candidate regions include the known symbol.
