Risk assessment based on patient similarity determined using image analysis

A system for risk assessment, comprising:

• a memory and at least one processor coupled to the memory, wherein the at least one processor is configured to:
• receive one or more images of a plurality of lesions captured from a body of a target person;
• generate one or more digital signatures based on the one or more images from the body of a target person;
• compare the generated one or more digital signatures to digital signatures of respective reference persons, wherein the processor is further configured to measure similarities between the generated one or more digital signatures and the digital signatures of the respective reference persons;
• and
• determine a risk factor for the target person of developing a disease based on the measured similarities and predetermined risk factors of developing the disease for the reference persons.

A computer program product for risk assessment, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising:

• receiving one or more images of a plurality of lesions captured from a body of a target person;
• generating one or more digital signatures based on the one or more images from the body of the target person;
• comparing the generated one or more digital signatures to digital signatures of respective reference persons, wherein the comparing comprises measuring similarities between the generated one or more digital signatures and the digital signatures of the respective reference persons;
• and
• determining a risk factor for the target person of developing a disease based on the measured similarities and predetermined risk factors of developing the disease for the reference persons.
