Abstract


Metabolic dysfunction-associated steatotic liver disease affects approximately 30% of the global population. Its clinical course may progress to severe conditions such as cirrhosis and hepatocellular carcinoma. In this context, thermography has emerged as a non-invasive, yet challenging, method for screening for the disease. This study compared temporal, spatial, and spatio-temporal integration approaches for liver disease classification using thermal image time series. The experiments achieved a precision of 66% and sensitivity of 73%, demonstrating that preserving temporal evolution along with spatial patterns results in better performance.
