Multilayer Perceptrons applied to Automatic Microfossil Detection in Somosaguas Sur paleontologic site (Pozuelo de Alarcón, Madrid, Spain)

Microfossils are very important in order to establish terrain correlations, allowing to determinate the age of geological layers with a high grade of accuracy. They are also the fund of any micropaleontological studies. Actual techniques used to extract microfossils are manual, and require of a high amount of time and human resources. This fact make interesting the study of other more complex techniques, that speed up the extraction of the microfossils, allowing to reduce the required human resources for this task, incrementing the volume of analyzed terrain, and, consequently, improving the accuracy of the microfossil studies. The work presented in this paper evaluates the use of Multilayer Perceptrons in order to help in the microfossil extraction tasks. The analyzed material has been obtained from Somosaguas paleontological site, in Madrid (Spain). Key-Words: Multilayer Perceptron, Neyman-Pearson, Microfossil detection, Somosaguas site.
