SMAS


Soil Morphological Analysis software is a C++, Python and CUDA (Compute Unified Device Architecture) program that is used to do statistical analysis of soil columns. SMAS pipeline process is divided into eight components from image processing to data analysis. SMAS was developed as a collaboration between the Universidad Nacional Autónoma de México, The University of Auckland and the Institut polytechnique de Grenoble.
