1. A computer-implemented method for determining a material property of a foam sample comprising:
(a) providing a representation of the sample, wherein the representation is generated from images showing the inner structure of the sample by edge detection, surface detection, or segmenting the images by applying a threshold algorithm and receiving a type of material for each phase in the sample;
(b) extracting at least one structural feature from the representation wherein the at least one structural feature comprises walls, struts, or nodes,
wherein the walls correspond to material in between two particles of a different material or between two pores,
wherein the struts correspond to material in between three particles of a different material or between three pores, and
wherein the nodes correspond to material in between four particles of a different material or between four pores;
(c) providing the at least one structural feature to a material model suitable for obtaining at least one material property from the structural feature, wherein the at least one material property comprises a mechanical property, a thermal property, an electrical property, or an optical property;
(d) outputting the at least one material property received from the material model; and
(e) monitoring and/or controlling the at least one material property of the sample.
