1. A method for inspecting a load in a container, comprising: classifying one or more patches of a digitized inspection image, the digitized inspection image being generated by an inspection system configured to inspect the container by transmission of inspection radiation from an inspection radiation source to an inspection radiation detector through the container, wherein the classifying comprises: extracting one or more texture descriptors of a patch, and classifying the patch, by comparing the one or more extracted texture descriptors of the patch to one or more reference texture descriptors corresponding to one or more classes of reference items, the one or more reference texture descriptors of each class of reference items being extracted from one or more reference images of the one or more reference items.
