Abstract: A method of validating an inferential model for operation on an inference data set is provided. The method includes extracting a first distribution of values of a first parameter from the inference data set, extracting a second distribution of values of the first parameter from a validating data set used to validate the inferential model, determining a first parameter distance between the extracted first distribution and the extracted second distribution, and validating the inferential model for operation on the inference data set based on satisfaction of a validation condition, the satisfaction of the validation condition being based on the determined first parameter distance.

Abstract: A medical image processing method, performed by a computer, for measuring the spatial location of a point on the surface of a patient's body including: acquiring at least two two-dimensional image datasets, wherein each two-dimensional image dataset represents a two-dimensional image of at least a part of the surface which comprises the point, and wherein the two-dimensional images are taken from different and known viewing directions; determining the pixels in the two-dimensional image datasets which show the point on the surface of the body; and calculating the spatial location of the point from the locations of the determined pixels in the two-dimensional image datasets and the viewing directions of the two-dimensional images; wherein the two-dimensional images are thermographic images.
