Abstract

One of the most interesting and everyday natural phenomenon is the formation of different patterns after the evaporation of colloidal droplets deposited on a solid surface. Analysing dried patterns resulted from biological liquids, such as blood, has recently gained a lot of attention, experimentally and theoretically, due to their wide applications in biomedicine, forensic science and many others. This work analyses a large database of dried blood droplet images with different five experimental conditions objectively and quantitatively by developing sophisticated image processing analysis routines and optimising a multivariate statistical machine learning algorithm. An analysis of various measured physiological parameters is also investigated.  We have seen that when our machine learning algorithm, which is an optimisation to a statistical model that combines Principal Component Analysis (PCA) as an unsupervised learning method and Linear Discriminant Analysis (LDA) as a supervised learning method, is applied on the logarithmic power spectrum of the images, it can provide a very good prediction accuracy, reaches to 95%, to discriminate the blood conditions, provided we undertake an average over all the images taken per volunteer per condition.
