Figure 2From: A machine vision system for automated non-invasive assessment of cell viability via dark field microscopy, wavelet feature selection and classificationPerformance evaluation of the MVS. Correlation analysis of the results given by the gold standard and by the MVS (a) using raw image patches; (b) using the complete set of 32 wavelet packet features; (c) using a selected subset of 12 features. It can be concluded that feature extraction and selection have significantly enhanced the system.Back to article page
