Figure 4From: A machine vision system for automated non-invasive assessment of cell viability via dark field microscopy, wavelet feature selection and classificationComparison of original and reconstructed images of live and dead cells. Reconstruction is performed through inverse fast wavelet transform after assignment of zero values to the subimages except (0, 0), (0,1), (3,0) and (3,3) of the wavelet decomposition.Back to article page
