Erratum: A Variational Approach to Video Segmentation for Botanical Data

In this erratum, we correct the previous explanation of the data-collection procedure as outlined in [SIAM J. Sci. Comput., 29 (2007), pp. 1550–1566]. DOI. 10.1137/070700036 In [1], the authors incorrectly described the data-collection procedure for capturing the botanical fluorescence data. • In the abstract, the sentence “In order to visualize a particular leaf’s stomatal aperture, an experimentalist injects the leaf with a dye so that it fluoresces.” should be reworded as “In order to visualize a particular leaf’s stomatal aperture, fluorescence is induced corresponding to changes in average stomatal aperture size, and the data are collected at regular intervals.” • On page 2, in the first full paragraph, the sentence “A dye is injected into the leaf that fluoresces when the stomata close, and stomatal dynamics are initiated by decreasing the concentration of H2O on the upper surface of the leaf.” should be replaced with “Chlorophyll molecules in an intact leaf that are excited by visible light, upon deexcitation, dissipate part of the excitation energy as infrared fluorescence. Stomatal dynamics are then initiated by decreasing the concentration of H2O on the upper surface of the leaf.” These changes reflect that the data-collection procedure used for the data in this work was updated, and the data actually shown in this work are derived from the updated procedure.
