Description: Use morphological image processing and edge detection
        algorithms to automatically measure tree ring widths on digital
        images. Users can also manually mark tree rings on species with
        complex anatomical structures. The arcs of inner-rings and
        angles of successive inclined ring boundaries are used to
        correct ring-width series. The package provides a Shiny-based
        application, allowing R beginners to easily analyze tree ring
        images and export ring-width series in standard file formats.
