In this project thresholding and watershed algorithms are applied to count freshwater snails, and quantify shape and shell-pigmentation of individual snails.
In this project, first, a mask is set around tray, the reference is set manually (the detection algorithm only works on reference cards with clear boundaries, and not on “continuous” mm-paper), and then thresholding and watershed algorithm are applied. Remaining overlap is removed with the
edit_contour tool, and
detect_contour is used a once more to determine the final specimen contours. In the second step, the configuration file is modified to add
compute_texture_features, followed by a “silent run”
