A second algorithm used to quantify 16 morphological parameters of roots video recorded at surfaces of minirhizotrons in field experiments is the MR-RIPL, version 2.0. The analysis includes measurements of root length and widths for a sequence of video images. The results are used for analyzing root growth and death rates, and for comparing different agricultural treatments. For one typical experiment, the number of images to be analyzed can reach several thousand per day. MR-RIPL is the program for processing of the minirhizotron images.
Typical image has complex background of soil and roots are bright elongated objects.
WR-RIPL is the program for processing of the washroot images. Typical image has bright background and roots are dark elongated objects.
