Summary: Abstract. This paper presents a new method based on digital image processing techniques such as color transformations and mathematical morphology, as well as on some specialist knowledge, to provide estimates for the lengths of rice panicles that have been removed from the plant. Results show that the method estimates are at least as accurate as those obtained by manual measurements, being robust under a wide variety of imaging setups and conditions. Another major advantage presented by this approach is the ability of providing estimates for several panicles at once, either by processing several image files in a single batch, by processing images containing a large number of panicles, or both.
