Z. Wang et al., IDENTIFICATION AND SEPARATION OF MICROPROPAGATED SUGARCANE SHOOTS BASED ON THE HOUGH TRANSFORM, Transactions of the ASAE, 41(5), 1998, pp. 1535-1541
A Hough transform-based computer algorithm was developed to identify s
ugarcane shoots as straight lines in a micropropagated Stage 2 sugarca
ne shoot clump image. An are-based shoot identification method develop
ed previously was tested after changing the lighting from fluorescent
to incandescent which improved contrast between stems and leaves. This
method was then compared to the Hough transform method. The Hough tra
nsform algorithm correctly identified 93% of total shoots versus 82% f
or the are method missed 7% of the shoots versus 18% for the are metho
d, and improperly identified non-shoots as shoots 6% of the time versu
s 7% for the are method.
