Query: From Species to Cultivar: Soybean Cultivar Recognition using Multiscale
  Sliding Chord Matching of Leaf Images   Leaf image recognition techniques have been actively researched for plant
species identification. However it remains unclear whether leaf patterns can
provide sufficient information for cultivar recognition. This paper reports the
first attempt on soybean cultivar recognition from plant leaves which is not
only a challenging research problem but also important for soybean cultivar
evaluation, selection and production in agriculture. In this paper, we propose
a novel multiscale sliding chord matching (MSCM) approach to extract leaf
patterns that are distinctive for soybean cultivar identification. A chord is
defined to slide along the contour for measuring the synchronised patterns of
exterior shape and interior appearance of soybean leaf images. A multiscale
sliding chord strategy is developed to extract features in a coarse-to-fine
hierarchical order. A joint description that integrates the leaf descriptors
from different parts of a soybean plant is proposed for further enhancing the
discriminative power of cultivar description. We built a cultivar leaf image
database, SoyCultivar, consisting of 1200 sample leaf images from 200 soybean
cultivars for performance evaluation. Encouraging experimental results of the
proposed method in comparison to the state-of-the-art leaf species recognition
methods demonstrate the availability of cultivar information in soybean leaves
and effectiveness of the proposed MSCM for soybean cultivar identification,
which may advance the research in leaf recognition from species to cultivar.
