Towards the characterization of crop and weeds at leaf scale: A large comparison of shape, spatial and textural features
Autor: Jehan-Antoine Vayssade, Gawain Jones, Jean-Noël Paoli
Publikováno v: Smart Agricultural Technology, Vol 5, Iss , Pp 100245- (2023)
In the context of crop and weeds discrimination, different methods are used to detect and classify plants from an acquisition system. Various estimators and descriptors are commonly used to characterize plants within an image. However, the available

DeepIndices: Remote Sensing Indices Based on Approximation of Functions through Deep-Learning, Application to Uncalibrated Vegetation Images
Autor: Jehan-Antoine Vayssade, Jean-Noël Paoli, Christelle Gée, Gawain Jones
Publikováno v: Remote Sensing, Vol 13, Iss 12, p 2261 (2021)
The form of a remote sensing index is generally empirically defined, whether by choosing specific reflectance bands, equation forms or its coefficients. These spectral indices are used as preprocessing stage before object detection/classification. Bu
