Deep feature learning and latent space encoding for crop phenology analysis

作者:

Highlights:

• Deep learning based piece-wise encoding (PKNet) for effective smoothing of index curves.

• Transformation of pixel-level index curves to get field-level representation (DPGNet)

• Dynamic time wrapping based capsule networks (DTCapsNet) to model curve features.

• Illustration of performance of proposed approaches for crop phenological analysis.
