Its main strength is to classify hemispherical
photographs of the plant canopy with algorithms specially developed for
such a task and well documented in
Díaz and Lencinas (2015) <doi:10.1109/lgrs.2015.2425931> and
Díaz and Lencinas (2018) <doi:10.1139/cjfr-2018-0006>. It supports
non-circular hemispherical photography.

non-circular hemispherical photography, such as those acquired with
15 mm lenses or with auxiliary fish-eye lenses attached to mobile devices.
Most of the functions also support restricted view photography.

Different Numeric Optimizations to Estimate Parameter
Coefficients
Akshay Suresh, Siddhesh Acharekar, Hsiangwei Chao, Shiva Yogi Biradar
There are different numeric optimizations which are used in order to estimate coefficients in models such as linear regression and neural networks. This package covers parameter estimation in linear regression using different methods such as batch gradient descent, stochastic gradient descent, minibatch gradient descent and coordinate descent.
