Reference data set for camera spectral sensitivity estimation

Rank-based camera spectral sensitivity estimation.

In order to accurately predict a digital camera response to spectral stimuli, the spectral sensitivity functions of its sensor need to be known. These functions can be determined by direct measurement in the lab-a difficult and lengthy procedure-or through simple statistical inference. Statistical inference methods are based on the observation that when a camera responds linearly to spectral st...

A Ground Truth Data Set for Nikon Camera’s Spectral Sensitivity Estimation

Camera spectral sensitivity functions are obtained either by measurements in the laboratory or via estimation algorithms. A procedure for camera spectral sensitivity measurement is explained in this article, which aims to provide high accuracy ground-truth values with known uncertainty. The measurements were carried out on a Nikon D5100 camera at the National Physical Laboratory, London. We use...

Performances of classic and weighted versions of some selected methods in estimation of spectral data from camera responses

sensitivity evaluation of spectral vegetation indices using sensitivity functions for stand volume estimation

identification of the best vegetation indices (vis) for use in quantitative analyzes of vegetation is one of the important issues for ecologists. the objective of this study was sensitivity evaluation of vegetation indices to a stand volume for identification of the best vegetation index (vi) in stand volume estimation using a statistical sensitivity method. also, another objective of this stud...

SPOT-5 Spectral and Textural Data Fusion for Forest Mean Age and Height Estimation

Precise estimation of the forest structural parameters supports decision makers for sustainable management of the forests. Moreover, timber volume estimation and consequently the economic value of a forest can be derived based on the structural parameter quantization. Mean age and height of the trees are two important parameters for estimating the productivity of the plantations. This research ...
