Feature extraction of hyperspectral images for detecting immature green citrus fruit

Yongjun DING, Won Suk LEE, Minzan LI

Frontiers of Agricultural Science and Engineering 2018, Volume 5, Issue 4, Pages 475-484 doi: 10.15302/J-FASE-2018241

Abstract:

At an early immature growth stage of citrus, a hyperspectral camera of 369–1042 nm was employed to acquire 30 hyperspectral images in order to detect immature green fruit within citrus trees under natural illumination conditions. First, successive projections algorithm (SPA) were implemented to select 677, 804, 563, 962, and 405 nm wavebands and to construct multispectral images from the original hyperspectral images for further processing. Then, histogram threshold segmentation using NDVI of 804 and 677 nm was implemented to remove image backgrounds. Three slope parameters, calculated from the pairs 405 and 563 nm, 563 and 677 nm, and 804 and 962 nm were used to construct a classifier to identify the potential citrus fruit. Then, a marker-controlled watershed segmentation based on wavelet transform was applied to obtain potential fruit areas. Finally, a green fruit detection model was constructed according to Grey Level Co-occurrence Matrix (GLCM) texture features of the independent areas. Three supervised classifiers, logistic regression, random forest and support vector machine (SVM) were developed using texture features. The detection accuracies were 79%, 75%, and 86% for the logistic regression, random forest, and SVM models, respectively. The developed algorithm showed a great potential for identifying immature green citrus for an early yield estimation.

Development of Pulsed Radiation Detection Technology

Ouyang Xiaoping

Strategic Study of CAE 2008, Volume 10, Issue 4, Pages 44-55

Abstract:

A direct way to obtain the characteristic information about a nuclear reaction is to detect the rays released from the reaction. To explore the performances of a prompt fission or fusion reaction, sophisticated diagnostic techniques and equipments have been developed and established in China. The diagnostic equipments can measure intense and rapidly changing neutron and gamma rays fluxes in highly mixed neutron-gamma radiation fields. They operate in current mode, and meet a series of special needs in characteristic properties, such as selective radiation sensitivities, a wide dynamic range, a large linearity, a good neutron to gamma ray discrimination, a very fast time response, reliability, etc. Pulse radiation detection has found its various applications in scientific researches, including nuclear reaction mechanism, material analysis, and astronomy study. These diagnostic techniques and their relative detection systems, the design principle, the parameters which are important for current-mode applications are discussesd in th is paper.
