Hyperspectral Properties Of Date Palm Trees (Phoenix Dactylifera L.), Mohamed Ali Saeed Ahmed Al Abdouli Nov 2020

Hyperspectral Properties Of Date Palm Trees (Phoenix Dactylifera L.), Mohamed Ali Saeed Ahmed Al Abdouli

Theses

The goal of this study is to classify the Date Palm varieties based on hyperspectral signature technology since it is difficult to identify the Date Palm cultivars without fruits. It will also help to obtain the hyperspectral signature for different types of date palm trees. Moreover, it also assists to determine the wavelength fingerprint of each cultivar and to recommend the best classification protocol differentiating among different cultivars based on spectral signature. Utilizing the Hyperspectral imaging technology precisely on the leaves of different Date Palm cultivars, thus facilitating identification of date palm cultivars without the fruits and make the spatial …


Hyperspectral Imaging Evaluation Of The Freshness Of Mushrooms (Agaricus Bisporus), Meera Hmoud Saeed Aldhaheri May 2019

Hyperspectral Imaging Evaluation Of The Freshness Of Mushrooms (Agaricus Bisporus), Meera Hmoud Saeed Aldhaheri

Theses

Hyperspectral imaging (HSI) is a non-destructive analytical tool that can be used for sensing multiple attributes of foods. This thesis evaluates the application of HSI for measuring the freshness of the mushroom Agaricus bisporus (A. bisporus) in comparison with traditional seed methods. Three separate experiments were performed with 135 mushroom samples stored either in packed or unpacked conditions for 11 days. The overall results suggest that the HSI spectral region between 400 and 1000 nm is suitable for the inspection of mushroom freshness. Two distinguishing variables that aligned with physicochemical and microbiological analysis were recognized. Moisture loss was the main …
