The paper presents the experiments of compost images analysis carried out with two types of digital cameras working in daylight and ultraviolet light. The data collected with two cameras were analysed with the usage of neural network model (using part of application Statistica v. 8.0). The results of image analysis were combined also with the results of(More)
The aim of the study was to develop a neural model for the identification of mechanical damage in maize caryopses based on digital photographs. The author has selected a set of features that distinguish between damaged and healthy caryopses. The study has produced an artificial neural network of a multilayer perceptron type whose identification capacity(More)
