One of the most important components in the value of gemstones is how clean and free of inclusion the stone is. Based on the broad used technique of visual inspection, the designed expert system automatically checks the surface of the ruby samples and detects three main components: ruby, calcite and mica. Based on this data, the system was able to assess the amount of clean ruby surface of the specimens...
The amber gemstones classification system is proposed and described in this paper. The amber data used in experiments are collected by amber art craft industry experts and divided manually into 30 classes. The presented investigations were care out in order to find out most accurate and fast classifier for online amber sorting application. QDA, KNN, RBF, and decision tree classifiers were tested....
The results of design and investigation on a human gesture recognition system, based on a Kinect sensor, are presented in this paper. In the presented research, we use a Kinect device as a 3D data scanner. Therefore, the 3D coordinates are calculated directly from depth images. The system's hardware description and computation method for 3D human gesture identification are presented in this study...
