The use of lightweight and cheap UAVs to detect the health of forests and identify the tension of planted can be useful to prevent the spread of pests and diseases. In the present research, a lightweight quadcopter drone with a 12-megapixel camera, visible light range was used. This UAV was emploied to detect leaf tension of pure Quercus Castanifolia plantation, pure Acer Velutinum and their mi...

The selection of a suitable feature is an important and indispensible issue in real-time surveillance systems employing a network of cameras to achieve rapid and accurate results. We have used the concept of color image histograms, as a simple but efficient method, to track people in different cameras in this research. Employing the image histogram for tracking may not be robust as it is sensit...
