Recently, mechanical condition monitoring in induction motors has become an important research area because of its relevance in different industrial applications. Infrared thermography has been considered for improving the monitoring of induction motors with the advantage of being a non-invasive technique and having a wide range of analysis. In this work, infrared thermography is used as complementary...
We present an optical processor capable to perform partial second derivatives of an image working with partially coherent illumination. The proposed system utilizes a liquid crystal display, onto which images to be derived are displayed. The method is based on the capacity of these devices to generate simultaneously a contrast reverted replica of the image displayed on it. A positive replica of original...
Accurately counting people waiting at bus stops is essential for automated bus fleet scheduling and dispatch. Estimating the passenger demand in regular open bus stops is a nontrivial problem because of the varying conditions, such as illumination, crowdedness, people poses, to name a few. This paper presents a simple, but very effective approach to estimate the passenger count using people density...
