Various space agencies are interested in monitoring the passage of meteors in Earth's atmosphere, such as NASA, that developed the CAMS project (Cameras for Allsky Meteor Surveillance). In Brazil, the EXOSS (Exploring the Southern Sky) organization uses citizen science to monitor the night sky, relying on low budget stations that are mounted by professional and amateur astronomers across the country. This work proposes to use deep neural networks in identifying the presence of meteors in images captured by the EXOSS system. A program for classifying in real time images as meteors or not meteors will be developed, expanding on a previous work and applying it in a practical setting. Taking advantage of the large quantity of data captured by EXOSS, different approaches to the problem will be studied and compared, such as training the networks solely on EXOSS data and using transfer learning. Deep neural networks are currently the best performing algorithms in the fields of image classification, text translation and voice recognition, representing a relevant research field. The work accomplished in this Scientific Initiation project will contribute to the country's research in meteor detection and deep neural networks, and will also directly aid the monitoring of meteors in Brazil.
