GUEVARA FLORES, Diana Karina; PEREZ TELLEZ, Fernando  and  PINTO AVENDANO, David Eduardo. Analysis of Automatic Annotations of Real Video Surveillance Images. Comp. y Sist. [online]. 2020, vol.24, n.2, pp.597-606.  Epub Oct 04, 2021. ISSN 2007-9737.  https://doi.org/10.13053/cys-24-2-3393.

The results of the analysis of the automatic annotations of real video surveillance sequences are presented. The annotations of the frames of surveillance sequences of the parking lot of a university campus are generated. The purpose of the analysis is to evaluate the quality of the descriptions and analyze the correspondence between the semantic content of the images and the corresponding annotation. To perform the tests, a fixed camera was placed in the campus parking lot and video sequences of about 20 minutes were obtained, later each frame was annotated individually and a text repository with all the annotations was formed. It was observed that it is possible to take advantage of the properties of the video to evaluate the performance of the annotator and the example of the crossing of a pedestrian is presented as an example for its analysis.

Keywords : Automatic annotation; semantic analysis; surveillance images.
