See the paper abstract:
Due to amendments in Brazilian law, the possession of files containing child and teen pornography began to be crime and the need to detect this type of content at crime scenes increased. With this objective, the NuDetective Forensic Tool has been assisting forensic examiners to conduct such analysis in a timely manner. However, with the evolution of digital cameras and camcorders, image files are being produced with higher resolutions, which may result in an undesirable delay of processing these files. This work presents an approach to optimize the automatic nudity detection provided by NuDetective Forensic Tool by reducing the images resolution. Several evaluation experiments were performed and the results showed that it is possible to reduce the runtime in almost 90%, without significant changes in the nudity detection results.
