Gangs are a serious threat to the public safety in the United States. We have developed a system known as Gang Graffiti Automatic Recognition and Interpretation (GARI) to help law enforcement identify, track, and analyze gang activities. Gang graffiti components are the segmented graffiti content including symbols, digits, and characters. In this paper, we propose a deep convolutional neural network to classify the graffiti components. We make a comparison between our proposed deep learning method and our previous traditional method. Experimental results show the proposed method reaches 89.3% accuracy with dropout regularization.

  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
