Mob scene filter

Videos are getting high-resolution enough to understand its detail. Improvement of resolution, however, might accelerate privacy problems. High-resolution videos enable people to identify an individual easily. Image processing techniques, such as the mosaic and the blur, have been used to protect privacy. These techniques, however, make people difficult to understand the contexts of the video. So an advanced privacy protecting technique is needed without losing the contexts of the video. We focus on changing the facial appearance of characters on the video for protecting their privacy without failing the information from facial expressions. We propose the system, called Mob Scene Filter that changes not only the facial textures but also the arrangement of the facial regions and their sizes.
