Marker hiding methods: Applications in augmented reality

© 2015 Taylor & Francis Group, LLC.In augmented reality, the markers are noticeable by their simple design of a rectangular image with black and white areas that disturb the reality of the overall view. As the markerless techniques are not usually robust enough, hiding the markers has a valuable usage, which many researchers have focused on. Categorizing the marker hiding methods is the main motivation of this study, which explains each of them in detail and discusses the advantages and shortcomings of each. The main ideas, enhancements, and future works of the well-known techniques are also comprehensively summarized and analyzed in depth. The main goal of this study is to provide researchers who are interested in markerless or hiding-marker methods an easier approach for choosing the method that is best suited to their aims. This work reviews the different methods that hide the augmented reality marker by using information from its surrounding area. These methods have considerable differences in their smooth continuation of the textures that hide the marker area as well as their performance to hide the augmented reality marker in real time. It is also hoped that our analysis helps researchers find solutions to the drawbacks of each method. © 201

AR marker hiding based on image inpainting and reflection of illumination changes

ISMAR 2012: IEEE International Symposium on Mixed and Augmented Reality , Nov 5-8, 2012 , Atlanta, GA, USAThis paper proposes a new method of diminished reality which removes AR markers from a user's view image in real time. To achieve natural marker hiding, assuming that an area around a marker is locally planar, the marker area in the first frame is inpainted using the rectified image to achieve high-quality inpainting. The unique inpainted texture is overlaid on the marker region in each frame according to camera motion for geometric consistency. Both global and local luminance changes around the marker are separately detected and reflected to the inpainted texture for photometric consistency
