An important, potential application of image-based techniques is to create photo-realistic image-based environments for interactive walkthrough. However, existing image-based studies are based on different assumptions with different focuses. There is a lack of a general framework or architecture for evaluation and development of a practical image-based(More)
The use of multiple panoramic images for walkthrough applications is attracting more attention in recent years. The geometric proxy, which can be recovered from wide-baseline images can be used to reduce the sampling rate. However correspondence matching across widely separated panoramic images requires searching a large disparity range, which can(More)
Omni-directional images are widely used in image-based walkthrough applications, in which camera pose recovery is one of the initial and important processes. Existing methods may recover camera pose of omni-directional images from lines. However, it may not work well when there is insufficient scene structure in the images. In addition, existing methods(More)
BACKGROUND Biopsy procedures and diagnostic histopathology are rarely used by general dental practitioners (GDPs) compared with dental specialists. The aim of this study was to investigate the usage patterns and views of GDPs and specialists in Brisbane on these procedures. METHODS An analysis was carried out on 1027 oral biopsy accessions at a private(More)
This paper presents a data-driven, simple cluster-and-label approach using optimized count-based methods for word-level language identification for a large domain-specific multilingual diachronic corpus of periodicals published at least yearly between 1864 and 2014 in Switzerland. Our system requires no annotated data or training, only minimal human effort(More)
