We present a novel framework for precisely estimating dense depth maps by combining 3D lidar scans with a set of uncalibrated camera RGB color images for the same scene. Rough estimates for 3D structure obtained using structure from motion (SfM) on the uncalibrated images are first co-registered with the lidar scan and then a precise alignment between the datasets is estimated by identifying correspondences...
The Cincinnati Waterfront Daguerreotype Panorama, owned by the Public Library of Cincinnati and Hamilton County, was brought to George Eastman House in 2007 for conservation treatment. At George Eastman House the plates were imaged under a microscope to capture details at nearly their full resolution and composited mosaic images comprised of 756 images per plate were created. Although the mosaic yields...
We propose an analytic method to overcome the trade-off between the spatial and tonal resolution of traditional clustered dot halftones. Continuous phase modulated halftones that allow variations in screen frequency in different regions of the printed image are employed and halftone screen frequency is varied according to the frequency content of the image to be halftoned. The method, which we term...
