Extraction and Synthesis of Bump Maps from Photographs

چکیده
Extracting fine patterns on real surfaces is a difficult problem. We present a solution to extract such patterns on specular surfaces, and to synthesize similar patterns as bump maps.

A Flexible Noise Model For Designing Maps
In this paper, we propose a flexible noise model for multi-dimensional map synthesis. This model allows the generation of a very varied range of maps, that can be used as perturbation functions, for the generation of color textures, or as bump or displacement maps, for geometric deformation of surface or volume objects. We demonstrate that, because the noise construction is random and procedura...
متن کاملSemi-automatic Road Extraction from Digital Aerial Photographs
By means of the progress in photogrammetry; it is now possible to produce the maps of huge areas more quickly and economically but the production steps are still expensive and time consuming. In recent years, parallel to the development in photogrammetry, more effective methods are researched to make available digitizing line features like roads full automatically or semi-automatically from dig...
متن کاملConceptual Design of n-Butyl Acetate Synthesis Process by Reactive Distillation Using Residue Curve Maps
Residue curve maps are a powerful tool for the preliminary design of Reactive Distillation (RD). In this study, residue curve maps of the n-butyl acetate synthesis reaction were calculated based on the Langmuir–Hinshelwood–Hougen–Watson kinetic and UNIQUAC models to calculate the physical properties of the system. The results showed that the unstable node branch emerged from the n-butyl ace...
متن کاملExploiting User Generated Content for Mountain Peak Detection
We present a system for the classification of mountain panoramas from user-generated photographs followed by identification and extraction of mountain peaks from those panoramas. We have developed an automatic technique that, given as input a geo-tagged photograph, estimates its FOV (Field Of View) and the direction of the camera using a matching algorithm on the photograph edge maps and a rend...
متن کاملIdentification of Fatigue Damaging Events Using a Wavelet-based Fatigue Data Editing Algorithm
This paper describes a technique to identify the important features in fatigue road load data that cause the majority of the total damage. Fatigue damaging events, called bumps, are extracted from the original road load time history using a wavelet-based algorithm, called Wavelet Bump Extraction (WBE). WBE can be used to produce a mission signal that retains most of the fatigue damage whilst pr...
