Enhancing Textured Digital Elevation Models Using Photographs
We present a method for enhancing the visual quality of existing digital elevation models textured with orthophotos, using a sparse set of unordered, high resolution photographs. After an initial manual selection of correspondence points, we automatically register the input photographs to the given terrain data set using robust imagebased modeling techniques. To combine the geo-registered image...
متن کاملBuilding extraction from digital elevation models
To extract buildings from Digital Elevation Models, we define a point process whose points represent buildings. We then define a density for this point process which is split into two parts, consisting in an ”internal field” that allows us to model the prior knowledge we have on patterns of buildings in urban areas and an ”external field” that makes the point process fit the data. We then use a...
متن کاملDigital Elevation Models from Contour Lines
♦ Sampling density along the contours Interpolation of the irregular set of data points to a regular grid Valid theorems for sampling density have only recently been developed. Interpolation methods have to deal with the 'flat triangle' problem, as well as preservation of the accuracy of slope. Meaningful slopes are increasingly important in applications such as soil erosion and run-off modelli...
متن کاملParallelization of Rich Models for Steganalysis of Digital Images using a CUDA-based Approach
There are several different methods to make an efficient strategy for steganalysis of digital images. A very powerful method in this area is rich model consisting of a large number of diverse sub-models in both spatial and transform domain that should be utilized. However, the extraction of a various types of features from an image is so time consuming in some steps, especially for training pha...
متن کاملTemperature Mapping Using Ultrasound Digital Images
Introduction: The success of hyperthermia depends on the accuracy of the temperature monitoring in the tumor and the surrounding normal tissue. In this study, the temperature changes were determined by computing the speckle displacement in the ultrasound digital images. Speckle tracking algorithm was used to compute the displacement. Materials and Methods: The experiment was perf...
