BUILDING ROOF BOUNDARY EXTRACTION FROM LiDAR AND IMAGE DATA BASED ON MARKOV RANDOM FIELD
Markov Random Field LiDAR Aerial images Building roof boundary
2017/7/12
In this paper a method for automatic extraction of building roof boundaries is proposed, which combines LiDAR data and highresolution aerial images. The proposed method is based on three steps. In the...
ANALYSIS AND VALIDATION OF GRID DEM GENERATION BASED ON GAUSSIAN MARKOV RANDOM FIELD
DEM Gaussian Markov Random Field Spatial Modelling
2016/7/8
Digital Elevation Models (DEMs) are considered as one of the most relevant geospatial data to carry out land-cover and land-use classification. This work deals with the application of a mathematical f...

Image Classification Spatial Dependence Markov Random Field Pixel Interaction Parameter Estimation
2014/4/24
Markov random field (MRF) is an effective method for description of local spatial-temporal dependence of image and has been
widely used in land cover classification and change detection. However, ex...
A JOINT PIXEL AND REGION BASED MULTISCALE MARKOV RANDOM FIELD FOR IMAGE CLASSIFICATION
Image segmentation Region based MRF Pixel based MRF High resolution image Multiscale analysis Watershed transform
2014/4/28
MRF model is recognized as one of efficient tools for image classification. However, traditional MRF model prove to be limited for high resolution image classification. This paper presents a joint pix...
