Adaptive Building Edge Detection by Combining LIDAR Data and Aerial Images
LIDAR Aerial image Fusion Edge detection Building extraction DEM
2015/11/20
The building edge detection plays a key role during building extraction, which is important and necessary for building description. The edges detected from aerial images have high horizontal accuracy ...
Wavelet Speckle Reduction for SAR Imagery Based on Edge Detection
Image processing Filtering Feature detection Geography Image understanding
2015/11/20
This paper introduces a wavelet transform speckle reduction algorithm for Synthetic Aperture Radar (SAR) imagery based on edge detection. Existing speckle algorithm can efficiently reduce the speckle ...
EDGE-BASED REGISTRATION FOR AIRBORNE IMAGERY AND LIDAR DATA
Aerial Imagery Building, Detection, LIDAR, Model, Registration
2014/4/28
Aerial imagery and LIDAR points are two important data sources for building reconstruction in a geospatial area. Aerial imagery implies building contours with planimetric features; LIDAR data explicit...
In this paper, we proposed a new edge-directed image interpolation algorithm which can preserve the edge features and natural appearance of images efficiently. In the proposed scheme, we first get a c...
2D to 3D Convertion Based on Edge Defocus and Segmentation
2D to 3D Convertion Edge Defocus Segmentation
2010/12/20
This paper presents a depth estimation method which converts two-dimensional images into three-dimensional data. Based on two-dimensional wavelet analysis of Lipschitz regularity for defocus estimatio...
An edge-based median filtering algorithm with consideration of motion vector reliability for adaptive video deinterlacing
filtering algorithm motion vector reliability
2010/12/16
Because of its ability to preserve signal edges while filtering out impulsive noises, median filtering is widely used in signal processing applications, e.g. deinterlacing. An edgebased
median filter...
