COASTAL DIGITAL SURFACE MODEL ON LOW CONTRAST IMAGES
UAV low contrast DSM coastal survey MicMac
2015/9/21
Coastal sandy environments are extremely dynamic and require regular monitoring that can easily be achieved by using an unmanned aerial system (UAS) including a drone and a photo camera. The acquired ...
A NOVEL APPROACH FOR EDGE DETECTION OF LOW CONTRAST SATELLITE IMAGES
Sobel Edge Detector Fractional Order Differentiator Chebyshev Polynomial based Approximation Satellite Images
2015/4/1
Discrimination between texture edges and geometrical edges is very difficult in low contrast images. Satellite images are low contrast images. It is important to extract the edges that are not clearly...
Effect of Edge-Preserving Adaptive Image Filter on Low-Contrast Detectability in CT Systems: Application of ROC Analysis
CT Systems ROC Analysis
2009/9/4
Objective. For the multislice CT (MSCT) systems with a larger number of detector rows, it is essential to employ dose-reduction techniques. As reported in previous studies, edge-preserving adaptive im...
