SFAST: A NEW ROBUST REGRESSION BASED COMBINED EDGES AND CORNER DETECTION
2017
International Journal of Advanced Research in Computer Science
Preserved Fulltext
The main feature of this proposed method is to use the edge points and their accumulated information for corner detection, for fast and more accurate results. ...
The experimental results show that the proposed SFAST algorithm is fast, reliable and can be used in environments with noise. ...
The processing time for detection of edges and curve extracting in images with and without noise is summarized in Table 4 .1. ...
