change detectionprincipal component analysis (PCA)percent difference (PD)fusionIn remote sensing, for applications as environment monitoring, change detection based on image processing is one of the most important techniques. To reach high performance various techniques of fusion are exploited using a ...
How to use PCA in remote sensing? Running a principal component analysis on three bands was useful because we found the third component did not add much information. What about a 10-band multispectral image? Or even 100 or 200 bands (hyperspectral imagery)? This is where PCA is really usefu...
