METHOD FOR PROCESSING INSAR IMAGES TO EXTRACT GROUND DEFORMATION SIGNALS

摘要

The invention relates to a method for processing time series of noisy images of a same area, the method comprising: generating a set of time series of images from an input image time series (RI[t]) by combining by first linear combinations each pixel (PX[i,j]) of each image of the input image time series with selected neighboring pixels in the image and in an adjacent image of the input image time series; applying filtering operations (FPs, s=1-3, 5, 7-11) in cascade to the set, each filtering operation combining each pixel of each image of each time series of the set by second linear combinations with selected neighboring pixels in the image and in an adjacent image in each time series of the set; performing an image combination operation (SLs, s=4, 6) to reduce each time series of the set to a single image; introducing a model image (EM) of the area as a filtered image in the set; and combining each image in the set into an output image (PI), by third linear combinations.
