Abstract: Abstract Due to its high spatial resolution measurements and flexible and contactless experimental setup, shearography, as a non-destructive testing technique, provides effective structural damage identifications. However, this effectiveness can be increased by applying post-processing algorithms… read more here.

Abstract: Abstract. Changes in surface water are normally detected by extracting the water features from individual multispectral (MS) images. We present an approach based on pixel fusion of MS and panchromatic (PAN) bands of multitemporal Landsat… read more here.
