The ‘active’ object is displayed as a black square. The pop-up window shows object information, amount of sub-objects (33) and
further statistics of the image bands, e.g. for the panchromatic band a standard deviation of 50.23. Latter is very characteristic for this
type of mountain forest in this particular area.
Channel 1 = panchromatic band (orthophoto with 1 m resolution)
Channel 2-5 = SPOT4 bands 1-4 (pixel size 23x23 m 2 )
Fig. 1. Screen copy of DELPHI2™. The panchromatic image with 1 m resolution is overlaid with the objects of SPOT4. The image
shows a mountainous forest road with forest stands on the left and right side of the road. The image represents 423x512 m .
A grid of SPOT4 pixels registered as outlined spatial objects, each containing 529 (= 23x23) orthophoto pixels, are lying on
top of the sub-objects from the segmentation process using the panchromatic band.
