Parameters

Example (HDevelop)

* Read image for initialization:
read_image (InitImage, 'xing/init')
* Initialize BgEsti dataset with
* fixed gains and threshold adaption:
create_bg_esti(InitImage,0.7,0.7,'fixed',0.002,0.02, \
               'on',7.0,10,3.25,15.0,BgEstiHandle)
* Read the next image in sequence:
read_image(Image0, 'xing/xing001')
* Estimate the background:
run_bg_esti(Image0,ForegroundRegion1,BgEstiHandle)
* Display the foreground region:
dev_display (ForegroundRegion1)
* Read the next image in sequence:
read_image(Image1, 'xing/xing002')
* Estimate the background:
run_bg_esti(Image1,ForegroundRegion2,BgEstiHandle)
* Display the foreground region:
dev_display (ForegroundRegion2)
* etc.
* - End of background estimation -
* Close the dataset:
close_bg_esti(BgEstiHandle)
