示例（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/xing000')
* 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/xing001')
* Estimate the background:
run_bg_esti(Image1,ForegroundRegion2,BgEstiHandle)
* Display the foreground region:
dev_display (ForegroundRegion2)
* etc.
* Change only the gain parameter in dataset:
get_bg_esti_params(BgEstiHandle, Syspar1, Syspar2, \
GainMode, Gain1, Gain2, AdaptMode,\
MinDiff, StatNum, ConfidenceC, TimeC)
set_bg_esti_params(BgEstiHandle, Syspar1, Syspar2, \
GainMode, 0.004, 0.08, AdaptMode,\
MinDiff, StatNum, ConfidenceC, TimeC)
* Read the next image in sequence:
read_image(Image3,'xing/xing003')
* Estimate the background:
run_bg_esti(Image3,ForegroundRegion3,BgEstiHandle)
* Display the foreground region:
dev_display(ForegroundRegion3)
* etc
结果
