give_bg_esti — 返回估计的背景图像。
give_bg_esti( : BackgroundImage : BgEstiHandle : )
give_bg_esti returns the estimated background image of
the current BgEsti data set. The background image has the same type
and size as the initialization image passed in
create_bg_esti。
BackgroundImage (输出对象) image → object (byte / real)
Estimated background image of the current data set.
BgEstiHandle (输入控制) bg_estimation → (handle)
ID of the BgEsti data set.
* 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)
* Give the background image from the aktive dataset:
give_bg_esti(BgImage,BgEstiHandle)
* Display the background image:
dev_display(BgImage)
give_bg_esti 在所有参数正确时返回 2 ( H_MSG_TRUE )。
