error C2039:? 'foreground_regions' ?: is not a member of? 'CvFGDStatModel'

error C2039: 'foreground_regions' : is not a member of? 'CvFGDStatModel'

error C2039: 'foreground_regions' : is not a member of? 'CvGaussBGModel'

在網(wǎng)上搜到的解決方法都是這樣寫(xiě)的：

在cvaux.h文件中，

搜索關(guān)鍵字foreground_regions，

CvMemStorage* storage; /*storage for 揻oreground_regions ?/ ?\
CvSeq* foreground_regions /*foreground object contours*/

改為如下形式：

CvMemStorage* storage; /*storage for foreground_regions */ ?\
CvSeq* foreground_regions /*foreground object contours*/

具體原因解釋如下：首先f(wàn)oreground_regions 定義在這個(gè)宏里面：

#define CV_BG_STAT_MODEL_FIELDS()?????????????????????????????????????????????????? \
??? int???????????? type; /*type of BG model*/????????????????????????????????????? \
??? CvReleaseBGStatModel release;?????????????????????????????????????????????????? \
??? CvUpdateBGStatModel update;???????????????????????????????????????????????????? \
??? IplImage*?????? background;?? /*8UC3 reference background image*/?????????????? \
??? IplImage*?????? foreground;?? /*8UC1 foreground image*/???????????????????????? \
??? IplImage**????? layers;?????? /*8UC3 reference background image, can be null */ \
??? int???????????? layer_count;? /* can be zero */???????????????????????????????? \
??? CvMemStorage*?? storage;????? /*storage for 揻oreground_regions?*/????????????? \
??? CvSeq*????????? foreground_regions /*foreground object contours*/

“\”在這里代表續(xù)行的意思。并且注意前面定義的變量后面都有“；”號(hào)，而foreground_regions沒(méi)有，因?yàn)樗沁@個(gè)定義的最后一項(xiàng)，因?yàn)楹甓x末尾是不加‘；’號(hào)的。

另外要注意的是，千萬(wàn)不要在修改最后兩行時(shí)寫(xiě)成這個(gè)樣子：???

?CvMemStorage*?? storage;????? /*storage for 揻oreground_regions?*/????????????? \

??? CvSeq*????????? foreground_regions /*foreground object contours*/

即不能放入空行，因?yàn)檫@樣一來(lái)foreground_regions就不屬于宏定義中的一份了。而 'CvFGDStatModel' 和 'CvGaussBGModel' 中均包含了改宏，所以錯(cuò)誤會(huì)照舊的。偶剛開(kāi)始就犯了這個(gè)錯(cuò)誤，還以為是各位高手犯錯(cuò)誤了呢。呵呵
