calcOpticalFlowFarneback with JavaCV
I can't get calcOpticalFlowFarneback to work in javacv.
when I compile it says it needs
required: IplImageArray,IplImageArray,CvArr, double,int,int,int,int,double,int
found: IplImage, IplImage, IplImage,double,int,int,int,int,double,int
but the documentation doesn't mention IplImageArray.
if I do put it into IplImageArray,
IplImage image1_gray = cvCreateImage( cvSize(image1.width(),image1.height()), IPL_DEPTH_8U, 1 );
IplImage image2_gray = cvCreateImage( cvSize(image2.width(),image2.height()), IPL_DEPTH_8U, 1 );
IplImage flow = cvCreateImage( cvSize(image1.width(),image1.height()), IPL_DEPTH_32F, 2 );
cvConvertImage(image1, image1_gray, CV_CVTIMG_FLIP);
cvConvertImage(image2, image2_gray, CV_CVTIMG_FLIP);
IplImageArray image1array = new IplImageArray(image1_gray);
IplImageArray image2array = new IplImageArray(image2_gray);
calcOpticalFlowFarneback(image1_gray, image2_gray, flow, 0.5, 1, 1, 1, 7,
1.5,OPTFLOW_FARNEBACK_GAUSSIAN);
then it crashes with
OpenCV Error: Assertion failed (func != 0) in unknown function, file ..\..\..\src\opencv\modules\core\src\convert.cpp, line 1095
calcOpticalFlowPyrLK works fine.
javacv 2.4.4
java 1.7.0_17
