Hi,
I have a code like this:
init_ocropus_components();
bytearray inImageGray;
read_image_gray(inImageGray, stdio(argv[1],"r"));
autodel<ISegmentPage> segmenter(make_SegmentPageByRAST());
intarray segmentation;
segmenter->segment(segmentation, inImageGray);
write_png_packed(stdio(argv[2], "w"), segmentation);
RegionExtractor *regions;
regions->setPageColumns(segmentation);
bytearray columnImage;
for(int i=1; i<regions->length()-1;i++) {
regions->extract(columnImage, inImageGray,i,1);
cout << "columns extracted" << endl;
}
when I run this code, I get the error:
*** glibc detected *** /home/haydar/projects/ColumnFinder/build/

*** Program received signal SIGABRT (Aborted) ***
I know that there is a memory leak or something but I don't know how
to debug. I must have made a mistake in the use of RegionExtractor.
Can anyone help me?
Thanks.
