This is a good solution when you work with a dynamically loaded component (e.g. DLL) but not when you just link to the library ...
I am running Tesseract 3.0 built as a library linked to a Mac OS application and this is the leak I am measuring for successive scans: - image with lots of lines: around 400MB - image with 3 or 4 lines: around 40MB - almost blank image: around 20MB I noticed that the leaking allocations are done during the processing continuously (i.e. not right at the start or the end of processing an image) so it seems it's the structures for holding lines and blocks. I just call Init(), SetPageMode(), SetImage() and GetBoxText(). For after each image processing I call End() on my TessBaseAPI class instance and even call delete() on it, for good measure - but to no avail. Would it help if I used lower level Tesseract API returning blocks and page res structures and released them explicitly? It's commonplace to have memory leaks but 400MB seems so high that I am still hoping I am doing something wrong. Thanks!
