<div dir="ltr">It looks like the setting in that example configuration file are out of date. When we moved to OpenCV 3 we had to restructure how OpenCV feature detectors/descriptors are specified in the config file. It looks like these examples where never updated. I don't have time to update them myself right now, but we should be able to find someone who can do it.<div><br></div><div>--Matt</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Feb 11, 2019 at 1:54 AM renuka ghate <<a href="mailto:renukaghate@gmail.com">renukaghate@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr">
