| 2012-08-08 09:57:31 -0600 | commented question | OpenCV JPEG 12-bit support Changed BITS_IN_JSAMPLE to 12 in jmorecfg.h but OpenCV won't build :-( There's type mismatches in grfmt_jpeg.cpp. OpenCV expects uchar but gets ushort instead. So looks like OpenCV does not take into account the BITS_IN_JSAMPLE macro to configure itself accordingly. Shame. Would it be complete madness to attempt to fix this myself? The type errors seem to be located only in grfmt_jpeg.cpp and don't seem that hard to fix. I am a bit concerned though that any changes in here will cascade to the rest of the OpenCV library. Are there any gurus that know this part of the code? Any advice? |
| 2012-08-08 08:01:10 -0600 | commented question | OpenCV JPEG 12-bit support I shall try this thanks a lot. However, my understanding is that I still need to recompile libjpeg for 12-bit support (as this library is in charge of encoding/decoding jpeg images). I ll have a go and post back. |
| 2012-08-08 07:14:00 -0600 | asked a question | OpenCV JPEG 12-bit support I am working on a project that requires processing grayscale JPEG images with 12-bit depth per pixel. Does OpenCV support 12-bit JPEG images? The 3rd party library 'libjepg' used by OpenCV supports 12-bit JPEG's but needs to be built for 12-bit support. The macro that defines 8/12-bit support is If I change that macro to 12-bit and rebuild OpenCV, am I good to go? Or does this mess up the internals of OpenCV? |
