2013-05-27 08:26:58 -0500	commented question	Image Transport Compressed issue for Depth Image - ROS Fuerte Solution: The default compression algorithm is "jpeg" which should be changed to "png" in case of depth image. This can be done by changing the "format" parameter for that topic(/image_transport_type).
2013-05-22 22:43:36 -0500	asked a question	Image Transport Compressed issue for Depth Image - ROS Fuerte Hi, I am using Depth Image for one of my applications, where I need to use compressed image transport for some server/client app. If I use param -> "_image_transport:=raw", everything works fine, but if I use "compressed" instead of "raw", then the depth values that I get are not similar. I am using "/camera/depth/image_raw" topic and converting the image into "16UC1" format using cv_bridge. Then I access the depth values using a Mat and type "ushort". Is there some issue with the format of image that I need to change for accessing the depth values for compressed image transport? Thanks in advance! Sourav
2012-09-04 19:10:49 -0500	commented answer	rgbdslam build error Now there is runtime error, launch is successful, it opens up the window shows the frame, but as soon as I press Enter or Space key it says: Pause toggled to: false...Construction of Node with SURF Features...[rgbdslam-7] process has died [pid 11193, exit code -11]
2012-09-04 19:08:25 -0500	commented answer	rgbdslam build error Thanks, the compilation error was because there was already rgbdslam at some other location, which may had led to some conflicts. I removed all such rgbdslam directories and it compiled successfully, but with warnings related to libopebcv2.3 and libopencv2.4 conflicts.

2012-09-04 17:03:26 -0500	commented answer	rgbdslam build error I had earlier stopped it at 6000 seconds; and then ran it again, with following error: (Edit in previous answer as per rules.)
2012-09-04 01:49:19 -0500	answered a question	rgbdslam build error I tried: rosmake g2o but it gave same error, rosmake --pre-clean rgbdslam did work but now its stuck somewhere as it has already spent 4700 seconds so far compiling it and still compilation is on: [ rosmake ] [ make ] [g2o: 4856.8 sec] [ 1 Active 51/53 Complete ] Any suggestions what I am doing wrong?
