2013-12-16 06:45:37 -0600 | asked a question | Speed of cv::linemod with SSE3 Hi, I have recently installed Intel IPP and re-build opencv with SSE and IPP. I am trying to run cv::linemod, which is claimed to run at ~120ms for matching 3000 templates. I have checked that it is making the SSE calls, but still cv::linemod runs at ~4s for ~700 templates. Do you know if the opencv version is able to attain the speed shown in the publication by Hinterstoisser et al. ? |

2012-12-12 06:27:43 -0600 | asked a question | How to visualize a depth image Hi, I am using a dataset in which it has images where each pixel is a 16 bit unsigned int storing the depth value of that pixel in mm. I am trying to visualize this as a greyscale depth image by doing the following: However, it is only showing two colours this is because all of the values are close together i.e. in the range of 150-175 + the small values which show up black (see below).
Is there a way to normalize this data such that it will show various grey levels to highlight these small depth differences? |
