2013-04-27 01:38:38 -0600 | asked a question | How to Store Histogram Values using SparseMat Calculating and storing the dense histogram matrix for my image processing operations is inefficient. ( there is no many differences on the image's color ) For the sake of efficiency, I want to use a sparse matrix. I could not find any example that stores histogram values on sparse matrix. How can I use a SparseMat for storing histogram values using OpenCV? Please, can you give me a code example or link that I can read? |

2013-02-08 13:19:50 -0600 | asked a question | How to speed up this code implemented OpenCV I need an advice for sample below code that requires lots of time for processing. I am developing project on OpenCV and have code blocks like this ( some of them are pictures ). What should I use for more speed? Like, OpenMP or TBB ( that's new in OpenCV and more complex, maybe some examples more helpful ) or GPU ( implementing entire project ) or Boost library or another I don't know 3rd party libraries. i didn't write multithread on c++ before thanks for helping now sample code snippet: |
