OpenNPD

Project of object detection.

Usage:

  1. Add needed librarys to 3rdpart folder(opencv).

  2. Make:

    cd src; make clean; make RELEASE=1; cd ..
    ;
  3. Detect example:

    sh ./script/test_detect_demo.sh
  4. Training example: Please refer to

    ./script/npd_train_demo.sh

Note:

  1. Thereis a
    npddetect::prescandetect
    function for faster detection with some lose on recall. Additional parameter
    stepR
    refers to pre-scan step size compared to the original scan step size ( float more than 1 ) . The
    thresR
    refers to the threshold to reject the window( float in [0-1] ).

Result:

  • ROC:

  • Speed:

| image size | window size | cores | time (ms) | | :---: | :---: | :---: | :---: | :---: | | 640x480 | 20x20 | 1 | ~50 |

  • ROC for
    npddetect::prescandetect
