| 2015-03-11 11:23:03 -0600 | commented question | How to create custom descriptor to use with Bag of words? I'm using the "Dense trajectory" algorithm shown here http://lear.inrialpes.fr/people/wang/.... The features are computed one by one, and each one in a single line, with the following format: frameNum mean_x mean_y var_x var_y length scale x_pos y_pos t_pos Trajectory HOG HOF MBHx MBHy You can see more details at "The format of the computed features" paragraph in the above link. I need to create a Mat descriptor with these features. |

| 2015-03-11 10:31:54 -0600 | asked a question | How to create custom descriptor to use with Bag of words? Hi, is it possible to create a custom descriptor from features compiled with own feature extractor (not SIFT,SURF...) to use with a Bag of words and SVM implementation in OpenCV? So how to set up the Mat descriptor? Thanks in advance. |
