This 10 channels are relatively simple to extract mainly by sobel derivatives (cv::sobel).
Yes, the implementation is mainly based on Opencv.
I am using this model param int modelRows = 88;
int modelCols =modelRows/4;
Init features are randomly generated. This is funny part. In some cases program hold 5GB is Ram memory and can cause shutdown of my PC. I cant find why. :)
Now, I am trying different approach of weak feature selectors by AdaBoost, GentleBoost, WaldBoost .
This is only personal research.
In our applications.
Waldboost on Haar + LBP features + Kalman are fast and good enough for me.
I know that Opencv Contrib module has ICF ACF feature extractor and Detector learned by waldboost. After some testing i try to implement my own version and this is the first results.
Adaboost ACF learning details
- I am using Adaboost 1000 weak classifier,
- Ped dataset is my own. 10 000 positive samples. I am working on this dataset time to time for more than 2 years.
- 8 000 Neg samples are generated randomly from my Travel pictures :)
Yes first results after 6 months.
Aggregate channel features first results
In this example is used Town Center Dataset only for demonstration. I can not find any condition of usage on this page. http://www.robots.ox.ac.uk Town Centre Dataset
