Hi I am new to image processing field. My project is to classify the objects in an image/Video. The input is an image/video from surveillance camera. I should classify the objects into three classes. 1) Humans 2) Animals 3) Others (cars). We can consider a fixed background.

Can any one suggest any proven algorithms or papers or opensource code for this purpose? offcourse googling is obvious solution but always an experienced eye is always helpful!

Two approaches are possible:

1 - Use of Bag of Words. Usually have four steps:

  1. Get the feature points from training data;
  2. Create a vocabulary from the features;
  3. Train (using SVM for example);
  4. Test in a image (not in training examples).

    There is a example here and in opencv/samples/cpp/bagofwords.cpp

2 - Use of a latent svm detector. The explanation is here. Have a running example of detection/categorization in opencv/samples/cpp/latentsvmdetector.cpp. You also need the opencv_extra/testdata/cv/latentsvm to properly test it. However I don't know how to make the training of new models in OpenCV.
