SVM Tutorials

Currently working on unknown action classification based on the output of SVM classifier for known action classes. Basic idea is how to segregate unknown actions from the known actions given the knowledge that we already have.

Below is a link with tutorial with good SVM tutorials.

Experimental tasks

List of tasks (8/8/2012)
  

• Verify the correctness of implementation on all processes of existing work

• Done usingKTH and Weizmanns action dataset
• Benchmark against VLFeat's BOW using Laptev's HOG-HOF descriptor
• List of different processes involved:
• STIP detection
• Number of interest points
• BOW formation
• Vector quantization
• Histogram binning
• Building of classifier
• ST Correlation & Haralick texture computation

• Computational complexity is to be calculated
• MMI Clustering
• Evaluate performance of K-means against MMI clustering
• Try to use MMI clustering as the primary clustering process

• Verify behaviour of classifier against unknown action datasets as well as action classes
• Inter dataset classification
• Behaviour against unknown action class, abilitiy to distinguish unknown action classes

•  Research on other texture measurement methods which are more recent in comparison to Haralick
