Violence Detection in Video by Large Scale Multi-Scale Local Binary Pattern Dynamics

  1. 1. 2. The MSLBP dynamics approach• Video stream downsampled at 5Hz• For each image, we generate a M vector of 10240 elements = its Multi-Scale Local Binary Pattern (MSLBP)• We compute the average and variance of dM / dt for each section of 20 seconds• We train a Linear SVM on the resulting 20480 dimensions target : violence• Let the shot estimates = max(prediction on all sections included in the shot)
  2. 2. 3. RESULTS & CONCLUSION Runs on the 3rd movie are misleading due to feature computation errors…Results will be easely improved becausethe model makes the difference betweenfast movements versus violent events, BUT it suffers from desynchronization (few sec)…: P = 0.19 P = 0.50
