Feature Vector-Based Nude Picture Detection

  • To overcome the shortcomings in the existing nude picture filtering systems and image recognition techniques,a feature vector-based nude picture detection algorithm was proposed.In the algorithm,chrominance value of the YIQ color coordinate and hue value of the YUV color coordinate were taken to build the skin color model,and the SSD(sum of square difference)on a 5×5 pixel window is used as the skin texture model.Then features representing the number and proportion of skin areas are extracted from skin mask images and are consequently inputted into an SVM(support vector machine).The experimental results on databases containing 457 nude pictures and 1 101 non-nude pictures show that the proposed algorithm averagely achieves 89.3% in detection accuracy,85.8% in retrieval rate,and 4.4% in error rate.
