Abstract

AbstractThis paper presents an efficient, robust and blind approach to detect watermarks embedded in spatial and frequency domains of images. Spatial and transform domain energy features are extracted from the images using Tree Structured Wavelet Transform. An efficient classifier, Totalboost is used to classify the images as watermarked or unwatermarked. In addition to this, the proposed detector can be able to detect watermarks even after various image processing and signal processing attacks. Simulation results show the effectiveness of the proposed scheme in terms of specificity, sensitivity and accuracy. Comparison with state-of-the-art schemes demonstrate the efficiency of the proposed scheme.KeywordsTree Structured Wavelet TransformTotalboostwatermark detectorrobustblind
