Color Image Watermarking Scheme Based on Efficient Preprocessing and Support Vector Machines

A color image watermarking scheme based on hybrid classification method: Particle swarm optimization and k-nearest neighbor algorithm

“…Some of these studies obtaining the watermark utilizing features extracted from the blocks in which watermark is embedded in the spatial domain are implemented by SVM [9,10] and ANN [11], and also obtaining the watermark utilizing features extracted by employing statistical techniques in the frequency domain is implemented by SVM and ANN together [12].…”
