Face detection and recognition mechanisms are widely used in many multimedia and security devices. The concept is called face detection and there are significant numbers of studies into face recognition, particularly for image processing and computer vision. However, there remain significant challenges in the existing systems due to limitations behind algorithms. Viola Jones and Cascade Classifier...
This paper proposes a new integrated system based on a video watermarking algorithm with high imperceptibility, improved security, robust against common image and video processing attacks and geometric attacks. The proposed algorithm is based on the features of a selected best algorithm by Agilandeeswari and Ganesan and its limitations. The advantages of the hybrid transform techniques of Nonsubsampled...
This paper presents a method based on contour let transform for the purpose of art authentication. The sample digital images from the different artist are converted to the gray scale images. The background patches from the gray scale images are extracted. The extracted patches are transformed using Contourelet transform and modeled using Hidden Markov Tree (HMT). The fisher distance information is...
