چکیده

In this paper, we conduct a series of experiments to evaluate the translation invariant property of a set of discrete wavelet features in a face graph. Using local-area power spectrum estimation based on discrete wavelet transform, we compute a feature vector that possesses both efficient space-frequency structure and translation invariant properties.

Pose Invariant Face Recognition using Hybrid DWT-DCT Frequency Features with Support Vector Machines

Face recognition is a challenging problem and up to date, there is no technique that provides a robust solution to all situations. This paper presents a hybrid approach to pose invariant human face recognition. The proposed scheme is based on a combination of the Discrete Wavelet Transform (DWT) and Discrete Cosine Transform (DCT) analysis on face images. The DWT-DCT domain coefficients are use...

Wavelet Based Watermarking Detection Using Multiresolution Image Registration

Due to the lack of invariant property of discrete wavelet transform (DWT), the DWT based watermarking schemes are relatively vulnerable to the watermarking attacks such as geometric variations (i.e., rotation and translation etc.). To improve the reliability of the DWT based watermark detection, this paper introduces the new multiresolution based image registration method that is used to recove...

RST Resilient Watermarking Scheme Based on DWT-SVD and Scale-Invariant Feature Transform

Abstract: Currently, most digital image watermarking schemes are affected by geometric attacks like rotation, scaling, and translation (RST). In the watermark embedding process, a robust watermarking scheme is proposed against RST attacks. In this paper, three-level discrete wavelet transform (DWT) is applied to the original image. The three-level low frequency sub-band is decomposed by the sin...

Pseudo Zernike Moment-based Multi-frame Super Resolution

The goal of multi-frame Super Resolution (SR) is to fuse multiple Low Resolution (LR) images to produce one High Resolution (HR) image. The major challenge of classic SR approaches is accurate motion estimation between the frames. To handle this challenge, fuzzy motion estimation method has been proposed that replaces value of each pixel using the weighted averaging all its neighboring pixels i...

Robust Zero-watermarking Scheme Using Local Invariant Keypoints

This paper presents a novel zero-watermarking scheme, which is robust to geometric distortions and common signal processes. Zero-watemarking technique is different from traditional digital image watermarking, which constructs watermark from its host image, instead of watermark inserting. We construct watermark from low-frequency coefficients in discrete wavelet transform (DWT) domain, which is ...
