In this paper an image resolution and contrast enhancement technique for Additive White Gaussian Noise (AWGN) removal is verified aiming high resolution and contrast image output. In image resolution enhancement, the main loss is on its high frequency components (i.e., edges), which is due to the smoothing caused by interpolation. In order to increase the quality of the super resolved image, pr...

We propose a method for accelerating the matching and learning processes of the eigenspace method for rotation invariant template matching (RITM). To achieve efficient matching using eigenimages, it is necessary to learn 2D-Fourier transform of eigenimages before matching. Little attentions has been paid to speeding up the learning process, which is important for applications in which a templat...

This article proposes an anti-fake QR codes watermarking algorithm based on the DWT and SVD, aiming at the security problem of QR code in the actual application. Firstly, this paper analyses the advantage of QR code as well as its problems. Secondly, the principle of the chaos encryption and discrete wavelet transform are introduced in detail. Then, we design a new watermarking barcode by the c...

In this paper, we propose a novel watermarking based on the spatial q-log domain. After decomposing the RGB information of the cover image, we apply the q-log transform to obtain the q-log domain frequency. We embed the watermark into the low-frequency of q-SVD domain in order to achieve the robustness of watermark. We choose in our method the Quantization Index Modulation (QIM) based watermark...

This study proposes a blind watermarking algorithm based on Double Haar Wavelet Transform (DHWT) for copyright protection of digital images. Watermark embedding is performed in wavelet transform domain. DHWT is applied to the original cover image and binary watermark. Singular value decomposition (SVD) is applied on selected subband of cover image and binary watermark. Eigen values of selected ...

This paper presents a robust and secure watermarking technique for digital image. To implement the technique, Discrete Wavelet Transform (DWT) is applied on cover image. Further on Low-Low (LL) sub-band of DWT, Discrete Cosine Transform (DCT) is applied which is followed by Singular Value Decomposition (SVD). To introduce the secure watermarking, watermark is secured using Arnold Transformation...

other areas. However, the spectral properties of the Laplace transform tend to complicate its numerical treatment; therefore, the closely related “truncated” Laplace transforms are often used in applications. In this dissertation, we construct efficient algorithms for the evaluation of the singular value decomposition (SVD) of such operators. The approach of this dissertation is somewhat simila...

A novel saliency detection method for maritime search and rescue using singular value decomposition to the amplitude spectrum is proposed. Color and intensity features of images are extracted and amplitude spectrums of them are obtained by Fourier transform. Singular value decomposition (SVD) is conducted on the amplitude spectrums and the saliency maps are defined as the inverse Fourier transf...
