Today, image fusion as one kind of information integrated technology has played an important role in many fields. This paper presents a novel wavelet based technique for image fusion, which is developed by taking into account the physical meaning of the wavelet coefficients. The images to be fused are firstly decomposed into high frequency and low frequency bands by wavelet transform. Then, by ...

This paper retrieves an optical 1–soliton solution to a model that is written as concatenation of the Lakshmanan–Porsezian–Daniel and Sasa–Satsuma equation. The method undetermined coefficients obtains full spectrum solutions. multiplier approach yields conserved densities, which subsequently lead quantities from bright solution.

A litling based I-D Discrete Wavelet Transform (DWT) core is proposed. It is re-configurable for Y 3 and 9/7 filters in JPEG2000. Folded architecture is adopted to reduce the hardware cost and achieve the higher hardware utilization. Multiplication is realized in hard\+ ired multiplier with coefficients represented in canonic signcd-digit (CSD) form. I t is a compact and efficient DWT core for ...

In the field of Image Quality Assessment (IQA), this paper examines a Reduced Reference (RRIQA) measure based on the bi-dimensional empirical mode decomposition. The proposed measure belongs to Natural Scene Statistics (NSS) modeling approaches. First, the reference image is decomposed into Intrinsic Mode Functions (IMF); the authors then use the Generalized Gaussian Density (GGD) to model IMF ...

A novel digital watermarking for image authentication is proposed in this paper. Most previous proposed watermarking algorithms embed sequences of random numbers as watermarks. Here images are taken as watermarks for embedding. In the proposed approach, the host image is decomposed into wavelet coefficients. Local entropies of wavelet coefficients in the low-frequency subband are calculated by ...

A new scheme for the implementation of programmable FIR digital filters with 100% operational efficiency is presented in this paper. The term 100% operational efficiency implies that no zero bits have to be inserted between successive in−put data words in order the filter input to be synchronized with the filter output. Both the input data and the filter out−put are in two’s complement LSB−firs...

In this paper, a high speed reconfigurable FIR filter with multiple taps using accumulator based radix-4 multiplier is proposed. The 3n-bit binary input is converted into three residues using binary to residue number system (RNS) converter and then processed in three FIR sub filters constructed in direct form. The filter structure is implemented with a multiply and accumulate (MAC) architecture...

Abstract. A certain subclass of analytic functions in the open unit disc with negative coefficients is introduced. The new class is defined by means of multiplier transformations. By making use of the familiar concept of neighborhoods of analytic function, the author proves coefficient inequalities, distortion theorems and associated inclusion relations for the (n, δ)-neighborhoods of functions...

We obtain a necessary and sufficient condition for the linear independence of solutions of differential equations for hyperlogarithms. The key fact is that the multiplier (i.e. the factor M in the differential equation dS = MS) has only singularities of first order (Fuchsian-type equations) and this implies that they freely span a space which contains no primitive. We give direct applications w...
