【matlab】 ex02 DL : 0: 此程序给出信号的多分辨率分析（Multiresolution Analysis），即信号的多分辨率分解（Multiresolution Decomposition）方法及应用。该程序是一个多抽样率系统（Multirate System）举例，用M个的滤波器，将信号的频谱等分成M部分，使所得抽样频率降为1/M，然后再依据它们的“重要性”给一不同的bit数，那么所传输的bit流必然会进一步下降，起到压缩带宽的作用。-This program gives the signal of the multi-resolution analysis (Multiresolution Analysis), the multi-resolution signal decomposition (Multiresolution Decomposition) method and its application. The program is a multirate rate system (Multirate System) example, with M a filter, the signal' s frequency spectrum is divided into M parts, the proceeds of sampling frequency reduced to 1/M, then according to their " importance" to the bit of a different number, then the transmitted bit stream is bound to decline further, to play the role of bandwidth compression.

【Wavelet】 jnd-using-wavelets DL : 0: In this paper, we propose a new perceptual model for balanced multiwavelet (BMW) transforms. The latter transform achieves simultaneous orthogonality and symmetry without requiring any input prefiltering. The proposed model is derived using multiresolution domain extensions of Chou’s model.

【matlab】 czf_blurcue DL : 0: In this paper, a multimodal image fusion algorithm based on multiresolution transform and particle swarm optimization (PSO) is proposed. Firstly, the source images are decomposed into low-frequency coefficients and high-frequency coefficients by the dual-tree complex wavelet transform (DTCWT). Then, the high-frequency coefficients are fused by the maximum selection fusion rule. The low-frequency coefficients are fused by weighted average method based on regions, and the weights are estimated by the PSO to gain optimal fused images. Finally, the fused image is reconstructed by the inverse DTCWT. The experiments demonstrate that the proposed image fusion method can illustrate better performance than the methods based on the DTCWT, the support value transform (SVT), and the nonsubsampled contourlet transform (NSCT).

【Wavelet】 An-improved-Hilbert-Huang-method-for-analysis-of- DL : 0: The Hilbert–Huang method is presented with modifications, for time-frequency analysis of distorted power quality signals. The empirical mode decomposition (EMD) is enhanced with masking signals based on fast Fourier transform (FFT), for separating frequencies that lie within an octave. Further, the instantaneous frequency and amplitude of the constituent modes obtained by Hilbert spectral analysis are improved by demodulation. The method shows promising time-frequency-magnitude localization capabilities for distorted power quality signals. The performance of the new technique is compared with that of another multiresolution analysis tool, the S-transform—a phase corrected wavelet transform. Analysis on actual measurements of transformer inrush current from an existing laboratory setup is used to demonstrate this technique.
