Image Processing With Image Resolution Enhancement By Using Stationary And Discrete Wavelet In Decomposition PatternAn image resolution enhancement technique based on the wavelet decomposition and interpolation techniques. Input image is applied with stationary and discrete wavelet transforms separately. The ...
本文展示了双树复小波变换 (Dual-Tree Complex Wavelet Transforms,DTCWT) 在信号、图像和轴承故障诊断方面的应用。 DTCWT 为两个独立的两通道滤波器组,在实际应用用,不能随意选择两棵树中使用的尺度小波滤波器。第一棵树 {h0 ,h1 } 的低通(尺度)和高通(小波)滤波器生成一个尺度函数和小波,另一棵树是由第一...
Biorthogonal wavelet filters have linear phase which is very critical for image processing. Using a biorthogonal wavelet will not introduce visual distortions in the image. An orthogonal transform does not color white noise. If white noise is provided as input to an orthogonal transform, the output...

Since the image colormap is only used for display purposes, some indexed images may need to be preprocessed to achieve the correct results from the wavelet decomposition. In general, color indexed images do not have linear, monotonic colormaps and need to be converted to the appropriate gray-sc...
English: The program is written based on MATLAB R2018b and features a GUI interface (developed in the GUIDE environment). It utilizes wavelet transform for image processing, which includes image fusion, denoising, compression, and image hiding. The program provides sample image materials for testing...
