Image processing is simply a processing of images or digital images in which processing is a collection of number of steps like denoising, segmentation, compression, representation and recognition. This paper will introduce basic concept of wavelet transform and use of wavelet transform in image ...
The Application of Wavelet Transform in Digital Image Processing The edge is the most important high-frequency information of a digital image. The traditional filter eliminates the noise effectively. But it will make the... X Zhu - International Conference on Multimedia & Information Technology 被引...

The DCT is an general orthogonal transformation for digital signal/image processing that can be used for high-compression applications, good information integration ability, and small bit error rate. It is a Fourier-related transform similar to the discrete Fourier transform. The DCT turns over the...

The spectral analysis of signals is currently either dominated by the speed–accuracy trade-off or ignores a signal’s often non-stationary character. Here we introduce an open-source algorithm to calculate the fast continuous wavelet transform (fCWT). T
