Wavelet transform is a one of the most powerful concept used in image processing. Wavelet transform can divide a given function into different scale components and can find out frequency information without losing temporal information. Wavelet Transform is more suitable technique as compared to fourier...

The wavelet transform appears to be an efficient tool for image compression.Many works propose an implementation of the pyramid algorithm with some improvement to reduce its treatment time or to increase its performances. However, the pyramid algorithm remains silicon area costly, essentially because of...

Image Processingwavelet transform and fast wavelet transformIn general, image compression reduces the number bits required to represent an image. The main significance of image compression is that the quality of the image is preserved. This in turn increases the storage space and thereby the volume ...
3.1 Discrete Wavelet Transform The wavelet transformation is a mathematical approach which can simultaneously represent an image in both the time domain and the frequency domain [40]. A wavelet transform allocates the signal decomposition in narrow frequency bands. The DWT is a fast and simple trans...
