An efficient method for tomographic imaging in nuclear medicine is PET. Higher sensitivity, higher spatial resolution, and more accurate quantification are advantages of PET, in comparison to SPECT.

Abstract: Bused on theory of wavelet transform, images are analyzed. On this basis, image enhancement is analyzed to apply with wavelet transform. Results are analyzed and compared with low-pass ...

Wavelet has added a new feature called equal loudness that makes all frequencies equally loud. This is helpful because, when you lower the volume of your music, low and high frequencies start to dip ...

This study addresses the challenge represented by the application of deep learning models to the prediction of ocean dynamics using datasets over a large region or with high spatial or temporal ...

Mathematical transforms can be a great help in understanding signals. Imaging trying to look at a complex waveform and figuring out the frequency components without the Fourier transform. [Artem ...

Wavelet transform is a very powerful tool in the field of Signal Denoising. It gives far better denoising results as compared to frequency-selective filters. Wavelet transform is a transformation ...

Abstract: In the process of visual positioning, the collected image needs to be processed first. Image denoising and enhancement belong to the preprocessing phase of digital image, which can ...

In an increasingly data-driven world, mathematical tools known as wavelets have become an indispensable way to analyze and understand information. Many researchers receive their data in the form of ...
