The 2D Hotelling filter - a quantitative noise-reducing principal-component filter for dynamic PET data, with applications in patient dose reduction
BACKGROUND In this paper we apply the principal-component analysis filter (Hotelling filter) to reduce noise from dynamic positron-emission tomography (PET) patient data, for a number of different radio-tracer molecules. We furthermore show how preprocessing images with this filter improves parametric images created from such dynamic sequence.We use zero-mean unit variance normalization, prior ...
متن کاملThe Role of Principal Component Filter Banks in Noise Reduction
The purpose of this paper is to demonstrate the optimality properties of principal component filter-banks for various noise reduction schemes. Optimization of filter-banks (FB’s) for coding gain maximization has been carried out in the literature, and the optimized solutions have been observed to satisfy the principal component property, which has independently been studied. Here we show a stro...
متن کاملA noise reduction filter for full-frame data imaging devices
— This paper describes a method for video sequences denoising that exploits extra-information provided by the image sensor. Fixed Pattern Noise and Temporal Noise are removed by analyzing a series of lines placed at the top of the imager.
متن کاملAdaptive Optimum Notch Filter for Periodic Noise Reduction in Digital Images
Periodic noises are unwished and spurious signals that create repetitive pattern on images and decreased the visual quality. Firstly, this paper investigates various methods for reducing the effects of the periodic noise in digital images. Then an adaptive optimum notch filter is proposed. In the proposed method, the regions of noise frequencies are determined by analyzing the spectral of noisy...
متن کاملCT Filter with In - Band Noise Reduction
In a direct-conversion wireless receiver the baseband filter should be able to handle large blockers, resulting in a very challenging spurious free dynamic range (SFDR) requirement. In particular, the noise added in-band trades off with the linearity required to handle close out-of-band interferers [1]. Since the integrated noise generally is proportional to kT/C, once the noise floor for the f...
