Adaptive Image Quantization Using Total Variation Classification

Most perceptual quantization algorithms use some kind of activity measure such as variance in determining the quantization step size for local macroblocks in MPEG coding. In this paper, we use directional total variation as a new kind of activity measure to develop a novel adaptive quantization algorithm. The scheme is contrasted with a method proposed by Puri and Aravind. Simulation result sug...

Adaptive Total Variation Image Deconvolution: Application to Magnetic Resonance Imaging

This paper presents a new approach to image deconvolution (deblurring), under total variation (TV) regularization, which is adaptive in the sense that it doesn’t require the user to specify the value of the regularization parameter. We follow the Bayesian approach of integrating out this parameter, which is achieved by using an approximation of the partition function of the Bayesian interpretat...

Weighted Nonlocal Total Variation in Image Processing

In this paper, a novel weighted nonlocal total variation (WNTV) method is proposed. Compared to the classical nonlocal total variation methods, our method modifies the energy functional to introduce a weight to balance between the labeled sets and unlabeled sets. With extensive numerical examples in semi-supervised clustering, image inpaiting and image colorization, we demonstrate that WNTV pro...

Image Enhancement Using Adaptive Filtering

In this paper, we develop an image enhancement algorithm that modifies the local luminance mean of an image and controls the local contrast as a function of the local luminance mean of the image. The algorithm first separates an image into its lows (low pass filtered form) and highs (high pass filtered form) components. The lows component then controls the amplitude of the highs component to in...

Total Variation Electrocardiogram Filtering

We examine the performance of Total Variation (TV) smoothing for processing of noisy Electrocardiogram (ECG) recorded by an ambulatory device. The TV smoothing is compared with traditionally-used bandpass filtering using ECG with artificially added noise, as well as with real-world noise obtained during physiological monitoring. The fundamental difference between TV smoothing and traditional ba...
