Variational Anisotropic Gradient-Domain Image Processing [PDF]
Gradient-domain image processing is a technique where, instead of operating directly on the image pixel values, the gradient of the image is computed and processed. The resulting image is obtained by reintegrating the processed gradient. This is normally

Research on Image Dehazing Based on Dark Channel Prior and Variational Regularization [PDF]
The existing foggy image processing methods can achieve good dehazing effect, but some details are often lost, and noise amplification is easy to occur in the noisy areas.In order to solve these problems, a new variational dehazing model, H-TVBH, is ...

Impact of process variations on computers used for image processing [PDF]
Manufacturing process variations (PV) of transistors in the deep-submicron regime present the single biggest design challenge for large die size VLSI circuits such as processor arrays, GPUs, and FPGAs. However, there are a few applications in signal processing, such as image processing, and speech processing, where errors in computation by the ...

Weighted nonlocal total variation in image processing [PDF]
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.

Colour image segmentation based on a convex K‐means approach
Image segmentation is a fundamental and challenging task in image processing and computer vision. The colour image segmentation is attracting more attention as the colour image provides more information than the grey image. A variational model based on a
