It is known that local filtering-based edge preserving smoothing techniques suffer from halo
artifacts. In this paper, a weighted guided image filter (WGIF) is introduced by incorporating …

In this paper, we introduce an exposure fusion scheme for differently exposed images with
moving objects. The proposed scheme comprises a ghost removal algorithm in a low …

The guided image filter (GIF) and weighted guided image filter (WGIF) are local linear model-
based good edge-preserving filters. However, due to fixed regularization parameter, they …

Image quality is affected by various factors, especially low illumination. We propose an
image color enhancement method to improve the brightness and quality of images. First, we …

Digital image processing helps to achieve good process in various research fields but still
enhancing the degraded content to normal content is concerned area. Image enhancement …

Bilateral filter is perhaps the most popular and simplest edge-preserving local filter.
However, it may produce halos near some edges due to unwanted smoothing of the edges …

During the process of image acquisition, the quality of images will be affected by many
factors, and the most prominent problem is the negative effect of illumination. In order to …

Total variation has proved its effectiveness in solving inverse problems for compressive
sensing. Besides, the nonlocal means filter used as regularization preserves textures well in …

Digital image processing has revolutionized the content perception from physical photo
appearance to digital image appearance by implementing the digitalization. Digital image …

Weighted guided image filter (WGIF) can be used to avoid halo artifacts and to increase
filtering. In this technique, WGIF is put forth for capturing high quality videos which are …
