Angular‐flexible network for light field image super‐resolution
Light field (LF) cameras capture scenes from multiple views and provide additional angular information for image super‐resolution (SR). Existing CNN‐based LF image SR methods commonly develop specific models for different angular resolutions.

An adaptive level set method based on joint estimation dealing with intensity inhomogeneity
Automatic object segmentation has been a challenging task due to intensity inhomogeneity. The traditional way is to eliminate the intensity inhomogeneity, which causes the object to lose useful intensity information. The authors propose an adaptive level

Weakly supervised salient object detection via double object proposals guidance
The weakly supervised methods for salient object detection are attractive, since they greatly release the burden of annotating time‐consuming pixel‐wise masks.

Time-sequential Pipelined Imaging with Wavefront Coding and Super Resolution [PDF]
Wavefront coding has long offered the prospect of mitigating optical aberrations and extended depth of field, but image quality and noise performance are inevitably reduced. We report on progress in the use of agile encoding and pipelined fusion of image

Fusion‐based simultaneous estimation of reflectance and illumination for low‐light image enhancement
Low‐light image enhancement is a challenging field in image processing. Retinex‐based methods perform well for low‐light images. However, reflectance and illumination estimation is an ill‐posed problem.

Infrared imaging enhancement through local window‐based saliency extraction with spatial weight
Infrared image enhancement is an effective way to solve contrast reduction or details degradation in infrared imagery. An infrared enhancement approach based on local saliency extraction is proposed here. First, saliency maps are extracted within a local
