Intelligent Detail Enhancement for Exposure Fusion
IEEE Transactions on Multimedia, 2018Multiscale exposure fusion is a fast approach to fuse several differently exposed images captured at the same high dynamic range (HDR) scene into a high-quality low-dynamic range (LDR) image. The fused image is expected to include all details of the input images.

A robust algorithm for exposure fusion
2012 IEEE 11th International Conference on Signal Processing, 2012A still image is usually insufficient to depict a high contrast scene. Exposure fusion can enhance the high dynamic range details of an image. A robust algorithm for multi-exposure images fusion is proposed in this paper. In our algorithm, an overall luminance layer and local details are combined to generate an image that can describe a High Dynamic ...

Multi-exposure Fusion With JPEG Compression Guidance
2018 IEEE Visual Communications and Image Processing (VCIP), 2018Construct a High Dynamic Range (HDR) image is the primary method to solve the information loss caused by insufficient dynamic range of cameras. We propose a technique for fusing a bracketed low dynamic range (LDR) image sequence of varying exposures into an HDR image, skipping the physically-based HDR assembly step.

Alignment-free exposure fusion of image pairs
2014 IEEE International Conference on Image Processing (ICIP), 2014This paper presents an effective fusion technique for an exposure bracketed pair of images, which may contain motion blur from moving objects or hand trembling. Exposure fusion is a technique to represent a high dynamic scene by fusing differently exposed images.

A single algorithm combining exposure and focus fusion
2011 18th IEEE International Conference on Image Processing, 2011In scenes of significantly varying lighting conditions, under and over exposed regions can suffer from a loss of information. Similarly, the presence of spatial depth within a scene can cause some image regions to be out of focus. Several methods of addressing these issues exist, including tone mapping for true high dynamic range representation and ...

Single image brightening via exposure fusion
2016 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2016It is very challenging to capture images via cell phone cameras in low-lighting conditions due to possible motion blur, especially for a high dynamic range (HDR) scene. In this paper, a new single image brightening algorithm is introduced to support capturing an image with a small exposure time and a small ISO value for a low-lighting scene.

Multi-exposure images of wavelet transform fusion
SPIE Proceedings, 2013In many cases, the image acquisition devices have a limited dynamic range, which is lower than one encounter in the real world. The capture image from the camera can not reflect the high dynamic range. According to different exposure time of images in the same scene, it apply the Laplace sharpening the images and enhancing their details, and it use ...

Enhancing image visuality by multi-exposure fusion
Pattern Recognition Letters, 2019Abstract Image visuality enhancement aims at increasing visual quality of a given image to convey more useful information. The key for visuality enhancement is to comprehensively exploit the details of the image scene. However, one (or several) observed image only provides partial information of the scene.

Variational Exposure Fusion with Optimal Local Contrast
2015In this paper, we present a variational method for exposure fusion. In particular, we combine differently exposed images to a single composite that offers optimal exposedness, saturation, and local contrast. To this end, we formulate the output image as a convex combination of the input, and design an energy functional that implements important ...
