Ghost removal in HDRI acquisition
نویسنده
چکیده
This paper presents a fast, robust and completely automatic technique for creating high dynamic range images of non-static scenes. The technique is based on probability maps. These maps are calculated with comparison function from sequences of hand-held photographs. In practice, several basic problems occur when taking an image sequence. First, the camera is moving which causes images to misalign. This results in a blurry HDR image. Secondly, objects are in movement causing ghost artifacts. Finally, the dynamic range of a single image is decreased by sensor noise. Our solution is a GPU based application for compositing HDR images that can handle all aforementioned problems.

Ghost and Noise Removal in Exposure Fusion for High Dynamic Range Imaging
For producing a single high dynamic range image (HDRI), multiple low dynamic range images (LDRIs) are captured with different exposures and combined. In high dynamic range (HDR) imaging, local motion of objects and noise in a set of LDRIs can influence a final HDRI: local motion of objects causes the ghost artifact and LDRIs, especially captured with under-exposure, make the final HDRI noisy. I...
متن کاملGhost-Free High Dynamic Range Imaging
Most high dynamic range image (HDRI) algorithms assume stationary scene for registering multiple images which are taken under different exposure settings. In practice, however, there can be some global or local movements between images caused by either camera or object motions. This situation usually causes ghost artifacts which make the same object appear multiple times in the resultant HDRI. ...
متن کاملRetrieving Extended High Dynamic Range from Digital Negative Image - An Experiment on Architectural Photo Imaging
The paper explores the development of an optimization of method and apparatus for retrieving extended high dynamic range from digital negative image. Architectural photo imaging can benefit from high dynamic range imaging (HDRI) technique for preserving and presenting sufficient luminance in the shadow and highlight clipping image areas. The HDRI technique that requires multiple exposure images...
متن کاملµ-Law Based HDR Coding and Its Error Analysis
In this paper, we propose a coding algorithm for High Dynamic Range Images (HDRI). Our encoder applies a tone mapping model based on scaled μ-Law encoding, followed by a conventional Low Dynamic Range Image (LDRI) encoder. The tone mapping model is designed to minimize the difference between the tone-mapped HDRI and its LDR version. By virtue of the nature of the μ-Law model, not only the quali...
متن کاملSilhouettes Fusion for 3D Shapes Modeling with Ghost Object Removal
In this paper, we investigate a practical framework to compute a 3D shape estimation of multiple objects in real-time from silhouette probability maps in multi-view environments. A popular method called Shape From Silhouette (SFS), computes a 3D shape estimation from binary silhouette masks. This method has several limitations: The acquisition space is limited to the intersection of the camera ...
