For digital photographs of astronomical objects, where exposure times are usually long and ISO settings high, the so-called dark-current is a significant source of noise. Dark-current refers to thermally generated electrons and is therefore present even in the absence of light. This paper presents a novel approach for denoising astronomical images that have been corrupted by dark-current noise. Our...
The paper is reviewing the new trends of the image sensing, the Super CCDs and the Backlit CMOS. One proposes a new HDR fuzzy-interpolative algorithm that can extend the dynamic range of a still Backlit CMOS image in the Super CCD SR manner: the fusion of two images, the first one with a normal exposure and the other underexposed.
Due to steady advancements in semiconductor technology, greatly-enhanced memory capacity and high-speed data processing are now available, creating many evolving types of audio and video electronic products. The digital camera represents this trend well, where image sensor evolution has been responsible for enabling strong market growth. CCD image sensors have contributed to the miniaturization of...
