Abstract :
This paper presents a new low-light multi-frame fusion algorithm to get a bright and clear shot even under dark conditions. To this end, using multiple short-exposure images and one proper-exposure blurry image as an input, a new hierarchical block-wise temporal noise filtering is done. Finally, an online image restoration of the denoising result is conducted along with the blurry image input. Test results on real low-light scene show its effectiveness like fast processing speed and satisfactory visual quality.
