Nowadays, smartphone cameras capture bursts of raw photographs whenever the trigger is pressed. These photos are then fused to produce a single picture with higher quality. This paper details implementation method 'Handheld Multi-Frame Super-Resolution algorithm' by Wronski et al. (used in Google Pixel 3 camera), which performs simultaneously multi-image super-resolution demosaicking and denois...

Demosaicking and denoising are among the most crucial steps of modern digital camera pipelines. Meanwhile, joint image denoisingdemosaicking is a highly ill-posed inverse problem where at-least twothirds of the information are missing and the rest are corrupted by noise. This poses a great challenge in obtaining meaningful reconstructions and a special care for the efficient treatment of the pr...

Given a natural image from the single sensor, the key task is to properly reconstruct the full color image. This paper presents an effectively demosaicking algorithm based on fully directional estimation using Bayer color filter array pattern. The proposed method smoothly keeps access to current reconstruction implementations, and outperforms the horizontal and vertical estimating approaches in...

t: Digital color cameras use a single sensor equipped with a color filter array (CFA) to capture scenes in color. Since each sensor cell can record only one color value, the other two missing components at each position need to be interpolated. The color interpolation process is usually called color demosaicking (CDM). The quality of demosaicked images is degraded due to the sensor noise introd...
