TLDR
This work presents basic image pipeline algorithms and tuning methods from a system point of view and shows how to tune an image pipeline for a particular camera system based on different lenses, camera modules, and sensors.Abstract:
Digital cameras are widely used in many applications, such as digital still cameras, camcorders, camera phones, and video surveillance. The image pipeline plays a key role in digital camera systems by generating a digital color image in real time from raw data captured by a camera sensor. However, tuning an image pipeline for a particular camera system is a challenging task because different lenses, camera modules, and sensors have different characteristics. Moreover, there are no standard image quality metrics and different customers have different preferences for image quality. We present basic image pipeline algorithms and tuning methods from a system point of view.read more

CID2013: A Database for Evaluating No-Reference Image Quality Assessment Algorithms
TL;DR: A new video database is presented: CVD2014-Camera Video Database, which uses real cameras rather than introducing distortions via post-processing, which results in a complex distortion space in regard to the video acquisition process.
Introduction to Color Imaging Science
TL;DR: This book is a comprehensive guide to the scientific and engineering principles of colour imaging that covers the physics of light and colour, how the eye and physical devices capture colour images, how colour is measured and calibrated, and how images are processed.

TL;DR: The accepted air pollutant concentration limits for sensitive artwork are generally at or below a few ppb: this is only ∼1% of the permissible exposure limits for humans as mentioned in this paper.

Demosaicking: color filter array interpolation
TL;DR: The author begins by discussing the image formation process and examines the demosaicking methods in three groups: the first group consists of heuristic approaches, the second group formulates demosaicked as a restoration problem, and the third group is a generalization that uses the spectral filtering model given in Wandell.
