Principal Component Analysis-Based Denoising of Color Filter Array Images

ByRastislav Lukac, Lei Zhang

In the last decade, advances in hardware and software technology have allowed for massive replacement of conventional film cameras with their digital successors. This reflects the fact that capturing and developing photos using chemical and mechanical processes cannot provide users with the conveniences of digital cameras which record, store and manipulate photographs electronically using image sensors and built-in computers. The ability to display an image immediately after it is recorded, to store thousands of images on a small memory device and delete them from this device in order to allow its further re-use, to edit captured visual data, and to record images and video with sound makes digital cameras very attractive consumer electronic products.
