Fast video demosaicking solution for mobile phone imaging applications

This paper introduces a cost-effective video demosaicking solution suitable for mobile phones with video capturing capabilities. The proposed solution is a spatio-temporal demosaicking scheme, which operates over three subsequent frames of the acquired video sequence. To rapidly demosaick the raw, color filter array (CFA), spatiotemporal video data our solution uses multi-stage processing concepts and builds on the principles of refined spectral modeling and self-adaptation to varying spatiotemporal characteristics. The proposed solution accommodates cost-effective considerations inherent in mobile phone imaging and produces a visually pleasing demosaicked video sequence.
