Novel Multi-Dimensional Spatially-Adaptive Image Recovery Using Spline Interpolation
Hong Cao, Ha H. Nguyen · 2019
A method to increase the resolution of single image sensor digital cameras to the equivalent of three image sensors digital cameras is investigated in this paper. The novelty in the proposed method lies in the development of a mosaic color filter array (CFA) whose structure is capable of receiving full resolution color component signals. This is made possible by using multi-dimensional spatially-adaptive image recovering and exploiting the spatial periodic micro displacement of the light flux against the mosaic CFA itself. Test results obtained with popular images are presented to illustrate the effectiveness of the proposed method.
