FIGURE 6.6: The demosaicking method of Buades et al. [111]. Gray inter-
polation experiment for various decreasing values of the parameter h. Top:
initial image, bi-linear interpolation, median-based interpolation, anisotropic
interpolation. Bottom: result of [111] for decreasing sequences of values for h.
The initial condition is always given by the median. Figure from [111].
demosaicking are intimately related, and treating them simultaneously is ad-
vocated by several works, which argue that [273]:
– Denoising before demosaicking must be applied on the three color chan-
nels independently, thus not working at the full ...
