6.2.4.2 Bayer Interpolation Method
Basic operation performed by the See3CAM Direct Show Bayer transform filter is demosaicing of
Bayer image received from USB camera. Demosaicing is the process of reconstructing a green
component dominated Bayer image to an equal weighted viewable RGB image. Figure 1
represents the arrangement of pixels information in Bayer image and output of demosaicing
algorithm.

There are various interpolation algorithms that favor speed or favor quality. Based on the
requirement, Bayer Transform filter provides option to choose from the following 3 interpolation
algorithm.
1.
Nearest Neighbor – Fast but poor quality.
2.
Bilinear Interpolation – Better quality than Nearest Neighbor.
3.
Advanced Homogeneity Directed – Good quality but very slow.
The ACC-CX3RDK-5680 Bayer Color camera will use Nearest Neighbor method by default, but
the user can switch to other methods also.
When using the Advanced Homogeneity Directed method, the frame rate will drop depending on
the computer configuration. This is because of the processing overhead of this method.
