Research on Digital Image Scaling Based on Bicubic Filter Algorithm

As the development of Semiconductors and sensor manufacture technology, to solve the problem of low responsibility in CCD multi-spectral image, in recent years BINNING technique appears on CCD Chip. The analogue binning pixels are simple addition and the part of high frequency information has been lost. In this paper, a new digital pixel binning based on bicubic filtering algorithm is processed. This method can overcome the analog Pixel Binning technology of CCD chip. The digital pixel binning method can preserve high requency information through bicubic filtering algorithm, which can improve the contrast and MTF of the remote sensing image. This algorithm can achieve pixel binning by low computational complexity and also it has the well Real-time Capability for the large-scale remote sensing image.
