Abstract

In this paper, one experiment teaching case design for photoelectric sensor signal processing is proposed, by using the filtering of contact image sensor (CIS) as a example. The signal with the noise of CIS the scanning output signal will affect the authenticity of the image, so based on the analysis of the CIS output signal noise, the design of two-dimensional wavelet transform for the reconstruction of the image by the CIS output signal of the filter which is based on Xilinx FPGA dsp48 structurally and realized the accelerated calculation through the FIR IPCore, will be introduced in this paper. From the experiment, this algorithm can reduce most of the noise in reconstructed image to ensure reconstructed image can be complete and clear.
