Through theoretical analysis and simulation, the quantization errors of optical wavelet filters constructed by different wavelet bases were studied, and the effects of the exchange of the decomposition wavelets with reconstruction wavelets on quantization errors were analyzed. The experimental results show that the quantization errors of different wavelet bases are usually different and the wavelet base of the minimum quantization error in space and frequency domain is 5/3 wavelet after exchanging the decomposition and reconstruction filters. According to the least quantization error criterion of optical wavelet filter in space domain and frequency domain, an optimal wavelet was constructed based on lifting algorithm.
