Embodiment 1
[0077] figure 1 It is a flow chart of the infrared image segmentation method of power system equipment based on wavelet analysis, as shown in the figure: the infrared image segmentation method of power system equipment based on wavelet analysis provided by the present invention includes the following steps:
[0078] S1: Acquire infrared images of electrical equipment;
[0079] S2: Using wavelet transform to eliminate the mixed noise of the infrared image to obtain a denoised image;
[0080] The continuous wavelet transform contains a lot of redundant information, which is not conducive to the analysis and processing of the signal. Continuous wavelet basis functions The discretization of scale factor a and translation factor b in can obtain discrete wavelet transform WTf(a,b), thereby reducing the redundancy of wavelet transform coefficients. In discretization, the scale factor a and the translation factor b are usually discretized according to the power series, that is, ta...
