An optimization algorithm based on the LMPEC algorithm is proposed to rectify the nameplate image to address the problem that overexposure and underexposure of the nameplate image of electrical equipment will make subsequent nameplate recognition difficult. In the network structure. the PS-UNet++ network is based on the sub-pixel convolution upsampling module. and the UNet++ network i... https://parisnaturalfoodes.shop/product-category/pumice-soap/
