Color filling model training method and device, color filling method and device and electronic equipment

The invention provides a color filling model training method and device, a color filling method and device and electronic equipment, and relates to the technical field of computers, in particular to the field of cloud computing. The training method comprises the following steps: determining a training sample corresponding to a color filling model; constructing a generator and a discriminator corresponding to the color filling model; determining a target discriminator corresponding to the current discrimination parameter of the discriminator; based on the target discriminator, taking a filling image obtained by carrying out color filling on the grayscale image by the generator and a color image as a training target, and training to obtain a target generator corresponding to the target generation parameter, based on the target generator, taking the identification result of the discriminator on the filling image generated by the target generator meeting the identification condition as a training target, and trai
