Abstract

The peculiarities of image generation by a pretrained conditional generative adversarial network on the basis of semantic scene labeling are investigated. Semantic labeling can be inaccurate and can contain defects that result, for example, from transforming the graphic file formats in which it was stored or transmitted. Cases are discussed of image generation based on such incorrect data—with modification of the hue, saturation, and brightness of the colors in the color labels of various classes of objects. It is determined that changing the hue of the label has an especially strong negative effect on image generation and could result in altering the class of the labeled object. Thus, the distribution uniformity of the label color parameters through the color spaces should be taken into account. Additional requirements should be introduced on the accuracy with which the color labels are represented.
