Provided are an apparatus for performing leveling of a person image and an operating method thereof. The method includes: receiving an original person image; selecting an arbitrary latent vector in a latent space; generating a virtual person image based on the latent vector; optimizing the latent vector such that identity similarity between the original person image and the virtual person image increases; manipulating the optimized latent vector; and generating a levelled person image corresponding to the original person image, by using the manipulated latent vector.

Discloses are weakly supervised semantic segmentation device and method based on pseudo-masks. The device includes a localization map generator configured to generate a plurality of first localization maps by providing an image to a first classifier; a saliency map processor configured to calculate a saliency loss through a saliency map used to identify a boundary line and a co-occurring pixel based on the plurality of first localization maps; a multi-label processor configured to predict a multi-label based on the plurality of first localization maps and calculate a classification loss; and a pseudo-masks generator configured to generate a second classifier obtained by updating the first classifier based on the saliency loss and the classification loss, and generate the pseudo-masks based on a plurality of second localization maps by the second classifier.
