- Abstract: Image manipulation on the latent space of the pre-trained StyleGAN can
control the semantic attributes of the generated images. Recently, some studies
have focused on detecting channels with specific properties to directly
manipulate the latent code, which is limited by the entanglement of the latent
space. To detect the attribute-specific channels, we propose a novel detection
method in the context of pre-trained classifiers. We analyse the gradients
layer by layer on the style space. The intensities of the gradients indicate
the channel's responses to specific attributes. The latent style codes of
channels control separate attributes in the layers. We choose channels with
top-$k$ gradients to control specific attributes in the maximum response layer.
We implement single-channel and multi-channel manipulations with a certain
attribute. Our methods can accurately detect relevant channels for a large
number of face attributes. Extensive qualitative and quantitative results
demonstrate that the proposed methods outperform state-of-the-art methods in
generalization and scalability.

Manipulation [57.99007520795998]
We discover attribute-specific control units, which consist of multiple channels of feature maps and modulation styles.
Specifically, we collaboratively manipulate the modulation style channels and feature maps in control units to obtain the semantic and spatial disentangled controls.
We move the modulation style along a specific sparse direction vector and replace the filter-wise styles used to compute the feature maps to manipulate these control units.

Search [30.17338705964925]
A rich set of semantic directions exist in the latent space of Generative Adversarial Networks (GANs)

Generic object detection has been immensely promoted by the development of deep convolutional neural networks.

In this paper, we realize adaptation from a thoroughly different perspective, i.e., channel-wise alignment.

This is accomplished by using an attribute regularization loss which enforces a monotonic relationship between the attribute values and the latent code of the dimension along which the attribute is to be encoded.
