Gaussian Harmony: Attaining Fairness in Diffusion-based Face Generation Models

no code implementations21 Dec 2023 Basudha Pal, Arunkumar Kannan, Ram Prabhakar Kathirvel, Alice J. O'Toole, Rama Chellappa

We mitigate the bias by localizing the means of the facial attributes in the latent space of the diffusion model using Gaussian mixture models (GMM).

Recognizing People by Body Shape Using Deep Networks of Images and Words

no code implementations30 May 2023 Blake A. Myers, Lucas Jaggernauth, Thomas M. Metz, Matthew Q. Hill, Veda Nandan Gandi, Carlos D. Castillo, Alice J. O'Toole

Although the non-linguistic model yielded fewer false accepts at all distances, fusion of the linguistic and non-linguistic models decreased false accepts for all, but the UAV images.

Identity masking effectiveness and gesture recognition: Effects of eye enhancement in seeing through the mask

no code implementations20 Jan 2023 Madeline Rachow, Thomas Karnowski, Alice J. O'Toole

We evaluated the effectiveness of identity-masking algorithms based on Canny filters, applied with and without eye enhancement, for interfering with identification and preserving facial actions.

Twin identification over viewpoint change: A deep convolutional neural network surpasses humans

no code implementations12 Jul 2022 Connor J. Parde, Virginia E. Strehle, Vivekjyoti Banerjee, Ying Hu, Jacqueline G. Cavazos, Carlos D. Castillo, Alice J. O'Toole

These findings also contribute to our understanding of DCNN performance for discriminating high-resemblance faces, demonstrate that the DCNN performs at a level at or above humans, and suggest a degree of parity between the features used by humans and the DCNN.

Accuracy comparison across face recognition algorithms: Where are we on measuring race bias?

no code implementations16 Dec 2019 Jacqueline G. Cavazos, P. Jonathon Phillips, Carlos D. Castillo, Alice J. O'Toole

We discuss data driven factors (e. g., image quality, image population statistics, and algorithm architecture), and scenario modeling factors that consider the role of the "user" of the algorithm (e. g., threshold decisions and demographic constraints).

Face recognition assessments used in the study of super-recognisers

no code implementations12 May 2017 Eilidh Noyes, Alice J. O'Toole

These tests have been used commonly in recent years to gauge the skills of perspective 'super-recognisers' with respect to the general population.

Deep Convolutional Neural Network Features and the Original Image

no code implementations6 Nov 2016 Connor J. Parde, Carlos Castillo, Matthew Q. Hill, Y. Ivette Colon, Swami Sankaranarayanan, Jun-Cheng Chen, Alice J. O'Toole

The results show that the DCNN features contain surprisingly accurate information about the yaw and pitch of a face, and about whether the face came from a still image or a video frame.
