Self-Supervised Dynamic Networks for Covariate Shift Robustness

no code implementations6 Jun 2020 Tomer Cohen, Noy Shulman, Hai Morgenstern, Roey Mechrez, Erez Farhan

As supervised learning still dominates most AI applications, test-time performance is often unexpected.

Dynamic-Net: Tuning the Objective Without Re-training for Synthesis Tasks

1 code implementation ICCV 2019 Alon Shoshan, Roey Mechrez, Lihi Zelnik-Manor

Our approach considers an "objective-space" as the space of all linear combinations of two objectives, and the Dynamic-Net is emulating the traversing of this objective-space at test-time, without any further training.

Adversarial Feedback Loop

1 code implementation ICCV 2019 Firas Shama, Roey Mechrez, Alon Shoshan, Lihi Zelnik-Manor

In this paper we propose a novel method that makes an explicit use of the discriminator in test-time, in a feedback manner in order to improve the generator results.

Improving CNN Training using Disentanglement for Liver Lesion Classification in CT

no code implementations1 Nov 2018 Avi Ben-Cohen, Roey Mechrez, Noa Yedidia, Hayit Greenspan

Training data is the key component in designing algorithms for medical image analysis and in many cases it is the main bottleneck in achieving good results.

Maintaining Natural Image Statistics with the Contextual Loss

3 code implementations13 Mar 2018 Roey Mechrez, Itamar Talmi, Firas Shama, Lihi Zelnik-Manor

Maintaining natural image statistics is a crucial factor in restoration and generation of realistic looking images.

The Contextual Loss for Image Transformation with Non-Aligned Data

3 code implementations ECCV 2018 Roey Mechrez, Itamar Talmi, Lihi Zelnik-Manor

Feed-forward CNNs trained for image transformation problems rely on loss functions that measure the similarity between the generated image and a target image.

Photorealistic Style Transfer with Screened Poisson Equation

1 code implementation28 Sep 2017 Roey Mechrez, Eli Shechtman, Lihi Zelnik-Manor

Recent work has shown impressive success in transferring painterly style to images.

Template Matching with Deformable Diversity Similarity

1 code implementation CVPR 2017 Itamar Talmi, Roey Mechrez, Lihi Zelnik-Manor

We propose a novel measure for template matching named Deformable Diversity Similarity -- based on the diversity of feature matches between a target image window and the template.

Saliency Driven Image Manipulation

1 code implementation7 Dec 2016 Roey Mechrez, Eli Shechtman, Lihi Zelnik-Manor

Have you ever taken a picture only to find out that an unimportant background object ended up being overly salient?
