Automatic defect segmentation by unsupervised anomaly learning

no code implementations7 Feb 2022 Nati Ofir, Ran Yacobi, Omer Granoviter, Boris Levant, Ore Shtalrid

We train a U-net shape network to segment defects using a dataset of clean background images.

Segmentation

Multispectral image fusion based on super pixel segmentation

1 code implementation21 Dec 2021 Nati Ofir, Jean-Christophe Nebel

This paper focuses on the task of fusing color (RGB) and near-infrared (NIR) images as this the typical RGBT sensors, as in multispectral cameras for detection, fusion, and dehazing.

Multi-scale Processing of Noisy Images using Edge Preservation Losses

1 code implementation26 Mar 2018 Nati Ofir, Yosi Keller

As our experiments show, we achieve high-quality results in the three aspects of faint edge detection, noisy image classification and natural image denoising.

Deep Multi-Spectral Registration Using Invariant Descriptor Learning

no code implementations16 Jan 2018 Nati Ofir, Shai Silberstein, Hila Levi, Dani Rozenbaum, Yosi Keller, Sharon Duvdevani Bar

Our algorithm detects corners by Harris and matches them by a patch-metric learned on top of CIFAR-10 network descriptor.

Photometric Stereo by Hemispherical Metric Embedding

no code implementations25 Jun 2017 Ofer Bartal, Nati Ofir, Yaron Lipman, Ronen Basri

We present a novel embedding method that maps pixels to normals on the unit hemisphere.

On Detection of Faint Edges in Noisy Images

2 code implementations22 Jun 2017 Nati Ofir, Meirav Galun, Sharon Alpert, Achi Brandt, Boaz Nadler, Ronen Basri

A fundamental question for edge detection in noisy images is how faint can an edge be and still be detected.

Edge Detection

Fast Detection of Curved Edges at Low SNR

3 code implementations CVPR 2016 Nati Ofir, Meirav Galun, Boaz Nadler, Ronen Basri

Detecting edges is a fundamental problem in computer vision with many applications, some involving very noisy images.
