Clear Skies Ahead: Towards Real-Time Automatic Sky Replacement in Video

no code implementations6 Mar 2019 Tavi Halperin, Harel Cain, Ofir Bibi, Michael Werman

Digital videos such as those captured by a smartphone often exhibit exposure inconsistencies, a poorly exposed sky, or simply suffer from an uninteresting or plain looking sky.

Neural Separation of Observed and Unobserved Distribution

1 code implementation ICML'19 2018 Tavi Halperin, Ariel Ephrat, Yedid Hoshen

In this work, we introduce a new method---Neural Egg Separation---to tackle the scenario of extracting a signal from an unobserved distribution additively mixed with a signal from an observed distribution.

Neural separation of observed and unobserved distributions

1 code implementation ICLR 2019 Tavi Halperin, Ariel Ephrat, Yedid Hoshen

In this work, we introduce a new method---Neural Egg Separation---to tackle the scenario of extracting a signal from an unobserved distribution additively mixed with a signal from an observed distribution.

Dynamic Temporal Alignment of Speech to Lips

1 code implementation19 Aug 2018 Tavi Halperin, Ariel Ephrat, Shmuel Peleg

This alignment is based on deep audio-visual features, mapping the lips video and the speech signal to a shared representation.

Constrained Lip-synchronization Video Alignment

Seeing Through Noise: Visually Driven Speaker Separation and Enhancement

no code implementations22 Aug 2017 Aviv Gabbay, Ariel Ephrat, Tavi Halperin, Shmuel Peleg

Isolating the voice of a specific person while filtering out other voices or background noises is challenging when video is shot in noisy environments.

Improved Speech Reconstruction from Silent Video

no code implementations1 Aug 2017 Ariel Ephrat, Tavi Halperin, Shmuel Peleg

Speechreading is the task of inferring phonetic information from visually observed articulatory facial movements, and is a notoriously difficult task for humans to perform.

An Epipolar Line from a Single Pixel

no code implementations28 Mar 2017 Tavi Halperin, Michael Werman

In this paper we propose a new method to compute the epipolar geometry from a video stream, by exploiting the following observation: For a pixel p in Image A, all pixels corresponding to p in Image B are on the same epipolar line.

EgoSampling: Wide View Hyperlapse from Egocentric Videos

no code implementations26 Apr 2016 Tavi Halperin, Yair Poleg, Chetan Arora, Shmuel Peleg

However, this accentuates the shake caused by natural head motion in an egocentric video, making the fast forwarded video useless.

Epipolar Geometry Based On Line Similarity

no code implementations17 Apr 2016 Gil Ben-Artzi, Tavi Halperin, Michael Werman, Shmuel Peleg

This paper proposes a similarity measure between lines that indicates whether two lines are corresponding epipolar lines and enables finding epipolar line correspondences as needed for the computation of epipolar geometry.

EgoSampling: Fast-Forward and Stereo for Egocentric Videos

no code implementations CVPR 2015 Yair Poleg, Tavi Halperin, Chetan Arora, Shmuel Peleg

While egocentric cameras like GoPro are gaining popularity, the videos they capture are long, boring, and difficult to watch from start to end.
