Evaluation of the impact of lossy compression on event camera-based computer vision tasks
Touradj Ebrahimi, Davi Nachtigall Lazzarotto, Bowen Huang
In the field of image acquisition, Dynamic Vision Sensors (DVS) present an innovative methodology, capturing only the variations in pixel brightness instead of absolute values and thereby revealing unique features. Given that the primary deployment of DVS ...
2023Latent Space Slicing for Enhanced Entropy Modeling in Learning-Based Point Cloud Geometry Compression
The growing adoption of point clouds as an imaging modality has stimulated the search for efficient solutions for compression. Learning-based algorithms have been reporting increasingly better performance and are drawing the attention from the research com ...
IEEE2022High-Throughput Lossy-to-Lossless 3D Image Compression
Gilles Fourestey, Félix Schmidt
The rapid increase in medical and biomedical image acquisition rates has opened up new avenues for image analysis, but has also introduced formidable challenges. This is evident, for example, in selective plane illumination microscopy where acquisition rat ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021(Geometry Aware) Deep Learning-based Omnidirectional Image Compression
Omnidirectional images are the spherical visual signals that provide a wide, 360◦, view of a scene from a specific position. Such images are becoming increasingly popular in fields like virtual reality and robotics. Compared to conventional 2D images, the ...
2020On the inference speed and video-compression robustness of DeepLabCut
Pose estimation is crucial for many applications in neuroscience, biomechanics, genetics and beyond. We recently presented a highly efficient method for markerless pose estimation based on transfer learning with deep neural networks called DeepLabCut. Curr ...
Animal Behavior and Cognition2018Audiovisual focus of attention and its application to Ultra High Definition video compression
Touradj Ebrahimi, Martin Rerabek, Jong Seok Lee, Hiromi Nemoto
Using Focus of Attention (FoA) as a perceptual process in image and video compression belongs to well-known approaches to increase coding efficiency. It has been shown that foveated coding, when compression quality varies across the image according to regi ...
SPIE2014Data Compression via Logic Synthesis
Giovanni De Micheli, Andreas Peter Burg, Pierre-Emmanuel Julien Marc Gaillardon, Luca Gaetano Amarù
Nowadays, most software and hardware applications are committed to reduce the footprint and resource usage of data. In this general context, lossless data compression is a beneficial technique that encodes information using fewer (or at most equal number o ...
2014Real-time, high-speed video decompression using a frame- and event-based DAVIS sensor
Dynamic and active pixel vision sensors (DAVISs) are a new type of sensor that combine a frame-based intensity readout with an event-based temporal contrast readout. This paper demonstrates that these sensors inherently perform high-speed, video compressio ...
IEEE2014Subjective evaluation of HEVC intra coding for still image compression
Touradj Ebrahimi, Philippe Hanhart, Martin Rerabek
High Efficiency Video Coding (HEVC) demonstrates a significant improvement in compression efficiency compared to H.264/MPEG-4 AVC, especially for video with resolution beyond HD, such as 4K UHDTV. One advantage of HEVC is the improved intra coding of video ...
2013Evaluation of Side Information Effectiveness in Distributed Video Coding
The rate-distortion performance of a distributed video coding system strongly depends on the characteristics of the side information. One could naively think that the best side information is the one with the largest PSNR with respect to the original corre ...
