Multi-Camera Platform for Panoramic Real-Time HDR Video Construction and Rendering

Yusuf Leblebici, Vladan Popovic, Kerem Seyid, Ömer Cogal, Eliéva Arlette Pignat

High dynamic range (HDR) images are usually obtained by capturing several images of the scene at different exposures. Previous HDR video techniques adopted the same principle by stacking HDR frames in time domain. We designed a new multi-camera platform wh ...

Hardware Implementation and Applications of High Performance Multiple Camera Architectures

Kerem Seyid

Advancements in imaging technology made commercially available cameras cheaper, easily accessible with higher resolution than ever and with complex image capturing features. Today, it is estimated that more than one billion cameras sold every year. However ...

Block Matching Based Real-Time Optical Flow Hardware Implementation

Yusuf Leblebici, Kerem Seyid, Raffaele Capoccia, Andrea Richaud

Optical flow calculation algorithms are hard to implement on hardware level in real-time due to their complexity and high computational load. In this work, we present a novel hierarchical block matching based optical flow algorithm. The algorithm estimates ...

Hardware implementation of real-time multiple frame super-resolution

Yusuf Leblebici, Kerem Seyid, Sébastien Emmanuel Blanc

Super-resolution reconstruction is a method for reconstructing higher resolution images from a set of low resolution observations. The sub-pixel differences among different observations of the same scene allow to create higher resolution images with better ...

A Real-time Multi-aperture Omnidirectional Visual Sensor Based on Interconnected Network of Smart Cameras

Alexandre Schmid, Yusuf Leblebici, Vladan Popovic, Hossein Afshari, Abdulkadir Akin, Kerem Seyid, Ömer Cogal

Centralized and multi-level implementations of the Panoptic omnidirectional multiaperture visual system were previously presented by the authors, relying on transmission of all camera outputs to a single central processing node for omnidirectional image an ...

Real-Time Omnidirectional Imaging System with Interconnected Network of Cameras

Alexandre Schmid, Yusuf Leblebici, Vladan Popovic, Hossein Afshari, Kerem Seyid

The Panoptic camera is an omnidirectional multi-aperture visual system which is realized by mounting multiple imaging sensors on a hemispherical frame. In this chapter, we will present a novel distributed and parallel implementation of the real-time omnidi ...

Image Blending in a High Frame Rate FPGA-based Multi-Camera System

Alexandre Schmid, Yusuf Leblebici, Vladan Popovic, Hossein Afshari, Abdulkadir Akin, Kerem Seyid, Ömer Cogal

Panoptic is a custom spherical light field camera used as a polydioptric system where imagers are distributed over a hemispherical surface, each having its own vision of the surroundings and a distinct focal plane. The spherical light field camera records ...
