## [Paper](https://arxiv.org/abs/2305.05925) | [Video: Youtube](https://www.youtube.com/watch?v=xzrHNA97wls) | [Video: Bilibili](https://www.bilibili.com/video/BV1qL411X7hc/?share_source=copy_web&vd_source=2483c9488f1bd3f3478cf69bfca4d49e)
Motion deblurring is a critical ill-posed problem that is important in many vision-based robotics applications. The recently proposed event-based double integral (EDI) provides a theoretical framework for solving the deblurring problem with the event camera and generating clear images at high frame-rate. However, the original EDI is mainly designed for offline computation and does not support real-time requirement in many robotics applications. In this paper, we propose the fast EDI, an efficient implementation of EDI that can achieve real-time online computation on single-core CPU devices, which is common for physical robotic platforms used in practice. In experiments, our method can handle event rates at as high as 13 million event per second in a wide variety of challenging lighting conditions. Its benefit has been demonstrated on multiple downstream real-time applications, including localization, visual tag detection, and feature matching.
## Understanding the hardware bias of event camera
[Tutorial of the bias](https://gitlab.com/inivation/inivation-docs/blob/master/Advanced configurations/User_guide_-_Biasing.md)
## Checking the hardware bias using the jAER
One can use the jAER project to get a roughly estimated contrast from the bias currents that are estimated to be generated by the on-chip bias generator bias current ratios:[jAER homepage](https://github.com/SensorsINI/jaer)
Discussion regarding the bias estimation:[discussion](https://groups.google.com/g/davis-users/c/68gp0zxTMUk/m/SpweyJKrDgAJ)
and the physical model that build to estimate the threshold:[Paper](https://ieeexplore.ieee.org/document/7962235/)
## Usage
Test env:
```
ubuntu 18.04
dv-runtime 1.6.1
dv-gui 1.6.0
```
1. download the DV and install it following the tutorial [DV install guide](https://inivation.gitlab.io/dv/dv-docs/docs/getting-started.html)
2. download the fast EDI code
```
git clone https://github.com/eleboss/fast_EDI
```
3. compile the fast EDI module
```
cd ./dv-module/fast-edi
cmake ./
make
```
then you will see the `fedi_FEDI.so`, this is the file you need to add to the dv-gui.
4. configure the DV-GUI search path
```
dv-gui
```
find the `structure - add modules - modify module search path - add path` (this path leads to `fedi_FEDI.so`, for me is `/home/eleboss/Documents/fast_EDI/dv-module/fast-edi`). Then you can add the fast edi modules to the dv-gui and wires it in this way:
5. download the test data [dataset](www.google.com), and play it.
Performance tips: You can tune the contrast or use the jAER to estimate, or use EDI to optimize an accurate contrast.

Colleges and universities cannot ignore the increasingly diverse student population in their classrooms, and how a focus on equity, diversity, and inclusion across disciplines trains students in the intercultural awareness they will need in competitive job markets. Yet while faculty may be aware of a need to understand EDI goals in relationship to their disciplines, and institutions may support EDI in theory, the onus of pedagogical training in EDI often falls on individual faculty. This book was written by faculty and administrators for educators who value the goals of EDI, and seek an intellectual community to help them develop their practice. Important to this book is an honest discussion of common challenges faculty may face when they engage in this difficult work, and effective strategies for addressing those challenges. The chapters are grouped according to six different themes: respect for divergent learning styles; inclusion and exclusion; technology and social action; affective considerations; reflection for critical consciousness; and safe spaces and resistance.https://digitalcommons.fairfield.edu/education-books/1065/thumbnail.jp
Collaboration as a driver of EDI: How Collaborative Activities Drive the Development and Implementation of Employee-Driven Innovation Initiatives
No full textA growing perspective on innovation suggests that significant innovation can stem from employees' daily activities. Traditional innovation practices often delegate decision-making to a select group, typically R&D departments or specialized units. However, this approach overlooks the innovation potential distributed across all employees in an organization. Recent understanding challenges this traditional view, emphasizing that all employees possess the potential for innovation. Recognizing and harnessing this potential can lead to more distributed and effective innovation practices within organizations. This concept is referred to as Employee-Driven Innovation.In the context of Employee-Driven Innovation (EDI), collaboration is crucial for successful development and implementation. Effective collaboration, reliant on structures promoting knowledge exchange, skill development, and resource sharing, amplifies an organization's performance by capitalizing on individual strengths and expertise. However, the specific impact of collaboration on EDI practices is not well-understood, creating a gap in the literature and an opportunity to explore how collaboration influences EDI. Understanding these dynamics can inform and shape effective EDI practices. Therefore, it's essential to investigate the influence of collaborative activity on EDI, guiding the formation of effective strategies and driving successful EDI practices.This research narrows its focus to the development and implementation phase of Employee-Driven Innovation (EDI), as the literature suggests this phase is most influenced by collaborative activities and the organizational context allows deeper research into this specific phase. The central question being explored in this research is: how do collaborative activities drive the development and implementation of EDI initiatives?To address this, a case study is conducted within a single organization, Stedin, a grid operator in the Netherlands. The study encompasses several EDI initiatives and involves questioning both the initiators of the initiatives and collaborators during the development and implementation phase. A semi-structured interview format is used to gather insights.This research reveals key insights into the contrasting collaborative activities of the "fuzzy front end" and the "back end" of the development and implementation process of EDI initiatives. The fuzzy front end, characterized by exploration, thrives on dynamic, distant, and informal collaboration. These characteristics facilitate swift interactions, overcome organizational resistance, and prevent collective decision-making structures, thus promoting speed and flexibility.Conversely, the back end, typically more specialized and complex, benefits from stable, intimate, and homogeneous collaboration. This phase involves a time-consuming and complex role transfer, transitioning the EDI to an innovation that can be adopted organization-wide. Stable, homogeneous and intimate collaboration ensures effective implementation and a smooth transition of ownership...Management of Technology (MoT

Integrating RFID data with EDI business processes
No full textThesis (M. Eng. in Logistics)--Massachusetts Institute of Technology, Engineering Systems Division, 2005.Includes bibliographical references (leaves 42-46).Radio Frequency Identification (RFID) technology, an important component in the enterprise IT infrastructure, must be integrated into the legacy IT system. This thesis studies how RFID technology can be integrated into the existing Electronic Data Interchange (EDI) infrastructure, particularly how RFID can be used in the current EDI exchange process to accelerate the receiving process. After detailed review of current receiving process and relevant data specification, the author finds it possible to replace the current manual receiving process by RFID enabled automatic receiving and reconciliation process. A middleware is proposed to implement this approach.by Yan Chen.M.Eng.in Logistic
