Eos Webcam Utility Beta 0.9.0 For Windows Download

Until last week Microsoft Teams worked in combination with the EOS webcam utility and my Canon EOS camera.Since today, every meeting I start with my camera on results in a crash of Microsoft Teams with the following error message:
1: This camera is not officially supported by the EOS webcam utility, but it has been working flawlessly until now. Also, the fact that other software (e.g. the browser) still can use this camera as a webcam signals to me that this is not the issue.
A real-time system for noncontact measurement the EEG spectral index was developed with the IR web-cam (Figure 9). This system comprised an IR webcam, a near-IR illuminator (IR lamp), and a personal computer for analysis. The IR web-cam was developed by reconfiguring a high-definition web-cam (HD-5000, Microsoft Inc., USA) by replacing the IR filter with an IR pass filter (Kodac Inc., USA) inside the webcam. A real-time system can be non-contact measure the relative power for low beta in FP1, mid beta in FP1 region, SMR in FP1, beta in F3, high beta in F8, gamma in P4, and mu in C4 using the IR web-cam. This system was developed using Visual C++ 2010 and OpenCV 2.4.3, and the signal processing used LabVIEW 2010 (National Instruments Inc., Austin, TX, USA).
In this study brain activity was measured using a low-cost IR webcam. Pupillary rhythms with harmonic frequency (1/100 f) revealed a high correlation in our protocol with seven parameters (relative powers) of the EEG spectral index [i.e., low beta (FP1), mid beta (FP1), SMR (FP1), beta (F3), high beta (F8), gamma (P4), and mu (C4)] during the changes of the physiological states (arousal, relaxation, positive, negative, and neutral states). However, in order for the proposed method to be applied in various fields, the method needs to be investigated under different conditions (rapid illumination changes, other physiologic conditions, or other stimuli for causing physiological state) that were not included in the current protocol. To overcome the above limitations in further studies, the proposed method may measure and evaluate brain activity in various application fields using a simple, low-cost, non-contact system. Because measurement of brain activity using sensors has traditionally required complex and expensive equipment, and involved the inconveniences and burden of sensor attachment.
