Image analyses using MATLAB in video conference system

In the thesis study, detailed information about video conferencing systems was obtained and video conferencing records were prepared within the scope of the implemented applications. Then, the video recordings were transferred to Matlab software and evaluated about the image quality of the cameras used in video conferencing applications by image analysis methods. In the study; the literature on video conferencing systems was reviewed. The research was conducted on the devices of video conferencing systems in the market. The "Logitech Group ConferenceCam" product, which provides group conference facilities, was reviewed and video conferencing applications were conducted using this product. For video conferencing, the "Logitech Group ConferenceCam" hardware, laptop computer and Skype interface software were used. "Icecream Screen Recorder" software was used to record video conferences. Matlab applications for three of recorded video conference calls were made. On the other hand, Iphone 5S was used for video recordings 1 and 2, and Iphone 7Plus was used for video recording 3, while the video conferencing included the "Logitech Group ConferenceCam" equipment connected to the Toshiba laptop computer. The aim of the study was to compare the Signal-to-noise ratio (SNR) values of images taken with different cameras. Evaluations were made on the camera qualities with the obtained values, but since the images were not obtained under the same ambient conditions, only the SNR values would be insufficient for direct connection of the camera image qualities.
