Technical discussion about Matlab and issues related to Digital Signal Processing.
Hi ! I am doing my final project about event detection in indoor video surveillance, I am using Axis 207w network camera, I did the implementation to read the video and analysize the images to classify the events in the scene. I want to modify the system by using the audio also to robust the system. the axis207w has already built in microphone, but I have problem to record avi movies (containing audio and video) in the PC. with only video I don't have problem. and also in delay, when I play liveshow in the PC, I can easy notice the big delay between images and video (more than 3 seconds), so please if someone has ideas to solve the problems,1) record avi movies including audio from axis207w network camera. 2) how to analysis audio in matlab to be synchronized with the images. I already wrote the function to read avi with audio, but I don't know how to connect the information from audio signal to each frame, (considering the delay). thank you a lot Saleh
