Thread Subject:
Capture multiple frames/images of a Moving Object

Subject: Capture multiple frames/images of a Moving Object

Message: 1 of 3

I am working on "Sing Language Translator" project. So far I have captured numbered signs from 0 to 10. Ran some operations like "Local Histogram" and "PCA". Then I trained matlab those signs using Probabilistic Neural Network (PNN). Now, I have saved those trained workspace and I can give input and match a single sign and get the matched result.
I give a single signed image as input now and use the previous trained and saved workspace to match and give me the result.

Now I want to make it more sequential or more automatic. I want to use a video camera or web camera. I'll move the hand and finger according to my signs. I'll not save the videos/images manually. Rather, when I will show a sign for a longer period of time, for example 4 or 5 second, matlab will capture an image or frame and process it and match it with the saved workspace and show me the result like I used to match a single image/sign before.

I'll show some signs one after another. But matlab will not capture any frame during the transection period. It will capture a frame only when the hand is showing a sign for a longer period of time for example 3 or 4 seconds.

Can anyone give me some ideas how I can do it..?

Dear Nehal!

I will try to help you if you can show me the code or part of the code for capturing.
