working with compressed image topics

[mmp52]

Hello,

How can I make the algorithm subscribe to compressed image topic?
I am using usb_cam node of the ROS.
Also should using compressed images make the process faster or will I lose the same time to decompress the image?

Thank you
Metin

Hi,
I don't know if the code supports compressed images out-of-the-box, but as far as I know you can try to use a republisher node.
Hope this can help you.
