pluginlib API to implement image processing features

[twdragon]

Should the node provide a pluginlib-based API and mechanism to perform frame-based postprocessing of the image before being published? Please share your opinions here!

@knorth55 @flynneva in the meantime, could you please share what you think about this?

@twdragon for me this sounds like scope creep and something that violates the single responsibility principle.

This packages purpose is purely meant to grab images from v4l devices and publish it to ROS, that's it.

[knorth55]

im not sure about your idea but is it like image_transport plugin?
if so, it is better to make another package with image_transport plugin

[twdragon]

@flynneva @knorth55 the idea is to provide lightweight API to make some basic processing, like flipping for example, avoiding republishing and using the image_proc package

[knorth55]

@twdragon i think it should be separate package. this package is just for grabbing image from usb device and publish.
if you want to do more postprocessing, you should make another node or nodelet in another package.

OK, here we should keep the singular responsibility, so I close this discussion
