Re: [january-dev] January usage on Android?
Hope you are well Erwin.
We had a class in scisoft called "Downsample" which I didn't write but used to cut down images for different resolutions. I think it is already in another repo with a permissive license and could be moved to January...

Hi January team,

 

For an Android app we need to do some "simple" image processing to manipulate the camera video stream, which is really a sequence of RGBA frames.

It appears that the Android "virtual display ImageReader" offers the video stream as a bytebuffer on which a kind of "shape" can be defined in a similar way as January represents its DataSets if I remember correctly.

 

One particular case is where certain mobile devices appear to pass more "pixels" than the actual camera resolution.

I.e. they add a black area to the right in the camera image for some unimaginable reason, so we want to remove that.

 

I think we could use January slicing for that.


So the question is, would January Dataset construction (from a bytebuffer) and slicing be useable in an Android app?

 

thanks

erwin
