Detect blobs

[lbdc]

Just wondering if there is a way for DVR-Scan to detect "blobs of pixel" or "continuous areas" to prevent false detection due to rain, snow and noise.

If not could this be implemented as enhancement?

It's definitely technically possible, one could supply an image as a mask (e.g. a transparent .png). Not sure when I'll be able to get to this, but I'm more than open to implementing it for sure, great idea. Or were you thinking of something more automated, like blurring the image and using a morphological filter on the more stable areas of the image?

In the meantime, note that if you get the latest source code, you can supply a rectangular ROI (see this comment for details).

Hopefully with adjusting kernel size and the new region editor, it should be easier to mask out certain areas and small blobs.
