BlobCounter - support for simpliest image mode: bit format #371

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I suppose in this case the routine will be easier to implement as the image 
will have only black or white pixels (as shown in Photoshop CS6 - first image 
mode from all available). It would be great to have it for compatibility 
purposes.

I intend to use this library in my work project so it would be nice to have 
such feature.

Do you mean to support 1 bpp images?

What is the aim? Are you doing some image processing or some computer vision in 
real time? Hardly see benefit of 1bpp images in computer vision.

I'm working on the task of visual tags identification inside documents 
represented as scanned image files. Tags are black squares. By default i 
receive documents in 1bpp format. Honestly i don't know yet is it possible to 
convert bitness on-the-fly but i suppose that this is preformance and memory 
costly and in my solution  performance matters much.

If you can suggest smth that can help i'll be glad.

I would just convert 1bpp image to 8bpp.
