Emgu CV is a cross-platform .NET wrapper to the OpenCV image processing library
OpenCV (Open Source Computer Vision) is a library for real time computer vision: * Human-Computer Interaction; Object Identification, * Face and Gesture Recognition; * Segmentation and Recognition; Motion Tracking, Motion Understanding; * Stereo and Multi-Camera Calibration and Depth Computation; Mobile Robotics.
"The results end up very close but the emgucv image comes out a little bit blurrier than the opencv image"
from question "Why might EmguCV Gaussian blur not return identical results as OpenCV Gaussian blur?"
"Unless you re doing very heavy processing working with a single frame is probably faster than transferring it to the server as far as i know emgucv in c# isn t considerably slower than opencv in c c++"
from question "Sending bitmaps over ethernet and then back again (c# and c)"
