Adaptive Thresholding

Adaptive Thresholding capabilities in GIL are demonstrated by the program adaptive_threshold, compiled from the sources example/adaptive_threshold.cpp.

Synopsis

adaptive_threshold

The program doesn't take any argument on the command line.

adaptive_threshold expects to find an image called test_adaptive.png in the current directory, and produces one image for each thresholding method:

• out-threshold-adaptive-mean.png
• out-threshold-adaptive-mean-inv.png
• out-threshold-adaptive-gaussian.png
• out-threshold-adaptive-gaussian-inv.png.

Specific requirements

Build requirements

• A C++ compiler compliant with C++14 or above
• The PNG library installed and configured.

Execution requirements
