Thresholding

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

Synopsis

threshold

The program expects to find an image in the JPEG format in the current directory named input.jpg, and produces two images in JPEG format in the current directory in return, named out-threshold-binary.jpg and out-threshold-binary-inv.jpg, where a thresholding and an inverse thresholding, respectively, has been applied.

The program doesn't take any command line arguments.

Specific requirements

Build requirements

A C++ compiler compliant with C++11 or above
The JPEG library installed and configured.

Execution requirements

threshold expects to find an image in the JPEG format in the current directory.
