streamer_analysis

Utility for comparing observed solar streamer latitude against models

Compilation

Make sure that the following libraries and packages are installed on your machine:

boost '>=1.64'
opencv '>=3.0'
cmake '>=3.8'

Compile as you would with any other CMake project:

# navigate to the project folder first
$ mkdir build
$ cd build
$ cmake ..
$ make

Running

The program requires a directory containing image files as its first argument, and an output file path as its second argument:

$ ./streamer_analysis
USAGE: stereo-reader data_dir csv_output_file

The program will provide an interface to click streamers, thereby tracing a line from the center to their tip, and then record these angles in the output file. The controls are as follows:

• Click to record a streamer angle (this will turn the line from blue to rosa)
• Rosa lines will be recorded in the output file
• Hit spacebar at any time to continue to the next image
• The program will automatically terminate when the last image is reached
