Hue Range Dominance Index (HRDI) algorithm
Project description
huedominance
Provides Hue Range Dominance Index (HRDI) algorithm — a new vegetation index proposed for PhenoCam plant phenology image analysis.
For comparison with Green Chromatic Coordinate (GCC), a gcc
function is available, too.
To install:
pip3 install huedominance
To use from command line (example):
python3 -m huedominance 100 170 green_leaves.jpg
To use in your Python code:
from huedominance.hrdi import hrdi
from huedominance.gcc import gcc
from PIL import Image
image = Image.open('/path/to/your/image')
green_leaves_hrdi, hrdi_image = hrdi(image, 100, 170, makeIllustration = True)
green_leaves_gcc, gcc_image = gcc(image, makeIllustration = True)
hrdi_image.save('/path/to/hrdi/illustrative/signal/image', 'JPEG')
gcc_image.save('/path/to/gcc/illustrative/signal/image', 'JPEG')
red_leaves_hrdi, _ = hrdi(image, -30, 10)
Please refer to Python help on function hrdi
for details about the algorithm.
