Kmeans algorithm for Yolo anchor boxes.
Just import this python file and use it.
Run the following code:
import numpy as np
from numpy.random import rand
import matplotlib.pyplot as plt
from kmeans import kmeans, iou_dist
n_data = 100
data_boxes = rand(n_data*2).reshape((n_data, 2))
center = kmeans(data_boxes,
n_cluster=3,
dist_func=iou_dist,
stop_dist=0.01)
plt.scatter(data_boxes[..., 0], data_boxes[..., 1])
plt.scatter(center[..., 0],
center[..., 1])
plt.title("Use random data as an example")
plt.legend(["data", "center"])
plt.show()
or type python kmeans.py in your terminal.
You will get something like this:
