Segmentatie

Supervised
Unsupervised

Ongesuperviseerde segmentatie

Simple Linear Iterative Clustering (SLIC)

Ongesuperviseerde segmentatie (SLIC)

# Import the modules
from skimage.segmentation import slic
from skimage.color import label2rgb


# Obtain the segments
segments = slic(image)


# Put segments on top of original image to compare
segmented_image = label2rgb(segments, image, kind='avg')


show_image(image)
show_image(segmented_image, "Segmented image")

Ongesuperviseerde segmentatie (SLIC)

Meer segmenten

# Import the modules
from skimage.segmentation import slic
from skimage.color import label2rgb


# Obtain the segmentation with 300 regions
segments = slic(image, n_segments= 300)

# Put segments on top of original image to compare
segmented_image = label2rgb(segments, image, kind='avg')


show_image(segmented_image)

Meer segmenten
