segmentation-mask-overlay 0.4.4

Plotting the segmentation masks has never been so exciting!

Segmentation mask overlay

If you ever wonder to overlay your segmentations onto a picture in the smoothiest way, you're in a right place.

Installation

pip install segmentation-mask-overlay

Description

Here you can take your segmentation map, put on an image individually or in a company. If you have a bunch of them, they will blend if touch each other.

You can even name them one by one, providing labels.

That's it! As simple as is. Now you are completely ready to laminate images with your segmentation.

How to use

import matplotlib.pyplot as plt
import numpy as np
from PIL import Image
from segmentation_mask_overlay import overlay_masks

# [Example] Load image
image = Image.open("cat.jpg").convert("L")
image = np.array(image)

# [Example] Mimic list of masks
masks = []
for i in np.linspace(0, image.shape[1], 10, dtype="int"):
    mask = np.zeros(image.shape, dtype="bool")
    mask[i : i + 100, i : i + 200] = 1
    masks.append(mask)

# [Optional] prepare labels
mask_labels = [f"Mask_{i}" for i in range(len(masks))]

# [Optional] prepare colors
cmap = plt.cm.tab20(np.arange(len(mask_labels)))[..., :-1]

# Laminate your image!
fig = array = overlay_masks(image, np.stack(masks, -1), mask_labels, return_type="mpl")

# Do with that image whatever you want to do.
fig.savefig("cat_masked.png", bbox_inches="tight", dpi=300)

CHANGELOG

• v0.4.4:
  • Dropped mandatory label arg in overlay_masks()
  • Added one-channel binary masks handling in overlay_masks()
