tf-siammask 1.0.4

SiamMask implementation by Tensorflow 2

tf-siammask

SiamMask implementation with Tensorflow 2.

Install

pip install tf-siammask

Example

import numpy as np
import PIL.Image
import siammask

sm = siammask.SiamMask()

# Weight files are automatically retrieved from GitHub Releases
sm.load_weights()

# Adjust this parameter for the better mask prediction
sm.box_offset_ratio = 1.5

img_prev = np.array(PIL.Image.open('data/cat1.jpg'))[..., ::-1]
box_prev = np.array([[227, 184], [381, 274]])
img_next = np.array(PIL.Image.open('data/cat2.jpg'))[..., ::-1]

# Predicted box and mask images is created if `debug=True`
box, mask = sm.predict(img_prev, box_prev, img_next, debug=True)

Test data

	Previous frame	Next frame
File name	./data/cat1_with_box.jpg	./data/cat2.jpg
Image

Predicted mask for ./data/cat2.jpg
