### How to use |
|
|
|
Here is how to use this model: |
|
|
|
```python |
|
from transformers import cellseg_sribd |
|
from skimage import io, segmentation, morphology, measure, exposure |
|
import numpy as np |
|
import tifffile as tif |
|
import requests |
|
|
|
img_name = 'cell_00010.png' |
|
def normalize_channel(img, lower=1, upper=99): |
|
non_zero_vals = img[np.nonzero(img)] |
|
percentiles = np.percentile(non_zero_vals, [lower, upper]) |
|
if percentiles[1] - percentiles[0] > 0.001: |
|
img_norm = exposure.rescale_intensity(img, in_range=(percentiles[0], percentiles[1]), out_range='uint8') |
|
else: |
|
img_norm = img |
|
return img_norm.astype(np.uint8) |
|
if img_name.endswith('.tif') or img_name.endswith('.tiff'): |
|
img_data = tif.imread(img_name) |
|
else: |
|
img_data = io.imread(img_name) |
|
# normalize image data |
|
if len(img_data.shape) == 2: |
|
img_data = np.repeat(np.expand_dims(img_data, axis=-1), 3, axis=-1) |
|
elif len(img_data.shape) == 3 and img_data.shape[-1] > 3: |
|
img_data = img_data[:,:, :3] |
|
else: |
|
pass |
|
pre_img_data = np.zeros(img_data.shape, dtype=np.uint8) |
|
for i in range(3): |
|
img_channel_i = img_data[:,:,i] |
|
if len(img_channel_i[np.nonzero(img_channel_i)])>0: |
|
pre_img_data[:,:,i] = normalize_channel(img_channel_i, lower=1, upper=99) |
|
|
|
|
|
|
|
model = cellseg_sribd.from_pretrained("Lewislou/cellseg_sribd") |
|
with torch.no_grad(): |
|
output = model(pre_img_data) |
|
|
|
``` |
