A Quick Fix for Incorrect Argument Name

[donglihe-hub]

Summary

This PR fixes a mismatch in argument naming that causes voxel-based feature extraction to fail when using a progressReporter.

Currently, running voxel-based extraction raises the following error:

TypeError: _DummyProgressReporter.init() got an unexpected keyword argument 'total'

This happens because _getProgressReporter() passes a "total" argument, while the _DummyProgressReporter class expects "_total" instead.

Fix

Rename "_total" to "total" in _DummyProgressReporter.init().

Minimal Reproduction

import numpy as np
import SimpleITK as sitk
from radiomics import featureextractor

np.random.seed(0)
img_np = np.random.rand(32, 32, 32).astype(np.float32)
mask_np = np.ones_like(img_np, dtype=np.uint8)

img_sitk = sitk.GetImageFromArray(img_np)
mask_sitk = sitk.GetImageFromArray(mask_np)
img_sitk.SetSpacing((1.0, 1.0, 1.0))
mask_sitk.CopyInformation(img_sitk)

extractor = featureextractor.RadiomicsFeatureExtractor(voxelBased=True)
extractor.disableAllFeatures()
extractor.enableFeatureClassByName("firstorder")

result = extractor.execute(img_sitk, mask_sitk)
print("Returned keys:", list(result.keys())[:10])
