It provides algorithms for reading/writing images, filtering (noise reduction, edge detection), geometric transforms, segmentation (thresholding, watershed, active contours), object measurement (area, intensity, shape descriptors), and feature detection. Images are represented as NumPy arrays, enabling seamless integration with NumPy, SciPy, matplotlib, and pandas. Widely used for fluorescence microscopy, histology, and general bioimage analysis.\n\n## When to Use\n\n- Preprocessing fluorescence microscopy images: background subtraction, denoising, illumination correction\n- Segmenting cells, nuclei, or organelles using thresholding or watershed\n- Measuring object properties: area, perimeter, intensity statistics, shape descriptors\n- Applying morphological operations: erosion, dilation, opening, closing, fill holes\n- Detecting keypoints or local features in biological images\n- Converting between image formats and color spaces\n- Use `OpenCV` instead for real-time video processing or GPU-accelerated operations\n- For deep-learning cell segmentation, use `CellPose` instead (better accuracy for touching cells)\n- Use `napari` instead for interactive multi-dimensional image visualization and annotation\n- For whole-slide image tiling, use `PathML` or `histolab` instead\n\n## Prerequisites\n\n- **Python packages**: `scikit-image`, `numpy`, `scipy`, `matplotlib`\n- **Input requirements**: Images as files (TIFF, PNG, JPEG) or NumPy arrays; fluorescence images as 2D/3D grayscale arrays\n- **Environment**: Python 3.9+\n\n```bash\npip install scikit-image numpy scipy matplotlib\n\n# For reading proprietary microscopy formats\npip install tifffile aicsimageio\n\n# Verify\npython -c \"import skimage; print(skimage.__version__)\"\n```\n\n## Quick Start\n\n```python\nfrom skimage import io, filters, measure\nimport numpy as np\n\n# Load → denoise → threshold → measure\nimg = io.imread(\"cells.tif\")\nimg_smooth = filters.gaussian(img, sigma=1.5)\nthreshold = filters.threshold_otsu(img_smooth)\nbinary = img_smooth > threshold\n\nregions = measure.regionprops(measure.label(binary))\nprint(f\"Found {len(regions)} objects\")\nprint(f\"Mean area: {np.mean([r.area for r in regions]):.1f} px²\")\n```\n\n## Core API\n\n### Module 1: Image I/O and Data Types\n\n```python\nfrom skimage import io, img_as_float, img_as_uint\nimport numpy as np\n\n# Read single image\nimg = io.imread(\"nuclei.tif\")\nprint(f\"Shape: {img.shape}, dtype: {img.dtype}\")  # (512, 512), uint16\n\n# Read image collection from directory\nfrom skimage import io as ski_io\nimages = ski_io.ImageCollection(\"data/*.tif\")\nprint(f\"Loaded {len(images)} images\")\n\n# Type conversions (critical for correct arithmetic)\nimg_f = img_as_float(img)      # uint16 → float64, range [0, 1]\nimg_u8 = (img_f * 255).astype(np.uint8)  # → 8-bit\n\n# Save image\nio.imsave(\"output.tif\", img_u8)\n```\n\n```python\n# Multi-channel fluorescence (TIFF with CZYX or ZCYX dims)\nimport tifffile\n\nstack = tifffile.imread(\"multichannel.tif\")  # shape: (C, Z, Y, X)\ndapi = stack[0]   # DAPI channel\ngfp = stack[1]    # GFP channel\nprint(f\"DAPI: {dapi.shape}, GFP: {gfp.shape}\")\n\n# Maximum intensity projection along Z\nmip = dapi.max(axis=0)\nio.imsave(\"dapi_mip.tif\", mip)\n```\n\n### Module 2: Filters and Preprocessing\n\n```python\nfrom skimage import filters, restoration\nimport numpy as np\n\n# Gaussian blur (denoising, smoothing)\nfrom skimage.filters import gaussian\nsmoothed = gaussian(img, sigma=2.0)\n\n# Median filter (salt-and-pepper noise removal)\nfrom skimage.filters import median\nfrom skimage.morphology import disk\ndenoised = median(img, footprint=disk(3))\n\n# Top-hat transform (background subtraction for uneven illumination)\nfrom skimage.morphology import white_tophat, disk\nbackground_removed = white_tophat(img, footprint=disk(50))\nprint(f\"Background removed: range [{background_removed.min()}, {background_removed.max()}]\")\n```\n\n```python\n# Edge detection\nfrom skimage.filters import sobel, laplace, prewitt\n\nedges_sobel = sobel(img_as_float(img))\nedges_laplace = laplace(img_as_float(img))\n\n# Difference of Gaussians (blob-like structure detection)\nfrom skimage.filters import difference_of_gaussians\nblob_enhanced = difference_of_gaussians(img_as_float(img), low_sigma=1, high_sigma=3)\n\n# Contrast enhancement (CLAHE: local histogram equalization)\nfrom skimage.exposure import equalize_adapthist\nenhanced = equalize_adapthist(img_as_float(img), clip_limit=0.03)\n```\n\n### Module 3: Thresholding and Segmentation\n\n```python\nfrom skimage import filters, morphology, segmentation\nfrom skimage.color import label2rgb\nimport numpy as np\n\n# Automatic thresholding methods\nfrom skimage.filters import (threshold_otsu, threshold_li,\n                              threshold_triangle, threshold_yen)\n\nimg_f = img_as_float(img)\nprint(f\"Otsu: {threshold_otsu(img_f):.3f}\")\nprint(f\"Li: {threshold_li(img_f):.3f}\")\n\n# Apply threshold and clean binary mask\nbinary = img_f > threshold_otsu(img_f)\nbinary_clean = morphology.remove_small_objects(binary, min_size=50)\nbinary_filled = morphology.remove_small_holes(binary_clean, area_threshold=100)\n```\n\n```python\n# Watershed segmentation (separate touching objects)\nfrom skimage.segmentation import watershed\nfrom skimage.feature import peak_local_max\nfrom scipy import ndimage as ndi\n\n# Distance transform → local maxima → watershed\ndistance = ndi.distance_transform_edt(binary_filled)\ncoords = peak_local_max(distance, min_distance=20, labels=binary_filled)\nmask = np.zeros(distance.shape, dtype=bool)\nmask[tuple(coords.T)] = True\nmarkers = ndi.label(mask)[0]\nlabels = watershed(-distance, markers, mask=binary_filled)\n\nprint(f\"Segmented objects: {labels.max()}\")\noverlay = label2rgb(labels, image=img_f, bg_label=0)\n```\n\n### Module 4: Morphological Operations\n\n```python\nfrom skimage.morphology import (erosion, dilation, opening, closing,\n                                 disk, ball, binary_erosion, binary_dilation)\n\n# Erosion and dilation\neroded = erosion(binary, footprint=disk(3))\ndilated = dilation(binary, footprint=disk(5))\n\n# Opening: erosion then dilation (removes small objects, smooths edges)\nopened = opening(binary, footprint=disk(3))\n\n# Closing: dilation then erosion (fills small holes)\nclosed = closing(binary, footprint=disk(5))\n\n# Skeletonization\nfrom skimage.morphology import skeletonize\nskeleton = skeletonize(binary)\nprint(f\"Skeleton pixels: {skeleton.sum()}\")\n```\n\n### Module 5: Measurement and Region Properties\n\n```python\nfrom skimage import measure\nimport pandas as pd\n\n# Label connected components\nlabeled = measure.label(binary_filled)\n\n# Extract region properties\nprops = measure.regionprops(labeled, intensity_image=img_as_float(img))\n\n# Convert to DataFrame\ndata = []\nfor r in props:\n    data.append({\n        \"label\": r.label,\n        \"area\": r.area,\n        \"perimeter\": r.perimeter,\n        \"eccentricity\": r.eccentricity,\n        \"mean_intensity\": r.mean_intensity,\n        \"max_intensity\": r.max_intensity,\n        \"centroid_y\": r.centroid[0],\n        \"centroid_x\": r.centroid[1],\n        \"bbox\": r.bbox,\n    })\n\ndf = pd.DataFrame(data)\nprint(f\"Objects: {len(df)}\")\nprint(df[[\"area\", \"mean_intensity\", \"eccentricity\"]].describe().round(2))\n```\n\n```python\n# Filter by property thresholds\ncells = df[(df[\"area\"] > 100) & (df[\"area\"] < 5000) & (df[\"eccentricity\"] < 0.9)]\nprint(f\"Valid cells: {len(cells)}\")\n\n# Measure co-localization: fraction of channel-1 signal in channel-2 positive mask\nfrom skimage.measure import regionprops_table\nimport numpy as np\n\n# For multi-channel images\ntable = regionprops_table(\n    labeled, intensity_image=np.stack([dapi, gfp], axis=-1),\n    properties=[\"label\", \"area\", \"mean_intensity\"]\n)\n```\n\n### Module 6: Feature Detection and Transforms\n\n```python\nfrom skimage.feature import blob_log, blob_dog, corner_harris, corner_peaks\nfrom skimage import transform\n\n# Laplacian of Gaussian blob detection (nuclei, puncta)\nblobs = blob_log(img_as_float(img), min_sigma=5, max_sigma=20,\n                  num_sigma=5, threshold=0.05)\nprint(f\"Blobs detected: {len(blobs)}\")\n# blobs columns: [y, x, sigma] where radius = sqrt(2) * sigma\n\n# Difference of Gaussians (faster alternative)\nblobs_dog = blob_dog(img_as_float(img), min_sigma=5, max_sigma=20, threshold=0.02)\n```\n\n```python\n# Geometric transforms\nfrom skimage import transform\n\n# Rescale\nimg_small = transform.rescale(img_as_float(img), 0.5)\n\n# Rotate\nimg_rotated = transform.rotate(img_as_float(img), angle=15, resize=True)\n\n# Affine registration (align two images)\nfrom skimage.registration import phase_cross_correlation\nshift, error, _ = phase_cross_correlation(ref_img, moving_img)\nprint(f\"Alignment shift: {shift} px, error: {error:.4f}\")\n```\n\n## Key Concepts\n\n### Image Arrays and Conventions\n\nscikit-image represents images as NumPy arrays. Shape conventions:\n\n| Image Type | Shape | dtype |\n|-----------|-------|-------|\n| Grayscale 2D | `(H, W)` | uint8, uint16, float64 |\n| RGB color | `(H, W, 3)` | uint8 |\n| Multichannel | `(H, W, C)` | any |\n| Z-stack | `(Z, H, W)` | any |\n\n**dtype matters**: Most algorithms expect `float64` in [0, 1]. Use `img_as_float(img)` before processing; convert back with `img_as_uint(img)` for saving.\n\n## Common Workflows\n\n### Workflow 1: Fluorescence Cell Segmentation and Measurement\n\n**Goal**: Segment DAPI-stained nuclei and measure GFP fluorescence per nucleus.\n\n```python\nfrom skimage import io, filters, morphology, measure, img_as_float\nfrom skimage.segmentation import watershed\nfrom skimage.feature import peak_local_max\nfrom scipy import ndimage as ndi\nimport pandas as pd\nimport numpy as np\nimport tifffile\n\n# Load 2-channel image (DAPI=ch0, GFP=ch1)\nimg = tifffile.imread(\"cells.tif\")\ndapi = img_as_float(img[0])\ngfp = img_as_float(img[1])\n\n# Segment nuclei from DAPI channel\ndapi_smooth = filters.gaussian(dapi, sigma=2)\nthreshold = filters.threshold_otsu(dapi_smooth)\nbinary = dapi_smooth > threshold\nbinary = morphology.remove_small_objects(binary, min_size=200)\nbinary = morphology.remove_small_holes(binary, area_threshold=500)\n\n# Watershed to separate touching nuclei\ndistance = ndi.distance_transform_edt(binary)\ncoords = peak_local_max(distance, min_distance=30, labels=binary)\nmask = np.zeros_like(distance, dtype=bool)\nmask[tuple(coords.T)] = True\nmarkers = ndi.label(mask)[0]\nlabels = watershed(-distance, markers, mask=binary)\n\n# Measure GFP per nucleus\nprops = measure.regionprops(labels, intensity_image=gfp)\ndf = pd.DataFrame([{\n    \"nucleus_id\": p.label,\n    \"area_px2\": p.area,\n    \"gfp_mean\": p.mean_intensity,\n    \"gfp_max\": p.max_intensity,\n} for p in props])\n\ndf.to_csv(\"nucleus_measurements.csv\", index=False)\nprint(f\"Nuclei: {len(df)}, mean GFP: {df['gfp_mean'].mean():.3f}\")\n```\n\n### Workflow 2: Batch Image Processing\n\n**Goal**: Apply the same preprocessing and measurement pipeline to a folder of images.\n\n```python\nfrom pathlib import Path\nfrom skimage import io, filters, measure, img_as_float, morphology\nimport pandas as pd\n\nresults = []\nfor img_path in sorted(Path(\"data/\").glob(\"*.tif\")):\n    img = img_as_float(io.imread(img_path))\n    if img.ndim == 3:\n        img = img.mean(axis=-1)  # convert RGB to grayscale\n\n    # Preprocess\n    smooth = filters.gaussian(img, sigma=1.5)\n    thresh = filters.threshold_otsu(smooth)\n    binary = morphology.remove_small_objects(smooth > thresh, min_size=50)\n\n    # Measure\n    labeled = measure.label(binary)\n    props = measure.regionprops(labeled, intensity_image=img)\n    for p in props:\n        results.append({\n            \"image\": img_path.stem,\n            \"object_id\": ","tagline":"Python image processing for microscopy and bioimage analysis.
