Step-by-step guides
- Generating a histogram of pixel intensities from each channel.
Predefined tasks
Some tasks are included in the Anchor distribution, to be easily
run from the command-line with -t taskname.
To run a task, open a shell (e.g. Command Prompt or Powershell in Windows), change to a directory with images, and then:
Next, consider enabling additional outputs with the -o options or refining your
inputs with the -i options.
Tip: In Windows, hold the shift key when right-clicking on a folder in Windows Explorer to open a Command Prompt or Powershell in that folder.
Image processing
| Task Name | Input Type | Description |
|---|---|---|
| histogram | images | extracts histograms of the intensity values an image. |
| mean | images | creates a mean-intensity projection of all inputs. |
| meanResize | images | scales inputs to fixed dimensions, and then a mean-intensity projection. |
| resize | images | scales each image to fit inside fixed dimensions, preserving aspect ratio. Optionally accepts -pr. |
| stack/montage | images (3D) | produces a tiled montage of all z-slices of a 3D image |
Image segmentation
| Task Name | Input Type | Description |
|---|---|---|
| text | images | finds text-regions in images. |
Feature extraction
| Task Name | Input Type | Description |
|---|---|---|
| feature/hog | images | extracts a HOG feature descriptor for all images. |
| feature/metadata | images | extracts some basic metadata as features, including dimensions. |
File copying / conversion
| Task Name | Input Type | Description |
|---|---|---|
| anonymize | any files | copies files, randomizing order and hiding the original naming. |
| convert | images | converts the file format of input images. |
| copy | any files | copies files, preserving naming and subdirectory structure. |
Summarizing inputs
| Task Name | Input Type | Description |
|---|---|---|
| countFiles | any files | counts the number of input-files. |
| list | any files | shows a line inputName -> inputPath for each input. |
| listNames | any files | shows each input’s name on a separate line. |
| listPaths | any files | shows each input’s path on a separate line. |
| summarize | images | combines the summaries in summarizeImages and summarizePaths. |
| summarizeImages | images | summarizes image attributes (dimensions, bit depth etc.) |
| summarizePaths | any files | summarizes file attributes (size, patterns among the file-paths etc.) |
