Packages used by file-metadata
[edit]| Name | PyPI | Conda | Ubuntu | 2.6 | 2.7 | 3.3 | 3.4 | 3.5 | CI | Comments |
|---|---|---|---|---|---|---|---|---|---|---|
| exiftool | - | yes | - | - | - | - | - | CPAN | We are downloading the perl script and running it with perl. | |
| ffmpeg or libav | - | yes | yes | - | - | - | - | - | ffmpeg was removed since Ubuntu trusty. libav is available in all versions. We are using the linux static builds if file-metadata is running on linux, else finding the executable in the PATH, else throw an error. | |
| ZXing | - | no | no | - | - | - | - | - | Travis | We download the jar files and run them with java. |
| numpy | yes | yes | yes | not supp-orted | yes | not supp-orted | yes | yes | Travis | Installed from pypi |
| magic | yes | yes | yes | yes | yes | yes | yes | yes | Travis | Note that the python-magic in pypi and Ubuntu are different packages, but we support both. |
| cv2 | no | yes | yes | yes | yes | v3.x only | v3.x only | v3.x only | buildbot | TODO Probably need this for haarcascade human detection |
| scikit-image | yes | yes | yes | not supp-orted | yes | not supp-orted | yes | yes | Travis | This is a replacement for OpenCV, more pythonic, easy to install with pip. Only con is it does not have haarcascades. |
| pycolorname | yes | no | no | no | yes | yes | yes | yes | CircleCI | Installed from pypi |
| dlib | yes | yes | no | no | yes | Installed from pypi. But needs boost-python | ||||
| cyvlfeat | yes | yes | no | no | yes | not supp-orted | yes | yes | Travis | TODO This is the most probably alternative to SLIC/JSEG ? |
| OpenCV (own) | TODO Do we still need this ? | |||||||||
| pywt | yes | yes, but not supp-orted | yes | Travis | TODO ? | |||||
| Wand | yes | yes | yes | yes | yes | yes | yes | yes | Travis | Installed from PyPI. Prompts to install the apt-get dependency. |

Packages used by catimages (and not by file-metadata)
[edit]| Name | Comments |
|---|---|
| scipy | Was only being used to find FFT Peaks in Edge detection ... A huge dependency for something like that. Would rather implement it myself / find alternative. |
| cv | Deprecated in favor of cv2 |
| pyexiv2 | exiftool provides more data and is more stable |
| gtk | Only used to find intersection of rectangles. We can make our own function for this. |
| music21 | The info provided by music21 can be got using exiftool+libav. Hence, it's redundant. Both libav and exiftool are stable and accurate. |
| pydmtx | Not maintained since 2011. Use zxing instead as it provides DataMatrix, QR and 1D barcodes. |
| zbar | Not updated since 2009. Use zxing instead as it provides DataMatrix, QR and 1D Barcodes. |
| bob + bob.flandmark | Use dlib instead. As dlib is easier to install. |
| yaafe | The data got from this is not being used for any analysis right now. Also, probably use librosa instead if needed. |
| jseg | ZIP File - Need better alternative |
| slic | ZIP File - Need better alternative |
| GI+rsvg+Cairo | Using Imagemagick's wand instead, as it also has support for XCF (Gimp) files. ImageMagick internally uses rsvg if it's available, or has it's own implementation if it isn't available. |
| py_w3c | Was used to check SVG's xml. Using python's XML tree parser instead. |
