ImageDataCSV

ImageDataProcessor Objects​

class ImageDataProcessor()

Processing for Image data, used when loading images

ImageDataCSV Objects​

class ImageDataCSV(CSVParser.CSVParser, ImageDataProcessor)

ApertureDB Image Data.

This class loads the Image Data which is present in a CSV file, and converts it into a series of ApertureDB queries.

Is backed by a CSV file with the following columns:

filename, PROP_NAME_1, ... PROP_NAME_N, constraint_PROP1, format

OR

url, PROP_NAME_1, ... PROP_NAME_N, constraint_PROP1, format

OR

s3_url, PROP_NAME_1, ... PROP_NAME_N, constraint_PROP1, format

OR

gs_url, PROP_NAME_1, ... PROP_NAME_N, constraint_PROP1, format

Example CSV file::

filename,id,label,constraint_id,format
/home/user/file1.jpg,321423532,dog,321423532,jpg
/home/user/file2.jpg,42342522,cat,42342522,png
...

Example usage:


    data = ImageDataCSV("/path/to/ImageData.csv")
    loader = ParallelLoader(db)
    loader.ingest(data)

or


    adb ingest from-csv /path/to/ImageData.csv --ingest-type IMAGE
info

In the above example, the constraint_id ensures that an Image with the specified id would be only inserted if it does not already exist in the database.

ImageUpdateDataCSV Objects​

class ImageUpdateDataCSV(SingleEntityUpdateDataCSV, ImageDataProcessor)

ApertureDB Image CSV Parser for Adding an Image and updating the properties on the image. Usage is in EntityUpdateDataCSV.

Note that this class will not change a blob in an existing entity. If looking to change a blob in an existing entity, look at ImageForceNewestDataCSV, but be careful of all caveats.

ImageForceNewestDataCSV Objects​

class ImageForceNewestDataCSV(BlobNewestDataCSV, ImageDataProcessor)

ApertureDB Image CSV Parser for Maintaining a Blob set with changing blob data. See BlobNewestDataCSV for usage.

ImageSparseAddDataCSV Objects​

class ImageSparseAddDataCSV(SparseAddingDataCSV, ImageDataProcessor)

ApertureDB Spare Loading Image Data.

ImageSparseAddDataCSV should be used the same as ImageDataCSV.

See SparseAddingDataCSV for description of when to use this versus ImageDataCSV.

Example CSV file::

filename,id,label,constraint_id,format
/home/user/file1.jpg,321423532,dog,321423532,jpg
/home/user/file2.jpg,42342522,cat,42342522,png
...

Example usage:


    data = ImageSparseAddDataCSV("/path/to/ImageData.csv")
    loader = ParallelLoader(db)
    loader.ingest(data)
