Index Filter and Sort
Filtering, sorting, and searching data in Encord Index is crucial for various reasons. It enables insights and actionable results on the following key aspects and more:
-
Identification of patterns, trends, or anomalies within a subset of the data.
-
Recognition of duplicates, outliers, and inconsistencies.
-
Removal of irrelevant, noisy, and erroneous data.
-
After filtering, sorting, and searching your data, use Collections with Annotate Projects to streamline your annotation process.
Encord Index provides the following methods:
-
Filter: Refine your searches using quality metrics, custom metadata, Collections, folder, data title, and data types.
-
Sort: Sort your data, in ascending or descending order, using quality metrics.
-
(Coming soon) Natural language search: Enter descriptive queries in everyday language to make it easier to find relevant images without the need for specific keywords or complex search parameters.
-
Embedding plot: A two-dimensional visualization technique used by Encord to represent high-dimensional data in a more interpretable form. Use the plot to select points within a specific rectangular area, thereby focusing on a particular subset of data points for in-depth analysis.
Filters
In the Index Explorer for a Project you can refine searches by data quality metrics, Collections, custom metadata, folders, data titles, and data types.
Tips
Filters provide the ability to include or exclude images based on your filtering criteria.
Data Quality Metrics
For more detailed information on Data Quality Metrics go here.
Title | Metric Type | Ontology Type |
---|---|---|
Area - Ranks images by their area (width/height). | image | |
Aspect Ratio- Ranks images by their aspect ratio (width/height). | image | |
Blue Value - Ranks images by how blue the average value of the image is. | image | |
Brightness - Ranks images by their brightness. | image | |
Contrast- Ranks images by their contrast. | image | |
Diversity - Forms clusters based on the ontology and ranks images from easy samples to annotate to hard samples to annotate. | image | |
Frame Number - Selects images based on a specified range. | image | |
Green Value- Ranks images by how green the average value of the image is. | image | |
Height - Ranks images by the height of the image. | image | |
Object Count - Counts number of objects in the image. | image | bounding box , checklist , point , polygon , polyline , radio , rotatable bounding box , skeleton , text |
Object Density - Computes the percentage of image area that is occupied by objects. | image | bounding box , polygon , rotatable bounding box |
Randomize Images - Assigns a random value between 0 and 1 to images. | image | |
Red Value - Ranks images by how red the average value of the image is. | image | |
Sharpness - Ranks images by their sharpness. | image | |
Uniqueness - Finds duplicate and near-duplicate images. | image | |
Width - Ranks images by the width of the image. | image |
Collections: Collections are a new way to save interesting groups of data units and labels, to support and guide your downstream workflow.
Custom Metadata: Custom metadata added to data units. The custom metadata added to data units in Folders persists to Annotate Projects and Active.
Tips
For information on importing custom metadata to an Annotate project, refer to Adding Metadata in the documentation.
Data Types: Data, labels, and Predictions can be filtered by: images, image sequences, image groups, and videos
To filter Index data:
-
Log in to the Encord platform.
The landing page for the Encord platform appears. -
Go to Index > Files.
The All folders page appears with a list of all folders in Encord.
- Click in to a folder.
The landing page for the folder appears and the View in Explorer button is enabled.
-
Click the View in Explorer button.
The Index Explorer page appears. -
Click Filters.
The Filters tab appears. -
Click Add Filter.
A menu appears. -
Add and configure the filters you need.
Images/video filter in the Explorer workspace.
Tips
Sort and use the natural language searches (natural language searches coming soon) to further help get the results you want.
After filtering, sorting, and searching, create an Index Collection.
Preset Filters
Preset filters provide a way to save your filtering criteria for use and reuse on other Folders. Preset filters are made up of global and local filter criteria.
Global filter criteria are filters, and their settings, that can apply to any Folder. For example, Data Quality Metrics like Area, Blue Value, and Sharpness.
Local filter criteria are filters that can only be applied to a specific Folder. For example, the following filters and their settings are likely only applicable to a specific Index Collection.
Create a Preset Filter
Create Presets (Preset Filters and their settings) from the Filter tab.
To create a Preset (Preset Filter and their settings):
-
Log in to the Encord platform.
The landing page for the Encord platform appears. -
Go to Index > Files.
The All folders page appears with a list of all folders in Encord.
- Click in to a folder.
The landing page for the folder appears and the View in Explorer button is enabled.
-
Click the View in Explorer button.
The Index Explorer page appears. -
Click Filters.
The Filters tab appears. -
Click Add Filter.
A menu appears. -
Add and configure the filters you need.
Images/video filter in the Explorer workspace. -
Click Presets > Create Presets once you have added all the filters you need and specified each filter's settings.
After creating the Preset you can use the Preset in this or any other Folder.
Use a Preset Filter in Index
Once you have created one or more Preset Filters, you can apply them to any of your Folders from the Filter tab.
Note
Global filters apply to any Folder, but Local filters only apply on the Folder where the Preset was created.
To create a Preset (Preset Filter and their settings):
-
