Improved Video Sub-Annotations

Attributes, Instance IDs,andText now exist independently of key frames in the video timeline, allowing you to more easily add them to the frames to which they apply. This prevents teams labelling video from having to manually add attributes to sequences that are interrupted by a key frame

Negative Filters

Quickly determine which files do not contain specific classes. Click on a filtered tag, class,annotator, item, or workflow stage twice to exclude it from your filters.

New APIs for Registering and Uploading External Files


Paired with brand new documentation, we've released a new upload API to simplify standard uploads, as well as uploads from external storage.

Text Sub-Annotations for Tags


Add an extra language layer to your tags. All tag classes now include the ability to include text as a subannotation.

Webhook Signatures & Documentation


All webhook payloads now include a V7 signature. We've also bolstered our documentation to help you easily set up webhooks in your datasets.

Tag During Upload


One of our most asked-for features is now possible via the new API - you can now tag and import files simultaneously.

 New Features  
🆕 CLI and REST API imports will be blocked when V7 detects that a filename already exists in the destination dataset and folder.  They will not be blocked if the file is being imported to a different folder. 


 Performance Improvements  
🚀 We've added caching to count-related endpoints to prevent high volumes of requests from impacting V7's performance. 

 Fixes  

🛠 Fixed an issue that prevented tags from being applied under certain filter parameters in the Data page.
🛠 Importing annotations to a dataset containing duplicate tags used to fail the upload - they are now overwritten with the imported tags
🛠 Fixed a rare issue that caused hand-drawn polygons to create small polygons outside of the polygon outline.
🛠 Resolved an issue that caused an error message when a team owner added their email address to the list of invited users when creating a V7 account.
🛠Fixed a display issue that caused annotations to jump around in the Annotations sidebar.
🛠 Polybool regions with less than 3 points which were created by an error when merging and subtracting are now filtered out at export.
🛠Fixed a slight regression that temporarily impacted import speed.
🛠 Fixed an issue that caused DICOM files with a capitalized extension (.DCM) to be handled differently than files with a .dcm extension.
🛠 Workforce managers were only able to assign files to other workers. They can now assign files to themselves.
🛠 Fixed an issue that caused the timer to run in inactive tabs if they were created but not opened immediately.
🛠 Fixed an issue that prevented files from being moved and assigned when using complex filter parameters.
🛠 Dataset thumbnails were greyed out when mixing external and locally-uploaded storage. They now display normally.
🛠 Fixed an issue that prevented large .svs file uploads from tiling and processing successfully.
🛠 Fixed an issue that caused storage limits to be counted incorrectly when tagging items in the New status.
🛠Fixed an issue that caused the arrows used to navigate between video frames and video files to be unresponsive.

Train & Run Models on Video, DICOM, and PDF files

Use your labelled video, DICOM, and PDF data to train a Neural Network,run it via the API, and use it to automatically label your data. All without ever leaving V7.

Stylus Support


For all those times you've ever wanted to label on your tablet - all annotation types now offer stylus support.

An improved timeline


Right click any label to add a key frame, change classes, or delete the annotation. Lengthening and shortening labels is also smoother than ever

Two Factor Authentication


All team members can now enable two factor authentication to help keep your data even more secure.

Frame-Specific Comments


Comments now appear on individual frames in the the video timeline to help you and your team share feedback on video and DICOM projects.

Freehand Polygons


Hold down the mouse when using the Polygon Tool to create smooth polygons with finer contours in a single click.

Scan Text Automatically 

Your team will never have to manually key in text again. Use the new Text Scanner model to detect and scan the text in any of your image datasets. 

A Better Brush Tool

Any polygon being adjusted with the Brush Tool now has a dashed appearance - Making it stand out on the canvas.
You can also enter the exact pixel size needed when adjusting the the Brush Tool's tip size.

A Richer Sidebar

Text, attributes, and other sub-annotations can be added directly from the sidebar.

New Filter: Comments


Quickly filter for all files that have received feedback from your team.

Drag to Rerun Auto-Annotate


Dragging the edges of the Auto-Annotate bounding box will now trigger the modelto rerun to track objects in video.

Reset Workflow in Bulk


Send files back to a New state to restart workflow without losing any of your annotations.

TIP Shift + Click  to add multiple options in your search query.

A New Report: File-Level Annotator Statistics


Download the Overview Report from the Dataset Overview page to see a breakdown of all of your images and videos, when were they added, when did labelling start, who worked on them, and for how long.

Train Neural Networks on Video Frames


You can now train models on videos whose frames are imported as individual images.

Everything is in Real-time

We want your data to feel alive. Statuses, assignments, quantities, datasets, now all update in real-time across your team.

This gives us the chance to bring even more collaborative features to V7, both for data scientists and annotators. Watch this space :)

15 times


That's how much faster annotations are now rendered on V7 compared to the sector leading web library.

500,000 points are tracked in this GIF without lag. And we wont' stop here!

No Loading


We're not just removing the need for refreshing - waiting is going as well. Load times are now instant on most file types. Over time, we'll reduce most load times to zero to offer the smoothest experience of any ML platform on the web.

DICOM is smart(er)


Just drop your DICOM studies, and V7 will re-order CT and MRI slices based on header values. Gone are the days of pre-processing your data.
Thanks to all our medical imaging users for the continuous tips and feedback!

Fun fact: That's our CEO's brain. Technically where V7 was born.

Video Annotation Track Size


A little window above video timelines allows you to define the default length of a new annotation. This should help reduce time spend lengthening and shortening their sizes.

TIP: You can turn any number of images into a sequence (which behaves like a video) by zipping it and renaming .zip to .mp4. Use this for multi-page PDFs, multi-camera setups, or to turn images back into a video.

Balance your classes


The dataset overview page got some new tools. Class balance histograms now show data by image and instances, and point out over/under representation of your classes. These are also isolated by annotation type.
