5.6.0
- 2022-08-05Events status added. Starting from this version, there is a new observable events$, where LIQA returns information about its status and errors.
LIQA informs about exact loading stages (allows to make progress bar)
LIQA informs about successful loading finish and successful camera start.
LIQA informs about issues like "camera access not granted" or general errors, that occurred during loading or execution.
See examples of events parsing here: Events parsing
Fixed
Several minor issues are fixed.
5.5.1 - 5.5.0

5.5.1 - 5.5.0
- 2022-06-15Fixed
We changed the way how LIQA treats provided canvas
for video / requested size of canvas
. previously, LIQA attempted to set up a videocapture from device camera to the desired canvas size. In case if device camera was not able to provide such resolution or the aspect ratio was incompatible with camera, the video either did not start (desktops, laptops) or started with very skewed face image (tablets, mostly Apple iPad).
New version fixes this: LIQA adjusts the requested canvas size to the available camera size and centers the canvas with video. This allows LIQA start correctly on nearly any device with somewhat like responsive UI.
5.4.0
- 2022-03-31
5.4.0
- 2022-03-31We added a new feature to check final image, captured by LIQA!
Previously, LIQA performed analysis of real time video frames, but after approving the "photo capturing" action, the final image was not processed. This caused the situation that some users took pictures of not propper quality and LIQA had not validated it.
Fixed
We improved protection of API methods from incorrect input type. Previously it could cause an issue with constant "
too close
" output inqualityStatus$.face_position
attribute.We updated internal dependencies on FaceDetection models. This allowed to reduce time for one frame processing in real time video. The improvement is mostly observed on some devices of 2018 production year.
iOS 15.3 has a vulnerability in Safary web browser. The issue prevents LIQA from correct behaviour. The issue result in case that calling
.play()
method of LIQA 2nd time result in failing video frames processing.

Fixed bugs with camera on iOS devices and distance levels
Added iOS 15.0 support

5.1.0
- 2021-09-17Fixed
Reworked head rotation estimation model. Improved head angles tracking on different distances from camera.
Reworked distance estimation model. Fixed issue with incorrect distance calculation for head rotated to the left / to the right.
Reworked camera user agents: now it is specific for Android and iOS and allows the correct aspect ratio settings for different devices.
Fixed behaviour for devices with multiple cameras available.
New
Modified settings for distance tracking, added new parameter in config. Added new output for
facePosition
observable output.
5.0.7 - 5.0.8

5.0.7 - 5.0.8

5.0.1, 5.0.2
- 2021-07-12
5.0.1, 5.0.2
- 2021-07-12Fixed
Selfie capture bug on some older iOS versions
config.imageFormat
is now stable
5.0.0

5.0.0
- 2021-06-26Fixed
Web-worker for math parallel calculation is now loaded with all the rest files and initiated from global space
Canvas and videotag initialization are now available as an option outside of LIQA. The initialized elements now can be passed as parameters in
liqa.init
call. The default behaviour is still an automatic initialization of canvas and videotag inside of LIQA.
New
New feature - Autocapturing
LIQA can now take photos automatically if the image quality is good for the following 3 seconds.
Activate this feature by setting a new parameter
autoSelfieCapture
inconfig.json
totrue
. LIQA will show a countdown overlay and perform selfie capturing by itself.
New feature - Landmarks (facial key points) prediction
LIQA can now return facial key points on a captured selfie image.
Activate this feature by setting a new parameter
predictLandmarks
inconfig.json
totrue
. LIQA will return a set of facial key points - landmarks (see Selfie capturing results parsing for more details). See the Observables: Data Collection for more details about a new RX-JS observable with landmarks output.
Changed
Changed behaviour of
captureSelfie
function: now LIQA will always automatically stop videostream after capturing the selfie. To restart it simply call theliqa.play
method.Now the resolution of the selfie image returned by LIQA is limited by 2000 x 2000 pixels. This size is optimal for uploading to the server and suitable for any AI analysis.
Reworked
qualityStatus
API: from now thefaceRotation
field of thequalityStatus$
Observable contains 7 values with clear problem descriptions with head rotation. Now the usage of this for visual feedback mapping became much easier. For more see here Observables: Data Collection
Documentation
We added new pages in our documentation:
If you are only thinking about trying LIQA, see here how to get it: Try LIQA: access request
If you are already developing your app with LIQA, see our updated Integration Guideline [JavaScript]
