Observables: Data Collection
This page describes RxJS observables for collecting quality analysis results, final selfie images and technical information about LIQA status.
qualityStatus$: Observable<StatusData>
The qualityStatus$
(RxJS) Observable returns details of quality status of the current frame.
In real time process (during video)
qualityStatus$
returns information about current processed frame.After taking photo,
qualityStatus$
returns information about final image quality. N.B.! This option is available since5.4.0
version.

See the Integration Guideline and Stream results parsing for a usage example of an observable.
events$: Observable<number>
The events$
(RxJS) Observable returns status of important LIQA statuses.
See the Parsing guidelines for example of events parsing.
selfieImage$: Observable<string>
The selfieImage$
(RxJS) Observable returns base64
code of photo.
See the Integration Guideline and Selfie capturing results parsing for a usage example of an observable.
selfieLandmarks$: Observable<Array<number>>
The selfieLandmarks$
(RxJS) Observable returns an array of 53 points (vertices) with (X, Y, depth) coordinates, aligned in pixels with a returned selfie image.
See the Integration Guideline and Selfie capturing results parsing for a usage example of an observable.
