GET
Returns the binary segmentation mask for each featurized frame of a processed RHEED video, encoded using run-length encoding (RLE) in the same COCO format as the single-image mask. frame_number is the absolute frame index, keyed identically to the processed video frames and to the Frame Number axis of the RHEED timeseries, so a decoded mask overlays the matching frame of the processed video.
Coverage is sparse. Masks exist only for featurized frames: every frame for stationary videos, but only the sampled subset for rotating and per-azimuth videos. Frames without a mask are absent from the response rather than returned as null.
string
required
The data entry UUID of the RHEED video, the same ID used for the video and timeseries
integer
default:"0"
First absolute frame number to return, inclusive
integer
Last absolute frame number to return, inclusive. Omit to return every featurized frame from from onward

Response

Returns an array of mask records.
string
Data entry UUID
string
Processed data entry UUID
integer
Absolute frame index within the video
string
Run-length encoded mask data, column-major (Fortran order)
integer
Height of the mask in pixels
integer
Width of the mask in pixels
A 404 means the video has no per-frame mask artifact, either because the item is not RHEED or because it was processed before per-frame masks were persisted.
