About this app (See raw metadata.json)
Stitches a sequence of TimePoint
annotations into a sequence of TimeFrame
annotations, performing simple smoothing of short peaks of positive labels.

Inputs
(Note: “*” as a property value means that the property is required but can be any value.)
One of the following is required: [
-
http://mmif.clams.ai/vocabulary/AudioDocument/v1 (required) (of any properties)
-
http://mmif.clams.ai/vocabulary/VideoDocument/v1 (required) (of any properties)
]
- http://mmif.clams.ai/vocabulary/TimePoint/v4 (required)
- timePoint = “*”
- classification = “*”
TimePoint annotations to be stitched. Must be “exhaustive” in that it should cover an entire single time period in the input document, with a uniform sample rate.
Configurable Parameters
(Note: Multivalued means the parameter can have one or more values.)
-
labelMap
: optional, defaults to[]
- Type: map
- Multivalued: True
mapping of labels in the input annotations to new labels. Must be formatted as “IN_LABEL:OUT_LABEL” (with a colon). To pass multiple mappings, use this parameter multiple times. By default, all the input labels are passed as is, including any “negative” labels (with default value being no remapping at all). However, when at least one label is remapped, all the other “unset” labels are discarded as the negative label(“-“).
-
minTFDuration
: optional, defaults to1000
- Type: integer
- Multivalued: False
minimum duration of a TimeFrame in milliseconds
-
minTPScore
: optional, defaults to0.1
- Type: number
- Multivalued: False
minimum score of a TimePoint to be considered as positive
-
minTFScore
: optional, defaults to0.5
- Type: number
- Multivalued: False
minimum average score of TimePoints in a TimeFrame to be considered as positive
-
labelMapPreset
: optional, defaults tonull
- Type: string
- Multivalued: False
- Choices:
null
,swt-v4-4way
,swt-v4-6way
preset of label mappings. If not
null
, this parameter will override thelabelMap
parameter. Available presets are:
-null

:['B:bars', 'S:slate', 'I:chyron', 'N:chyron', 'Y:chyron', 'C:credits', 'R:credits']

false
,true
The JSON body of the HTTP response will be re-formatted with 2-space indentation
Outputs
(Note: “*” as a property value means that the property is required but can be any value.)
(Note: Not all output annotations are always generated.)
- http://mmif.clams.ai/vocabulary/TimeFrame/v5
- timeUnit = “milliseconds”
- label = “*”
- representatives = “*”
Stitched TimeFrame annotations. Each TimeFrame annotation represents a continuous segment of timepoints and its
label
property is determined by thelabelMap
parameter (seeparameters
section). Therepresentatives
is a singleton list of the TimePoint annotation that has the highest score in the TimeFrame.
