Get processed sample (from features array)

Get processed sample (from features array)

Takes in a features array and runs it through the DSP block. This data should have the same frequency as set in the input block in your impulse.

POSThttps://studio.edgeimpulse.com/v1/api/{projectId}/dsp/{dspId}/run

Path parameters

projectId*integer

Project ID

dspId*integer

DSP Block ID, use the impulse functions to retrieve the ID

Body

application/json

features*array of integer

Array of features. If you have multiple axes the data should be interleaved (e.g. [ax0_val0, ax1_val0, ax2_val0, ax0_val1, ax1_val1, ax2_val1]).

params*object

DSP parameters with values

drawGraphs*boolean

Whether to generate graphs (will take longer)

requestPerformance*boolean

Whether to request performance info (will take longer unless cached)

Response

200

OK

Body

application/json

success*boolean

Whether the operation succeeded

errorstring

Optional error description (set if 'success' was false)

features*array of number

Array of processed features. Laid out according to the names in 'labels'

graphs*array of DspRunGraph (object)

Graphs to plot to give an insight in how the DSP process ran

labelsarray of string

Labels of the feature axes

state_stringstring

String representation of the DSP state returned

performanceobject
