An impulse takes raw data, uses signal processing to extract features, and then uses a learning
block to classify new data.

| Description | Recommended | |
|---|---|---|
Images
Processes discrete images for object detection or classification.
|
||
Time series data
Operates on time series sensor data like vibration or audio data. Lets you slice up data into windows.

|---|---|---|---|
Image
Preprocess and normalize image data, and optionally reduce the color depth.

Edge Impulse | ||
Flatten
Flatten an axis into a single value, useful for slow-moving averages like temperature data, in combination with other blocks.
|
Edge Impulse | ||
Audio (MFCC)
Extracts features from audio signals using Mel Frequency Cepstral Coefficients, great for human voice.
|
Edge Impulse | ||
Audio (MFE)
Extracts a spectrogram from audio signals using Mel-filterbank energy features, great for non-voice audio.
|
Edge Impulse | ||
Spectral Analysis
Great for analyzing repetitive motion, such as data from accelerometers. Extracts the frequency and power characteristics of a signal over time.
|
Edge Impulse | ||
Spectrogram
Extracts a spectrogram from audio or sensor data, great for non-voice audio or data with continuous frequencies.
|
Edge Impulse | ||
Audio (Syntiant)
Syntiant only. Compute log Mel-filterbank energy features from an audio signal.
|
Syntiant | ||
IMU (Syntiant)
Syntiant only. Great for analyzing repetitive motion, such as data from accelerometers. Extracts the frequency and power characteristics of a signal over time.
|
Syntiant | ||
Raw Data
Use data without pre-processing. Useful if you want to use deep learning to learn features.
|
Edge Impulse |
Some processing blocks have been hidden based on the data in your project.
