+    filtertype='Regular',
+    thresh=0.05,
+    blur='None',
+    norm=np.inf,

+
+Compute Self-Similarity Matrix (SSM) by converting the input signal into a suitable feature sequence and comparing each element of the feature sequence with all other elements of the sequence.
+SSMs can be computed over different input features such as 'motiongrams', 'spectrogram', 'chromagram' and 'tempogram'.
+
+#### Arguments
+
+- `features` *str, optional* - Defines the type of features on which to compute SSM. Possible to compute SSM on 'motiongrams', 'spectrogram', 'chromagram' and 'tempogram'. Defaults to 'motiongrams'.
+- `filtertype` *str, optional* - 'Regular' turns all values below `thresh` to 0. 'Binary' turns all values below `thresh` to 0, above `thresh` to 1. 'Blob' removes individual pixels with erosion method. Defaults to 'Regular'.
+- `thresh` *float, optional* - Eliminates pixel values less than given threshold. Ranges from 0 to 1. Defaults to 0.05.
+- `blur` *str, optional* - 'Average' to apply a 10px * 10px blurring filter, 'None' otherwise. Defaults to 'None'.
+- `norm` *int, optional* - Normalize the columns of the feature sequence. Possible to compute Manhattan norm (1), Euclidean norm (2), Minimum norm (-np.inf), Maximum norm (np.inf), etc. Defaults to np.inf.
+- `threshold` *float, optional* - Only the columns with norm at least the amount of `threshold` indicated are normalized. Defaults to 0.001.
+- `cmap` *str, optional* - A Colormap instance or registered colormap name. The colormap maps the C values to colors. Defaults to 'gray_r'.
+- `use_median` *bool, optional* - If True the algorithm applies a median filter on the thresholded frame-difference stream. Defaults to False.
+- `kernel_size` *int, optional* - Size of the median filter (if `use_median=True`) or the erosion filter (if `filtertype='blob'`). Defaults to 5.
+- `target_name` *[type], optional* - Target output name for the SSM. Defaults to None.
+- `overwrite` *bool, optional* - Whether to allow overwriting existing files or to automatically increment target filenames to avoid overwriting. Defaults to False.
+
+#### Returns
+
+# if features='motiongrams':
+- `MgList` - An MgList pointing to the output SSM images (as MgImages).
+# else:
+- `MgImage` - An MgImage to the output SSM.

+):
+```
+
+Smoothes and downsamples a feature sequence. Smoothing is achieved by convolution with a filter kernel
+
+#### Arguments
+
+- `X` *np.ndarray* - Feature sequence.
+- `sr` *int* - Sampling rate.
+- `filt_len` *int, optional* - Length of smoothing filter. Defaults to 41.
+- `down_sampling` *int, optional* - Downsampling factor. Defaults to 10.
+- `w_type` *str, optional* - Window type of smoothing filter. Defaults to 'boxcar'.
+
+#### Returns
+
+- `X_smooth` *np.ndarray* - Smoothed and downsampled feature sequence.
+- `sr_feature` *scalar* - Sampling rate of `X_smooth`.
