• Extracting silhouettes from OutdoorGait-img using GaitPretreatment. (including RVM, Clean, and Augment)

python OutdoorGait.py

Parameters

img_size: Image resizing size. Default 64.

clean: Clean up the unqualified silhouettes using a silhouette classification model. Default True.

augment: Flip the cleaned silhouette sequence horizontally for data augmentation. Default True.

frame_resize_threshold: When using RVM preprocessing, in order to speed up the silhouette extraction, images larger than the width of threshold pixels will be scaled to threshold pixels. Default 800 pixels.

pixel_threshold: The threshold for finding the upper and lower boundaries of a person when cutting images. (the sum of row pixels is greater than or equal to the threshold pixel). Default 800 pixels.
