# CASIA-B\*
|
|
## Introduction
|
|
CASIA-B\* is a re-segmented version of CASIA-B processed by Liang et al. The extra import of CASIA-B* owes to the background subtraction algorithm that CASIA-B uses for generating the silhouette data tends to produce much noise and is outdated for real-world applications nowadays. We use the up-to-date pretreatment strategy to re-segment the raw videos, i.e., the deep pedestrian track and segmentation algorithms. As a result, CASIA-B\* consists of the cropped RGB images, binary silhouettes, the height-width ratio of the obtained bounding boxes and the aligned silhouettes. Please refer to [GaitEdge](../../configs/gaitedge/README.md) for more details. If you need this sub-set, please apply with the instruction mentioned in [http://www.cbsr.ia.ac.cn/english/Gait%20Databases.asp]. In the Email Subject, please mark the specific dataset you need, i.e., Dataset B*.

## How to use
|
|
By default, it loads all file directory information like other datasets before training starts. If you need to use some of these data separately, such as `aligned-sils`, then you can use the `data_in_use` parameter in `data_cfg` lexicographically, *i.e.* `data_in_use: [true, false, false, false]`.
