market1501的图片命名信息,以图片 0012_c4s1_000826_01.jpg 对数据集命名进行说明
DPM 检测器是DPM 是一种基于部件的模型,它将目标(如行人)视为多个部分的组合,这些部分可以有不同的形状和大小,并且它们之间的相对位置可以变形。例如在行人检测中,部件可能包括头部、手臂、躯干、腿等。这些部件被建模为滤波器,用于在图像中搜索与之对应的特征。
数据集的文件格式分析
下载好的 Market 1501 包括以下几个文件夹:
因此,我们只需要创建几个文件夹-bounding_box_test 、bounding_box_train和query。使用的代码如下:
import os
def make_market_dir(dst_dir='./'):
market_root = os.path.join(dst_dir, 'market1501')
train_path = os.path.join(market_root, 'bounding_box_train')
query_path = os.path.join(market_root, 'query')
test_path = os.path.join(market_root, 'bounding_box_test')
if not os.path.exists(train_path):
os.makedirs(train_path)
if not os.path.exists(query_path):
os.makedirs(query_path)
if not os.path.exists(test_path):
os.makedirs(test_path)
if __name__ == '__main__':
make_market_dir(dst_dir='E:/reID')
