python-----图像去重（imagededup）

安装库：

pip install imagededup

安装可能遇到的问题参考：

Cannot uninstall 'wrapt'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

ipython 6.5.0 has requirement prompt-toolkit<2.0.0,>=1.0.15, but you'll have prompt-toolkit 2.0.15 which is incompatible.

代码如下：

from imagededup.methods import PHash
phasher = PHash()

if __name__ == '__main__':
    # 生成图像目录中所有图像的二值hash编码
    encodings = phasher.encode_images(image_dir=r'F:	emp	emp_1010JPEGImages')

    # 对已编码图像寻找重复图像
    duplicates = phasher.find_duplicates(encoding_map=encodings)
    print('='*20)
    print(duplicates)
    print(type(duplicates))
    print('='*20)

    # 给定一幅图像，显示与其重复的图像
    from imagededup.utils import plot_duplicates
    plot_duplicates(image_dir=r'F:	emp	emp_1010JPEGImages',
                    duplicate_map=duplicates,
                    filename='0000128.jpg')

显示结果如下：

 运行可能遇到的问题参考：

An attempt has been made to start a new process before the
        current process has finished its bootstrapping phase.

        This probably means that you are not using fork to start your
        child processes and you have forgotten to use the proper idiom
        in the main module:
