millisecond repeat image filter with Photo gallery 毫秒级图片库去重， 去重效率与图片库数量无关，0.1~10ms
- 实现算法思路
1.多线程提取图片的hash值；
2.hash转化成32~64位长索引值, 在信息库中顺序查找索引，相同索引为重复图；
3.如无重复，将提取图片信息按索引顺序插入信息库；
- requirement:
cv2
PIL
concurrent
imagehash or use my phash only
- 图片信息保存的信息库
image_infobase.json
{"info_base": [[hash_index, image_path], ...]}
信息库大小会影响读写时的速度，基本不影响查找时间。
