需要先建立索引
import osimport hashlibfrom elasticsearch import Elasticsearch, ConnectionError, RequestError, NotFoundErrorfrom image_match.elasticsearch_driver import SignatureESDOC_TYPE = 'image'MAPPINGS = { "mappings": { DOC_TYPE: { "dynamic": True, "properties": { "metadata": { "type": "object", "dynamic": True, "properties": { "tenant_id": { "type": "string", "index" : "not_analyzed" } } } } } }}def setup_index(): es = Elasticsearch() try: es.indices.create(index="images", body=MAPPINGS) except RequestError as e: if e.error == u'index_already_exists_exception': es.indices.delete(index_name) else: raisesetup_index()然后dump数据
from elasticsearch import Elasticsearchfrom image_match.elasticsearch_driver import SignatureESes = Elasticsearch()ses = SignatureES(es)ses.add_image('https://upload.wikimedia.org/wikipedia/commons/thumb/e/ec/Mona_Lisa,_by_Leonardo_da_Vinci,_from_C2RMF_retouched.jpg/687px-Mona_Lisa,_by_Leonardo_da_Vinci,_from_C2RMF_retouched.jpg')ses.add_image('https://pixabay.com/static/uploads/photo/2012/11/28/08/56/mona-lisa-67506_960_720.jpg')ses.add_image('https://upload.wikimedia.org/wikipedia/commons/e/e0/Caravaggio_-_Cena_in_Emmaus.jpg')ses.add_image('https://c2.staticflickr.com/8/7158/6814444991_08d82de57e_z.jpg')索引结果如下
然后进行检索
ses.search_image('https://pixabay.com/static/uploads/photo/2012/11/28/08/56/mona-lisa-67506_960_720.jpg')
返回结果如下， dist越小越好。
