 Implemement of DEEP SUPERVISED HASHING FOR FAST IMAGE RETRIEVAL_CVPR2016
 
 
-Train:
-    python demo.py
-    First you need to modify demo.py to ensure TRAIN=True,and you can modify HASHING_BITS to generate any length hashing bit.
-	After training, in dir /logs will save trained model.
+## Train: 
+`python demo.py`
 
-Test:
-    After training, you can change TRAIN=False,then run python.demo.py,result.txt will be generated.
