+# model input and output
+det_input_size = (736, 736) # (model height, model width)
+rec_input_size = ( 48, 320) # (model height, model width)
+rec_output_size = (40, 97) # rec output
+```
+```python postprocess.py
+character_str = ["blank"]
+with open("./data/ppocr_keys_v1.txt", "rb") as fin: # the path for character index dictionary
+    lines = fin.readlines()
+    for line in lines:
+        line = line.decode("utf-8").strip("\n").strip("\r\n")
+        character_str.append(line)
+character_str.append(" ")
+ignored_token = [0]
