Character restoration method and apparatus, storage medium, and electronic device

A character restoration method, comprising:

• receiving and decoding encoded data to at least obtain a character identifier of a character in a text region, wherein the character identifier is used for uniquely identifying the character;
• and
• restoring the character according to the character identifier obtained after decoding;
• wherein the character identifier is an index of a character feature of the character in preset character feature information, wherein the character feature comprises a character height of the character, a character width of the character, and a character pixel matrix distribution of the character;
• wherein the index of the character feature of the character in the preset character feature information is determined in a following way:
• performing matching in specified character features in the character feature information according to the character feature of the character until a complete character feature of the character is matched, wherein the specified character features comprise:
• character features with a height the same as the character height of the character, a width greater than or equal to the character width of the character, and a pixel matrix distribution the same as the character pixel matrix distribution of the character;
• and
• determining the index of the complete character feature in the character feature information according to the matched complete character feature.

A character restoration system, comprising:

• a sending end and a receiving end, wherein the sending end is configured to perform, after determining a character identifier of a character in a text region, encoding at least according to the character identifier, and send encoded data to the receiving end, wherein the character identifier is used for uniquely identifying the character;
• the receiving end is configured to decode the encoded data and restore the character according to the character identifier obtained after decoding;
• wherein the sending end is also configured to perform, extracting a character feature of the character in the text region, wherein the character feature comprises a character height of the character, a character width of the character, and a character pixel matrix distribution of the character;
• and
• performing matching in preset character feature information according to the character feature, determining an index of the character feature of the character in the character feature information, and taking the index of the character feature as the character identifier;
• wherein the sending end is also configured to perform, performing matching in specified character features in the character feature information according to the character feature of the character until a complete character feature of the character is matched, wherein the specified character features comprise:
• character features with a height the same as the character height of the character, a width greater than or equal to the character width of the character, and a pixel matrix distribution the same as the character pixel matrix distribution of the character;
• and
• determining the index of the complete character feature in the character feature information according to the matched complete character feature.
