Introduction Recently, during a penetration test for a client, I discovered a peculiar SQL injection. It was peculiar because the database connection encoding of the system was inconsistent with the actual database encoding, and the database table field names used Chinese characters, making it impossible to retrieve database data through normal means. The Story Begins … Read more
Accurately identifying human eyes and locating their positions is crucial for numerous applications. From identity verification in security monitoring to gaze tracking in human-computer interaction, reliable human eye recognition technology is indispensable. The following code demonstrates a process for human eye recognition and position marking using MATLAB. Estimated reading time: 5 minutes. 1. Code %% … Read more
