High performance reversible data hiding for block truncation coding compressed images

Reversible data hiding has been a hot research topic because it can recover both the host media and hidden data without distortion. Because most digital images are stored and transmitted in compressed forms, such as JPEG, vector quantization, and block truncation coding (BTC), the reversible data hiding schemes in compressed domains have been paid more and more attention. Compared with transform coding, BTC has a significantly low complexity and less memory requirement, it therefore becomes an i

这个错误通常表示在插入或更新数据库中的数据时，'code_student' 列的数据长度超过了列的最大长度限制。请确保你要插入或更新的数据在 'code_student' 列中的长度不超过列的定义。你可以检查数据库表结构中 'code_student' 列的定义，并相应地调整数据的长度或更改列的定义以适应更长的数据。
