METHOD AND APPARATUS FOR ENCODING AND DECODING IMAGE BY USING ROTATIONAL TRANSFORM |
摘要 |
<p>An image encoding method includes generating a first frequency coefficient matrix by transforming a predetermined block to a frequency domain; determining whether the first frequency coefficient matrix includes coefficients whose absolute values are greater than a predetermined value; generating a second frequency coefficient matrix by selectively partially switching at least one of rows and columns of the first frequency coefficient matrix according to an angle parameter based on a determination result; and selectively encoding the second frequency coefficient matrix based on the determination result.</p> |
