This is done in order to guarantee that a desired quality (fixed in advance using the well known&amp;nbsp;&lt;em&gt;PSNR&lt;/em&gt;&amp;nbsp;metric) is checked. For the aim to obtain the best possible&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/engineering/compression-ratio&quot; title=&quot;Learn more about Compression Ratio from ScienceDirect's AI-generated Topic Pages&quot;&gt;compression ratio&lt;/a&gt;&amp;nbsp;&lt;em&gt;CR&lt;/em&gt;, the next step is the application of a proposed adaptive scanning providing, for each (&lt;em&gt;n&lt;/em&gt;,&amp;nbsp;&lt;em&gt;n&lt;/em&gt;) DCT block a corresponding (&lt;em&gt;n&lt;/em&gt;×&lt;em&gt;n&lt;/em&gt;) vector containing the maximum possible run of zeros at its end.

The efficiency of the proposed scheme is demonstrated by results, especially, when faced to the method presented in the recently published paper based on the&amp;nbsp;&lt;a href=&quot;https://www.sciencedirect.com/topics/computer-science/block-truncation-coding&quot; title=&quot;Learn more about Block Truncation Coding from ScienceDirect's AI-generated Topic Pages&quot;&gt;block truncation coding&lt;/a&gt;&amp;nbsp;using pattern fitting principle.</style></abstract><issue><style face="normal" font="default" size="100%">01</style></issue></record></records></xml>
