Что (кто) такое progressive coding - определение

<graphics, file format, algorithm> (Or "interlacing") An aspect of a graphics storage format or transmission algorithm that treats bitmap image data non-sequentially in such a way that later data adds progressively greater resolution to an already full-size image. This contrasts with sequential coding. Progressive coding is useful when an image is being sent across a slow communications channel, such as the Internet, as the low-resolution image may be sufficient to allow the user to decide not to wait for the rest of the file to be received. In an interlaced GIF89 image, the pixels in a row are stored sequentially but the rows are stored in interlaced order, e.g. 0, 8, 4, 12, 2, 6, 8, 10, 14, 1, 3, 5, 7, 9, 11, 13, 15. Each vertical scan adds rows in the middle of the gaps left by the previous one. PNG interlaces both horizontally and vertically using the "Adam7" method, a seven pass process named after Adam M. Costello. Interlacing is also supported by other formats. JPEG supports a functionally similar concept known as {Progressive JPEG}. [How does the algorithm differ?] JBIG uses progressive coding.

The coding region of a gene, also known as the coding sequence (CDS), is the portion of a gene's DNA or RNA that codes for protein. Studying the length, composition, regulation, splicing, structures, and functions of coding regions compared to non-coding regions over different species and time periods can provide a significant amount of important information regarding gene organization and evolution of prokaryotes and eukaryotes.

Progressive music is music that attempts to expand existing stylistic boundaries associated with specific genres of music.; ; The word comes from the basic concept of "progress", which refers to advancements through accumulation, and is often deployed in the context of distinct genres, with progressive rock being the most notable example.
