  2. Lossless compression - Wikipedia

    en.wikipedia.org/wiki/Lossless_compression

    An obvious way of detection is applying a raw compression algorithm and testing if its output is smaller than its input. Sometimes, detection is made by heuristics; for example, a compression application may consider files whose names end in ".zip", ".arj" or ".lha" uncompressible without any more sophisticated detection. A common way of ...

    On the previous example, this would give the following: WW12BWW12BB3WW24BWW14. This would be interpreted as a run of twelve Ws, a B, a run of twelve Ws, a run of three Bs, etc. In data where runs are less frequent, this can significantly improve the compression rate. One other matter is the application of additional compression algorithms.

  4. GIF - Wikipedia

    For identical 8-bit (or lower) image data, PNG files are typically smaller than the equivalent GIFs, due to the more efficient compression techniques used in PNG encoding. [62] Complete support for GIF is complicated chiefly by the complex canvas structure it allows, though this is what enables the compact animation features.

  5. Lossy compression - Wikipedia

    en.wikipedia.org/wiki/Lossy_compression

    While data reduction (compression, be it lossy or lossless) is a main goal of transform coding, it also allows other goals: one may represent data more accurately for the original amount of space [5] – for example, in principle, if one starts with an analog or high-resolution digital master, an MP3 file of a given size should provide a better ...

  6. Peer support - Wikipedia

    en.wikipedia.org/wiki/Peer_support

    Peer support can occur within, outside or around traditional mental health services and programs, between two people or in groups. Peer support is increasingly being offered through digital health like text messaging and smartphone apps. [31] Peer support is a key concept in the recovery approach [32] and in consumer-operated services programs ...

  7. Image file format - Wikipedia

    en.wikipedia.org/wiki/Image_file_format

    For example, graphically simple images (i.e. images with large continuous regions like line art or animation sequences) may be losslessly compressed into a GIF or PNG format and result in a smaller file size than a lossy JPEG format. For example, a 640 × 480 pixel image with 24-bit color would occupy almost a megabyte of space: 640 × 480 × ...

    As an example consider the sequence of tokens AABBA which would assemble the dictionary; 0 {0,_} 1 {0,A} 2 {1,B} 3 {0,B} and the output sequence of the compressed data would be 0A1B0B. Note that the last A is not represented yet as the algorithm cannot know what comes next. In practice an EOF marker is added to the input – AABBA$ for
