  • hierophantically — In a hierophantic manner; in the manner of a hierophant.
  • high-compression — of a modern type of internal-combustion engine designed so that the fuel mixture is compressed into a smaller cylinder space, resulting in more pressure on the pistons and more power
  • high-performance — A high-performance car or other product goes very fast or does a lot.
  • hispano-american — Spanish.
  • hospital corners — a fold on a bed sheet or blanket made by tucking the foot or head of the sheet straight under the mattress with the ends protruding and then making a diagonal fold at the side corner of the sheet and tucking this under to produce a triangular corner.
  • hospital service — the whole organization of government funded hospitals, their staff, and the services they provide

  • hypercorrections — Plural form of hypercorrection.
  • ice-cream parlor — an establishment serving ice cream, sodas, etc., from a soda fountain.
  • image processing — (graphics)   Computer manipulation of images. Some of the many algorithms used in image processing include convolution (on which many others are based), FFT, DCT, thinning (or skeletonisation), edge detection and contrast enhancement. These are usually implemented in software but may also use special purpose hardware for speed. Image processing contrasts with computer graphics, which is usually more concerned with the generation of artificial images, and visualisation, which attempts to understand (real-world) data by displaying it as an artificial image (e.g. a graph). Image processing is used in image recognition and computer vision. See also Pilot European Image Processing Archive.

  • lz77 compression — The first algorithm to use the Lempel-Ziv substitutional compression schemes, proposed in 1977. LZ77 compression keeps track of the last n bytes of data seen, and when a phrase is encountered that has already been seen, it outputs a pair of values corresponding to the position of the phrase in the previously-seen buffer of data, and the length of the phrase. In effect the compressor moves a fixed-size "window" over the data (generally referred to as a "sliding window"), with the position part of the (position, length) pair referring to the position of the phrase within the window. The most commonly used algorithms are derived from the LZSS scheme described by James Storer and Thomas Szymanski in 1982. In this the compressor maintains a window of size N bytes and a "lookahead buffer", the contents of which it tries to find a match for in the window: while (lookAheadBuffer not empty) { get a pointer (position, match) to the longest match in the window for the lookahead buffer; if (length > MINIMUM_MATCH_LENGTH) { output a (position, length) pair; shift the window length characters along; } else { output the first character in the lookahead buffer; shift the window 1 character along; } } Decompression is simple and fast: whenever a (POSITION, LENGTH) pair is encountered, go to that POSITION in the window and copy LENGTH bytes to the output. Sliding-window-based schemes can be simplified by numbering the input text characters mod N, in effect creating a circular buffer. The sliding window approach automatically creates the LRU effect which must be done explicitly in LZ78 schemes. Variants of this method apply additional compression to the output of the LZSS compressor, which include a simple variable-length code (LZB), dynamic Huffman coding (LZH), and Shannon-Fano coding (ZIP 1.x), all of which result in a certain degree of improvement over the basic scheme, especially when the data are rather random and the LZSS compressor has little effect. An algorithm was developed which combines the ideas behind LZ77 and LZ78 to produce a hybrid called LZFG. LZFG uses the standard sliding window, but stores the data in a modified trie data structure and produces as output the position of the text in the trie. Since LZFG only inserts complete *phrases* into the dictionary, it should run faster than other LZ77-based compressors. All popular archivers (arj, lha, zip, zoo) are variations on LZ77.
  • lz78 compression — A substitutional compression scheme which works by entering phrases into a dictionary and then, when a reoccurrence of that particular phrase is found, outputting the dictionary index instead of the phrase. Several algorithms are based on this principle, differing mainly in the manner in which they manage the dictionary. The most well-known Lempel-Ziv scheme is Terry Welch's Lempel-Ziv Welch variant of LZ78.
