  2. Chroma subsampling - Wikipedia

    en.wikipedia.org/wiki/Chroma_subsampling

    The mapping examples given are only theoretical and for illustration. Also the diagram does not indicate any chroma filtering, which should be applied to avoid aliasing. To calculate required bandwidth factor relative to 4:4:4 (or 4:4:4:4), one needs to sum all the factors and divide the result by 12 (or 16, if alpha is present).

  3. Rec. 601 - Wikipedia

    en.wikipedia.org/wiki/Rec._601

    ITU-R Recommendation BT.601, more commonly known by the abbreviations Rec. 601 or BT.601 (or its former name CCIR 601), is a standard originally issued in 1982 by the CCIR (an organization, which has since been renamed as the International Telecommunication Union – Radiocommunication sector) for encoding interlaced analog video signals in digital video form.

  4. Y′UV - Wikipedia

    en.wikipedia.org/wiki/Y′UV

    The scope of the terms Y′UV, YUV, YCbCr, YPbPr, etc., is sometimes ambiguous and overlapping. Y′UV is the separation used in PAL.; YDbDr is the format used in SECAM and PAL-N, unusually based on non-gamma-corrected (linear) RGB, making the Y component true luminance.

  5. A foolproof guide to image manipulation in Python with OpenCV

    OpenCV is a huge image and video processing library designed to work with many languages such as python, C/C++, Java, and more. It is the foundation for many of the applications you know that deal ...

  6. Binary translation - Wikipedia

    en.wikipedia.org/wiki/Binary_translation

    Dynamic binary translation (DBT) looks at a short sequence of code—typically on the order of a single basic block—then translates it and caches the resulting sequence. Code is only translated as it is discovered and when possible, and branch instructions are made to point to already translated and saved code (memoization).

  7. RGB color spaces - Wikipedia

    en.wikipedia.org/wiki/RGB_color_spaces

    The primary colors are usually mapped to xyY chromaticity coordinates, though the uʹ,vʹ coordinates from the UCS chromaticity diagram may be used. Both xyY and uʹ,vʹ are derived from the CIE 1931 color space , a device independent space also known as XYZ which covers the full gamut of human-perceptible colors visible to the CIE 2° standard ...

  8. Ut Video Codec Suite - Wikipedia

    en.wikipedia.org/wiki/Ut_Video_Codec_Suite

    UT Video Codec Suite is a fast, lossless video codec, developed by Takeshi Umezawa (梅澤 威志, Umezawa Takeshi) and released under the free GNU General Public License. The algorithm of UT video is based on the Huffman code. UT video was developed as an alternative to HuffYUV, in order to achieve better compression.

  9. Bundle adjustment - Wikipedia

    en.wikipedia.org/wiki/Bundle_adjustment

    A sparse matrix obtained when solving a modestly sized bundle adjustment problem. This is the arrowhead sparsity pattern of a 992×992 normal-equation (i.e. approximate Hessian) matrix.
