  2. Normalization (image processing) - Wikipedia

    en.wikipedia.org/wiki/Normalization_(image...

    A Contrast Stretching Transformation can be achieved by: Contrast Stretching Transformation Graph reference for derivation. 1. Stretching the dark range of input values into a wider range of output values: This involves increasing the brightness of the darker areas in the image to enhance details and improve visibility. 2.

  3. Kernel (image processing) - Wikipedia

    en.wikipedia.org/wiki/Kernel_(image_processing)

    Normalization is defined as the division of each element in the kernel by the sum of all kernel elements, so that the sum of the elements of a normalized kernel is unity. This will ensure the average pixel in the modified image is as bright as the average pixel in the original image.

  4. Adaptive histogram equalization - Wikipedia

    en.wikipedia.org/wiki/Adaptive_histogram...

    Adaptive histogram equalization (AHE) is a computer image processing technique used to improve contrast in images. It differs from ordinary histogram equalization in the respect that the adaptive method computes several histograms, each corresponding to a distinct section of the image, and uses them to redistribute the lightness values of the image.

  5. Normal form (abstract rewriting) - Wikipedia

    en.wikipedia.org/wiki/Normal_form_(abstract...

    The system {b → a, b → c, c → b, c → d} (pictured) is an example of a weakly normalizing but not strongly normalizing system. a and d are normal forms, and b and c can be reduced to a or d, but the infinite reduction b → c → b → c → ... means that neither b nor c is strongly normalizing.

  6. Normalization (machine learning) - Wikipedia

    en.wikipedia.org/wiki/Normalization_(machine...

    Instance normalization (InstanceNorm), or contrast normalization, is a technique first developed for neural style transfer, and is also only used for CNNs. [26] It can be understood as the LayerNorm for CNN applied once per channel, or equivalently, as group normalization where each group consists of a single channel:

  7. Clip coordinates - Wikipedia

    en.wikipedia.org/wiki/Clip_coordinates

    The clip coordinate system is a homogeneous coordinate system in the graphics pipeline that is used for clipping. [1]Objects' coordinates are transformed via a projection transformation into clip coordinates, at which point it may be efficiently determined on an object-by-object basis which portions of the objects will be visible to the user.

  8. Color normalization - Wikipedia

    en.wikipedia.org/wiki/Color_normalization

    There is a vast array of different transformations and algorithms for achieving color normalization and a limited list is presented here. The performance of an algorithm is dependent on the task and one algorithm which performs better than another in one task might perform worse in another (no free lunch theorem). Additionally, the choice of ...

  9. Mesh generation - Wikipedia

    en.wikipedia.org/wiki/Mesh_generation

    The simplest procedure that may be used to produce boundary fitted computational mesh is the normalization transformation. [ 1 ] For a nozzle, with the describing function y = x 2 {\displaystyle y=x^{2}} the grid can easily be generated using uniform division in y -direction with equally spaced increments in x -direction, which are described by
