What is the difference between a pixel and a voxel?

Pixels and voxels are each essential units of dimension in digital imaging and pc pics, however they're used in exclusive contexts and constitute one-of-a-kind dimensions of information. Here's the important thing difference between them:

  1. Pixel (Picture Element):

    • A pixel is the smallest discrete unit of a digital picture, generally in 2D (-dimensional) space, such as on a pc display screen or in a image.
    • It represents a unmarried point in a 2D grid and is defined by means of its position, color, and brightness.
    • Pixels are used to represent snap shots and visible statistics in a flat, planar format. They are normally used in pictures, virtual displays, and photo processing.
  2. Voxel (Volume Element):

    • A voxel is the equivalent of a pixel but in 3-d (three-dimensional) area. It represents a factor in a 3-D grid and adds the 0.33 dimension, that's depth or quantity.
    • Voxel facts consists of no longer most effective coloration and brightness statistics (like pixels) however also records about the extent and density of the cloth at that point in 3-d space.
    • Voxels are used in fields along with clinical imaging (CT and MRI scans), three-D laptop photographs, and clinical visualization, where information approximately items' internal structures or residences in three-D area is required.

In summary, pixels are used in 2D digital imaging, representing factors on a flat surface, whilst voxels are used in 3-D programs to symbolize factors inside a volume, imparting extra depth and spatial information. Both pixels and voxels function building blocks for virtual representations, but the preference between them depends on the dimensionality and the unique necessities of the facts or application.
