Key Differences
A pixel, short for "picture element," is the basic unit of programmable color on a digital display or a digital image, whereas a mixel refers to a mixed pixel that occurs in multi-spectral imaging when different materials or features are contained within one pixel area.
Pixels are crucial for defining the resolution and quality of images and videos; each pixel displays a specific color formed by the combination of red, green, and blue subpixels. On the other hand, mixels complicate the interpretation of spectral data because they blend the spectral signatures of multiple materials.
In digital photography and computer graphics, pixels are manipulated to create and enhance images. Conversely, mixels often pose challenges in remote sensing applications, requiring specialized algorithms to resolve mixed spectral signals.
The concept of a pixel is foundational across all digital displays and image sensors, serving as the building block for visual representation. Mixels, however, are more specific to the field of remote sensing and spectral analysis, where precise material identification is necessary.
Pixel technology focuses on advancements in resolution and color accuracy, enhancing visual media experiences. Mixels, in contrast, are the focus of ongoing research aimed at improving the accuracy of environmental monitoring and resource mapping.

Pixel
In digital imaging, a pixel, pel, or picture element is a smallest addressable element in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original.
Mixel
(geographical sciences) In field-based conceptualisation, a raster cell which indicates elements of mixed or multiple land cover categories.
Pixel
The basic unit of a digital image, representing a single color or level of brightness.
Pixel
One of the tiny dots that make up the representation of an image in a computer's memory.
Pixel
One of the squares that make up a pixel art work or a zoomed in image in a computer.
Pixel
To create computer graphics by editing individual pixels.
Pixel
(computer science) the smallest discrete component of an image or picture on a CRT screen (usually a colored dot);
The greater the number of pixels per inch the greater the resolution
