  2. Comparative anatomy - Wikipedia

    en.wikipedia.org/wiki/Comparative_anatomy

    Comparative anatomy studies similarities and differences in organisms. The image shows homologous bones in the upper limb of various vertebrates. Comparative anatomy is the study of similarities and differences in the anatomy of different species. It is closely related to evolutionary biology and phylogeny [1] (the evolution of species).

  3. Visual comparison - Wikipedia

    en.wikipedia.org/wiki/Visual_comparison

    This invokes deep, fast, built-in image comparison wetware (the same machinery responsible for depth perception) and differences stand out almost immediately. This technique is good for finding edits in graphical images, or for comparing an image with a compressed version to spot artefacts. [3]

  4. Comparison - Wikipedia

    en.wikipedia.org/wiki/Comparison

    The description of similarities and differences found between the two things is also called a comparison. Comparison can take many distinct forms, varying by field: To compare is to bring two or more things together (physically or in contemplation) and to examine them systematically, identifying similarities and differences among them.

  5. Spot the difference - Wikipedia

    en.wikipedia.org/wiki/Spot_the_difference

    Solving "Spot the difference" by overlaying the left image (top left) with an inverse image (bottom left) of the right one (top right). Differences appear as non grey parts (bottom right) A way to solve a spot the difference puzzle digitally is to create a inverse version of one of the images to compare and to overlay it 50% on the other one.

  6. Comparison of digital and film photography - Wikipedia

    en.wikipedia.org/wiki/Comparison_of_digital_and...

    The pixel count of an image is related to its spatial resolution and is often used as a figure of merit. The quantity of picture elements in the image sensor is usually counted in millions and called "megapixels". [3] Sensor pixel density sets a limit on the final output resolution of images captured with that sensor. [4]

  7. Phylogenetic tree - Wikipedia

    en.wikipedia.org/wiki/Phylogenetic_tree

    The idea of a tree of life arose from ancient notions of a ladder-like progression from lower into higher forms of life (such as in the Great Chain of Being).Early representations of "branching" phylogenetic trees include a "paleontological chart" showing the geological relationships among plants and animals in the book Elementary Geology, by Edward Hitchcock (first edition: 1840).

  8. Similarity (geometry) - Wikipedia

    en.wikipedia.org/wiki/Similarity_(geometry)

    Similar figures. In Euclidean geometry, two objects are similar if they have the same shape, or if one has the same shape as the mirror image of the other.More precisely, one can be obtained from the other by uniformly scaling (enlarging or reducing), possibly with additional translation, rotation and reflection.

  9. Comparative genomics - Wikipedia

    en.wikipedia.org/wiki/Comparative_genomics

    Mummer: Mummer is a suite of tools for whole-genome alignment and comparison, widely used in comparative genomics for identifying similarities, differences, and evolutionary events among genomes at various scales. [73] An advantage of using online tools is that these websites are being developed and updated constantly.
