    en.wikipedia.org/wiki/ImageJ

    ImageJ is a Java-based image processing program developed at the National Institutes of Health and the Laboratory for Optical and Computational Instrumentation (LOCI, University of Wisconsin). [ 2 ] [ 3 ] Its first version, ImageJ 1.x, is developed in the public domain , while ImageJ2 and the related projects SciJava , ImgLib2 , and SCIFIO are ...

  3. Feret diameter - Wikipedia

    en.wikipedia.org/wiki/Feret_diameter

    The Feret diameter or Feret's diameter is a measure of an object's size along a specified direction. In general, it can be defined as the distance between the two parallel planes restricting the object perpendicular to that direction. It is therefore also called the caliper diameter, referring to the measurement of the object size with a caliper.

  4. Image resolution - Wikipedia

    en.wikipedia.org/wiki/Image_resolution

    Temporal resolution (TR) is the precision of a measurement with respect to time. Movie cameras and high-speed cameras can resolve events at different points in time. The time resolution used for movies is usually 24 to 48 frames per second (frames/s), whereas high-speed cameras may resolve 50 to 300 frames/s, or even more.

    Glass chart. A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.

  6. Shape factor (image analysis and microscopy) - Wikipedia

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

    Shape factors are dimensionless quantities used in image analysis and microscopy that numerically describe the shape of a particle, independent of its size. Shape factors are calculated from measured dimensions , such as diameter , chord lengths, area , perimeter , centroid , moments , etc.

  9. Otsu's method - Wikipedia

    en.wikipedia.org/wiki/Otsu's_method

    Like all other global thresholding methods, Otsu's method performs badly in case of heavy noise, small objects size, inhomogeneous lighting and larger intra-class than inter-class variance. [7] In those cases, local adaptations of the Otsu method have been developed.
