2. 3D reconstruction from multiple images - Wikipedia

   en.wikipedia.org/wiki/3D_Reconstruction_from...

   The essence of an image is a projection from a 3D scene onto a 2D plane, during which process the depth is lost. The 3D point corresponding to a specific image point is constrained to be on the line of sight. From a single image, it is impossible to determine which point on this line corresponds to the image point.

3. Image conversion - Wikipedia

   en.wikipedia.org/wiki/Image_conversion

   Many image formats are native to one specific graphics application and are not offered as an export option in other software, due to proprietary considerations. An example of this is Adobe Photoshop 's native PSD-format (Prevention of Significant Deterioration), which cannot be opened in less sophisticated programs for image viewing or editing ...

4. ImageJ - Wikipedia

   en.wikipedia.org/wiki/ImageJ

   ImageJ supports image stacks, a series of images that share a single window, and it is multithreaded, so time-consuming operations can be performed in parallel on multi-CPU hardware. ImageJ can calculate area and pixel value statistics of user-defined selections and intensity-thresholded objects. It can measure distances and angles.

6. Autocollimator - Wikipedia

   en.wikipedia.org/wiki/Autocollimator

   An autocollimator is an optical instrument for non-contact measurement of angles. They are typically used to align components and measure deflections in optical or mechanical systems. An autocollimator works by projecting an image onto a target mirror and measuring the deflection of the returned image against a scale, either visually or by ...

7. Structural similarity index measure - Wikipedia

   en.wikipedia.org/wiki/Structural_similarity...

   The SSIM index is a full reference metric; in other words, the measurement or prediction of image quality is based on an initial uncompressed or distortion-free image as reference. SSIM is a perception -based model that considers image degradation as perceived change in structural information, while also incorporating important perceptual ...
