Optical magnification is the ratio between the apparent size of an object (or its size in an image) and its true size, and thus it is a dimensionless number. Optical magnification is sometimes referred to as "power" (for example "10× power"), although this can lead to confusion with optical power. For real images, such as images projected on a screen, size means a linear dim… WebbThe Harvard paper published a data set: Im2LaTeX-100K - that contains a prebuilt dataset for the image-2-latex system.
