The current version of Scan2CAD is version 6c. 24th July 2001 Fixed problem where some Group 4 TIFF files were being saved as negative images. Added PNG raster file support. Made Scan2CAD's Tiling functions more visible. Neural networks Scan2CAD recognizes text by means of technology called neural networks.
Neural networks work in an analogous way to the human brain.
They learn to recognize shapes and patterns from a range of examples. By default, Scan2CAD uses a neural network that has been trained to recognize standard fonts. It may not recognize other fonts well and may also fail to recognize standard characters that are narrower or wider than normal or that are italicized. This is because a single neural network cannot be trained to recognize a wide range of fonts accurately - ideally you need one neural network for each font type. A sample of the text that the neural network has been trained to recognise - i.e. a small raster image containing a piece of text.
