Suppose I have a schematics such as the below. I want to fast simulate it: see how the current flow and put my mouse to different positions to see how things work. Since there are many different ways to do the schematics, this requires to break the problem into human-solvable parts and computer-solvable parts -- some aspects about feature-extraction here.
Is there any feature-extraction-canabled software with OCR support and shape-extraction that would turn schematics such as the below into a simulation?
For people trying to find tools to draw schematics, please, see this thread Good tools for drawing schematics.
