Machine recognition and correction of freehand geometric line sketches
Shriram Revankar, B. Yegnanarayana · 2002
The authors propose scale-independent geometric models to recognize and correct freehand geometric line sketches. These models allow flexible matching and are defined as compositions of predefined primitives that account for the freehand drawing approximations. The magnitude of tolerated approximation error depends on the geometry of the object being matched. The recognized sketches are corrected to their precise geometric shapes. A facility to correct and print the recognized objects was developed.>
