This review paper offers a contemporary literature survey on symbol spotting in architectural drawing images. Research on isolated symbol recognition is quite mature; the same cannot be said for...doi:10.1186/s41074-019-0055-1Alireza Rezvanifar...
Digital architectural drawings constitute a very challenging dataset for testing symbol spotting methods. This application was also noticed as being of particular interest in DIA communities, as can be seen in the Graphics Recognition workshops and related conferences. For example, [5–8] report on t...
We propose to use deformable template matching as a new approach to recognize characters and lineal symbols in hand-written line drawings, instead of traditional methods based on vectorization and feature extraction. Bayesian formulation of the deformable template matching allows combining fidelity to the...
