Sketch Recognition of Digital Logical Circuits

چکیده
Two tasks are prevalent in most sketch recognition systems grouping and recognition. We describe a novel grouping algorithm which clusters pen strokes into symbols. This algorithm is unique because it allows a feedback loop which can improve the performance of other phases in recognition. In our experiments, we improve the percentage of perfectly grouped symbols from 76.7% to 94.2%. Additionally, a state-of-the-art symbol classification technique was improved for use in the domain of digital logical circuits. On average, this technique improved the accuracy of symbol classification in the the “factory trained” setting from 80.8% to

Sketch Recognition for Digital Circuit Design in the Classroom
Digital circuit simulation programs are powerful in education because, unlike paper, they allow students to explore and verify the behavior of a physical system. Unfortunately, learning to navigate the interfaces to these tools can be time consuming and useless from a pedagogical perspective. Our central aim is to build a tool that allows students to sketch circuit schematics on a Tablet PC and...
متن کاملDesign and Implementation of MOSFET Circuits and CNTFET, Ternary Multiplier in the Field of Galois
Due to the high density and the low consumption power in the digital integrated circuits, mostly technology of CMOS is used. During the past times, the Metal oxide silicon field effect transistors (MOSFET) had been used for the design and implementation of the digital integrated circuits because they are compact and also they have the less consumption power and delay to the other transistors. B...

متن کاملStatic Simulation of CNTFET-based Digital Circuits
In this paper we implement a simple DC model for CNTFETs already proposed by us in order to carry out static analysis of basic digital circuits. To verify the validity of the obtained results, they are compared with those of Wong model, resulting in good agreement, but obtaining a lighter ensuring compile and shorter execution time, which are the main character...
متن کاملModeling and Simulation of Substrate Noise in Mixed-Signal Circuits Applied to a Special VCO
The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...
