In this paper, we tackle the problem of localizing graphical symbols on complex technical document images by using an original approach to solve the subgraph isomorphism problem. In the proposed ...

Ladder logic is a programming language that mimics the logic of electrical circuits. It uses electrical control symbols to represent the input and output devices, contacts, coils, timers, counters ...

Symbols linked together form a flow chart. Flow chart programming consists of: sequences of instructions that lead to a real-life simulation decisions that result in two different actions loops ...
