Method and circuit for detecting image structures in the form of lines linked topologically with one another.

摘要

P Two multiplexers connected by their inputs to the output of a counter (Z), and a comparator (C) have inputs for the reference numbers (KN1, KN2) on the other hand sent to the outputs of two registers ( R1, R2) whose data inputs are connected to an output of a third register (R3) also coupled to the address input of two memories (RAM1, RAM2) and whose input is connected to the output of the multiplexer (M1). A data input and output (D) of the first memory (RAM1) is coupled to another input of the multiplexer (M1), to the data output of the multiplexer (M2), to the input of a zero indicator ( N) and to a data entry (D) of the memory (RAM2). From a process flow control (ST), there are links to the control inputs of the multiplexers (M1, M2), to the validation inputs (EN) of the multiplexer (M2) and of the memory (RAM1) and to the write inputs (W) of memories (RAM1, RAM2). /P
