We believe that this automaton coding approach will be useful in developing efficient image and data compression algorithms. Finally, the generalization of this approach to gray-level images, color images, and volume data is discussed. Examples are also presented to illustrate the relationship between the FSA complexity and the coded images. We demonstrate how simple image operations can be efficiently implemented directly with FSA. The display of the coded image is simply obtained by stepping through the automaton. Binary image (O= black, 1 = white) coding using a FSA follows these two steps: (1) automaton construction based on the image quadtree, (2) automaton minimization. The FSA are shown to be an interesting alternative to the corresponding quadtrees. We draw a parallel between quadtrees and rational languages that are recognizable by finite state automata (FSA), also known as automata. The language accepted and the language generated by an FSA are exactly the same.Image coding using quadtrees is useful in many applications and is well known in computer vision and graphics. Konkatenasi Finite State Automata Pada dua mesin Finite State Automata, misalkan M1 dan M2 dapat dilakukan konkatenasi yang menghasilkan mesin M4 dengan cara : 1. The language generated by an FSA is the set of all strings it can generate when used in generation mode. 53 Gambar Mesin M2 Adapun hasil penggabungan dari Mesin M1 dan M2 dapat dilihat pada gambar di bawah ini. The language accepted (or recognized) by an FSA is the set of all strings it recognizes when used in recognition mode. This is something which is true for all finite state automata and we can make it more precise: So, when used in recognition mode, this machine recognizes exactly the same words that it generates when used in generation mode. The reason is that with this input, it won't be able to read the whole input (there is no transition that allows reading an o). The problem is that it will end up in a non-final state without anything left to read that could take it into the final state. However, it doesn't accept the word haha - although it will be able to read the whole input (state 1, state 2, state 3, state 2, state 3). Mesin yang bisa mengenalinya adalah Finite Automata. Bahasa yang paling sederhana adalah bahasa reguler (tipe 3). Similarly, it accepts hahaha! and hahahaha! and so on. Definisi Finite State Automata (FSA) Pengertian Finite State Automata (FSA) Finite State Automata (FSA) adalah mesin abstrak berupa sistem model matematika dengan masukan dan keluaran diskrit yang dapat mengenali bahasa paling sederhana (bahasa reguler) dan dapat diimplementasikan secara nyata. It also accepts the word haha! by making the following sequence of transitions: state 1, state 2, state 3, state 2, state 3, state 4. At that point it has read all of the input and is in a final state. For example, it accepts the word ha! by going from state 1 via state 2 and state 3 to state 4. It can reach a final state, but there are still unread symbols left over when it does That means an FSA fails to recognize a string if: But let's have a closer look at what it means for a finite state automaton to recognize a string of symbols.Īn FSA recognizes (or accepts) a string of symbols (or word) if starting in an intial state, it can read in the symbols one after the other while making transitions from one state to another such that the transition reading in the last symbol takes the machine into a final state. The general term for such machines is finite state automaton ( FSA ) or finite state machine ( FSM ). Just that we are using them to output symbols in one case and to read symbols in the other case. That is only a small difference: Finite state generators and finite state recognizers are exactly the same kind of machine. A finite state recognizer in turn is a simple computing machine that reads (or at least tries to read) a sequence of symbols from an input tape. You will often find the notion of an output tape the symbols are written on. In the previous section, we have learned that finite state generators are simple computing machines that output a sequence of symbols.
