in need of PROFESSIONAL ADVICE for thesis

[hunter34ray]

We are students from UST currently in our thesis, we are willing to pay considerable amount for anyone willing to guide us in our topic, i repeat, guide not make our thesis.  Our topic is a money counter capable of counting and sorting a stack of assorted bills displaying in its LCD the breakdown of the quantity of each bill and sorts the bills using matlab image recognition. you may message me here in case your interested and discuss a possible appointment and the details of our approved topic.. we've already defended our thesis proposal and the specifications may be explained in case you guys are interested.. thank you mam/sir.. God bless

ang alm ko si ser malditah...nagawa na yan..wala nga lang LCD....kaso nasa laguna yun....try mo i-PM

Another option is to just directly post your problems/questions here in this forum
There are numerous experts here that could help you.
Two heads are better than one. Plus its FREE.

For your problem, if you don't check for fakes on the money stack, a simple color detection could be done even without image processing. 

The more difficult part is the mechanical. Old crumpled bills are difficult to grab and separate.
But this could be remedied by just using an existing off-the-shelf money counter and use the mechanics.
With this solution, a color detector (either with photocell and color filters or CCD), an MCU and LCD is all you need.

LCD display is trivial and lots of example codes done by members in this forum.

Just ask the RIGHT questions and many are willing to answer you.

when i see a problem in my projects there is sometimes not in books nor in publications. like coin sorter, paper dispenser, or bit banging.... anyways look into google patents.

i'm more to google patents than wikipedia. it also contains the illustration, and nice documentation. they are SCANNED PDF not a copy paste document.

check out google patent.

Bill handling apparatus >>> that is what inside an ATM machine. and how it sorts in bins.

Bill-discriminating apparatus >>> patern based matching.
ginagamit for atm deposit machine.

thank you po for the advice and suggestions.. ano pong name ni sir malditah d2 sa forums? very helpful po ung mga patents.. salamat po.. tagal na kasi naming naghahanap sa net ng kahit example schematics, wala eh. .di namin alam kung pano buuin.. un pong suggestion regarding sa pagbili po. parang di po sya ganun kaganda kasi po hindi kami ganun kagaling sa pagbaklas baklas at kung masisira lang sayang naman po.. mahirap po kasi communication sa chat or ganitong forums po eh.. kaya po we are requesting for a formal meeting kasama po ung mga kagrupo ko.. para maliwanag po tlga lhat at active ung question and aswering po.. we really appreciate your advice.. marami pong salmat..

kaya mahal 'yung ibang money counter. binalak 'to dati sa pinapasukan ko to quickly count photo paper, pero 2M ang quote sa amin.

[insomartin]

kung kaya naman sa mathlab. pwede din mag OCR for the serial numbers for checking blacklisted bills or serial numbers that is not printed.
yung isa is UV ink. lahat nang currency natin may UV prints.

about sa mechanical, oo nga medyo complex.

[hunter34ray]

kaso po sir, matlab na po ung nasa paper namin.. nagdefense na po kasi sa proposal eh.. dun din po kasi kami familiar eh.. tska po sa checking for black listed serials, di po sya kasama sa scope namin.. bale wala po kaming counterfeit.. count, sort and display lang po tlga bale..

[blastronics]

Try nyo mag inquire dun sa mga supplier ng mga vending machine. dun sa vending machine mismo (coke)meron dun contact number. Or kaya abangan nyo yung nagseservice nung machine. Then ask nyo kung pwede makabili  sa kanila nung bill acceptor kahit yung medyo sira, at least may mapagaaralan kayong mga parts at kung panu yun gumagana. meron akong alam ng supplier nung bill acceptor, di ko  lang alam kung magkanu quote nila para sa bago.

Pwede ba sa real-time image processing ang Matlab?

[hunter34ray]

tingin ko po sir pwede naman ang matlab kasi po pumayag panel namin eh.. hehe.. ung sa vending machine po? di po ba sobrang bagal ng feeding nun?

How fast do you need to count the money? X bills/second?

The kind of sensor you need and the processing power depends on this.
The mechanism of the counter should also be able to cope up of this speed.

[hunter34ray]

di ko po sure eh.. pero parang 500 po ata per minute.. yet to confirm po.. any sugestion po sa motor.. ung sensor po bale camera lang po ysa.. tingin nyo po?

[rdpzycho]

kahit ordinary DC motor pwede na. 'yung flaps na kukuha ng pera ang pahirap.

That's roughly 8 bills per second!
If using matlab on a PC, your problem will be the data acquisition hardware and speed.

For example,if using a usb webcam, most likely it will do 15 frames per second. And will give you only 2 frames per bill.
I doubt matlab could process the info in-between 2 frames plus the data transfer.

You also need to transition of the bill movement (detect changes if the next bill is presented).
A detector (switch) is needed for this and is difficult to synchronize which bill is moved currently and picture taken.
This is due to the latency of data acquisition. This can be remedied if the latency is "fixed" or predictable.
This is difficult on Windows OS for it is not an RTOS (real-time OS) because the delays are not constant or interrupts are serviced unpredictably.

senxa na po sir zero mejo di ko nakuha lahat sa reply mo.. pasenxa na po.. ang design po namin eh may lalagyan ng stack of bills na iproprocess, the stack container will position the bills parallel to the floor. tapos ung camera po nakaposition sa ilalim nya.. so bago po pumasok ung bill.. nakunan na po sya.. tska sabi po ng adviser namin.. mejo mamahaling cam daw po ang gamitin.. prob po namin ung microprocessor na gagamitn po para sa pang drive ng motor at ng lcd display.. zilog po sana kasi un ang available sa uste.. tingin nyo po mga boss? tska ung flaps nga po sir pzycho..

With your speed requirement of 500 bills/min., you need either a powerful DSP chip or an embedded linux PC.
Zilog MCUs cannot cope up with the speed and it may lack memory for image processing.

Mechanical requirement as well for this speed is another big challenge.

My earlier suggestion still applies here.
An off-the-shelf money counter could be modified for this application.
And If you plan to use an ordinary MCU, such as zilog, a simple color detector only is needed.
As you stated, you don't need to check for counterfeits.

[hunter34ray]

sir zero, the mcu will not be the one to process the images.. the pc will through an exe program by matlab. so the mcu's job is really to jst to drive the motors and the lcd display.. salamat po sa suggestion sir..

[rdpzycho]

tulad nga ng sabi ni sir zerowing, mahirap sa Windows 'to dahil 'di exact ang timing. kung mabagal siguro rate pwede.
