macOS Image matching software for Cigars.

I don't really have any specific knowledge on this subject, but from my general understanding of the state of technology, the type of thing you're looking to do is VERY difficult. I would think implementing some sort of numbering/inventory system with tags of some kind would be the way to go. You could have a human browse through an image database to double-check, but using software to compare images is still really hard to do.

A photo is really just a grid of color boxes to a computer, and 2 different photos of the same object (especially with different angles, lighting, distances, backgrounds etc.) will look completely different to a computer. Like I said though, I'm not really an expert at this kind of thing, so perhaps someone else might know of a better solution. Best of luck to you.

The app SnapTell has this form of recognition so to speak. It identifies music cd, and games and dvds. They have other companies using their engine to do specific searches but I don't know what it takes to use them or how much $$. Check out their website, just search for snaptell

Knowing nothing of cigars, i would suggest another system than trying image recognition. Especially if sometimes a mere size difference means a different "product" as far as your system is concerned.

I don't know if plastic "sleeves" over cigars would taint them, but that would be a place a label could go (people swapping sleeves is the same sort of problem every store has with people retagging, so you'd need some means of preventing that... sealing the wrappers, etc.). If this wouldn't work, then perhaps some sort of "access control" system to the individual cigars? Say, the customer is given a tag to scan, card to swipe, etc. and when they want a particular cigar they swipe the card, scan an rfid tag, etc. near the case, indicate a quantity by some means, and the case will open/dispense the proper number of cigars. While they are in the store, the system would track the type and quantity of cigars they've swiped for. Then the person at the desk would swipe their card/tag/etc. at the register, and visually inspect that, in general, the quantity and type is what they'd swiped for. This obviously requires more specialized hardware, but it was the first thing that sprung to mind. It might be easier to purchase premade vending machines that don't "drop" the items which accept credit cards and allow purchases to be made from there?

Again, this is well outside my areas of expertise, but i thought i'd put the suggestions out there.

The SnapTell stuff looks really impressive. Thanks for the reference.

EDIT: I thought about the sleeves you mentioned Lee, but I think humidity with cigars is a big deal and I'm not sure how sleeves would affect that (although perhaps you could use breathable sleeves made out of something other than plastic).

I would guess "aficionados" would want the label intact, or at least be able to remove anything that's placed over the label... but in any event, with an inventory of 300, you would just need 10 bits of data to get you more than 3x the number of products your expecting... Maybe make it 16 so you have plenty of room to cycle through product generations, years, etc. More if you think it's necessary.

I'm guessing you could get the data you need into a pretty tiny label. It seems like aztec is public domain, and "dense":

There is an online encoder here:

This is the encoding of:
"2009 EL REY DOUBLE CORONA COLORADO"
You could just use a number instead, or item code, etc., but this was the result:


I'm not sure what sort of scanners would be needed to scan something so small, but the data can definitely be encoded and printed very small.

Good luck!

Edit: After a bit more readying DataMatrix seems to be more common, and is also unencumbered.

What if you made a second label for the cigars that you would slide on with your bar-code/inventory number stuff on it? When the customer purchases the cigar, the employee would slide it off and scan it, and the customer would receive the product without any sticker residues on the factory label. Just an idea.

The curent state of the art is not as good as you'd like. Right now you'd have to find an application that can tolerate mistakes. The outdoor add example given above is a perfect use of a technolog that is 90 or 99 percent accurate. I think a store clerk could do better.

Even if the technology itself were very good, do you know what a consultant would have to charge yo to integrate the pattern recognition engine into your point of sale system? This is NOT the same kind of work as where you can find some kid to build you a web site. Software engineers at this level make reasonable middle class pay and I doubt it could be done is less then 1,000 hours. Cheaper to simply hire more skilled sales help.

But it's kind of moot because I assume you would require very high level of accuracy.

Hi

I think it would be straight forward to measure the length and diameter of the cigar in software, and also to identify the label. I'm not so sure about colour because being a none smoker I imagine all cigars as the same brown. Now the question is, given the length, diameter and label of a particular cigar, would this information be enough to identify it completely? You need to bear in mind how consistent the length and diameter are for a particular cigar type.

I thought I'd chime in as I do image processing for a living.

The 1000 hours estimate quoted above seems a little out of line to me, and I also think that if you are technically savvy, you don't really need the expensive consultants. However, I don't think your simple "webcam" solution would be sufficient. (Close, but no cigar - I couldn't resist)

What you will need is a setup with good lighting and a good (black-and-white) industrial camera. Mount this stuff near the cash register on some kind of fixed contraption; since you mention that the difference is sometimes only in size, it's tough for the setup to distinguish a small cigar held closely to the camera, and a larger one held further away. You'd instruct the employee to place the cigars on the desk, label side up, under the camera.

There are software packages out there which you can "train" yourself to recognize various objects.

BUT you may be solving the wrong problem here. If you are opening a specialist cigar store, you should probably invest in an employee who knows one cigar from another.

If I walk into a store like that, I would expect the employee to be knowledgeable. If he tells me he is out of "Heeren van Ruysdael Composition 12" I don't want him to suggest some "Balmoral Overland" because they're just about the same in size.

Imaging would be the best and I sent an email to SnapTell letting them know what I was looking for. I will look into the Aztec bar code too. Perhaps I can embed this into a POS that I am working on.

Thanks for the support

Let me know what they say, I have looked at them (gave the reference), but not enough to inquire about the terms and fees.

yeah that idea would be very very very hard to pull off.

Everyone should walk around with a modified iPhone! =p

They do make an app sort of like that for pharmacists to show the different type of medications.

OP tags would not work for various Cuban 'Cabinet Selection' cigars, e.g. Punch or Partagas, as these do not have a cigar band. So where would you want to place a tag on such cigars?

obviously the solution here is smokable RFID chips that are inserted into each cigar. =)

Cognex and the Matrox Image Library are widely used. There are also companies which deliver the whole chain (acquisition hardware + image processing software). I was impressed by NeuroCheck at the last trade show I went to (Vision 2008) (http://www.neurocheck.com/). Be prepared to bring your wallet, though.

Many of these applications can quite easily be programmed to measure critical dimensions automatically (diameter, length, tapering, even OCR of the label) but it would require a bit of extra work to map these numbers to cigar types.

Cost effective system.

I am an auditor so I have done inventories in the past. The question here is controls and costs. Having a bin system with bar-codes on the bin would probably be your best bet as opposed to an unreliable image scanning deal. On top of that you have daily inventories of each bin to catch the flub ups. I am not sure if there is barcoding software for mac-osx, but I do know that a barcode system in XP for around $150 for basic functionality.

Just a slight OT question. Is there any software / code on the market that you can add to your own programs or stand alone that can analyze images and determine what it is?

I am opening a Cigar Store. Cigars all look the same for the most part besides the labels on them. I am hoping to write a 'simple' app for the Point Of Purchase that the employee can just put the cigar in front of a USB camera and then it identifies the cigar from a photo that is on file. My worries are that an unaware employee can sell a $30 cigar for $5 because they don't know better. Also some cigars have the same labels but are different sizes.

You can't really bar code cigars so I thought an image base system that can match it to ones that are on file and give you the price?
