card-io / card.io-dmz Goto Github PK

I've spent a few days trying to get this to compile in Windows. I figured I would ask if anyone has had any success compiling this for use in a Windows Desktop application?

The card.io doesn't ready Expiry Date or card name. Both would be very helpful!

Dear
I am looking to understand
vseg_probabilities_for_hstrip(IplImage *y, IplImage *cropped_gradient, IplImage *downsampled_normed, IplImage *as_float)
specially applym_befe75da(vseg_model_input)
Would you mind give me a few words to start with? I am totally lost in model_befe75da.cpp, I didn't understand how did you generate this cpp file.
Many thanks in advance
Best regards.

I'm wondering if I can use this library server side on a Linux machine.

I have tested a lot of card's, but i surprised why card.io doesn't support not embossed (flat) cards?
I would like to do training of CNN myself, but i don't have whole training set. The training one of existed net's with small learning rate is not good idea, i think.
So, can you support my begining?

Hi,
I have some question about this codes.
First in the modelc_5c241121.cpp, modelc_01266c1b.cpp, modelc_b00bf70c.cpp, sometimes sum of softmax results is not one.
That didn’t usual case I think.

And second, I think the internal network model has a 3x3@8 conv layer, 3x3 max-pool and @ 32 FC layer and last FC layer with 10 outputs.
Is this right? but if i’m right i have no clue why sum of softmax is not one in some cases.

Thank you

Hi, I want to have a go at implementing accessibility for the blind. I want to give voice instructions as per my issue suggestion.
card-io/card.io-iOS-SDK#202 (comment)

I am just starting out so maybe this is not possible, but the plan is to:

1. Find where in the code the rectangles are detected.
2. Expose the relative positioning of the largest rectangle relative to the screen to the iOS / Android specific clients.
3. In the iOS client translate the relative instructions into localised voice commands.
4. Read out the commands using an accessibility announcement.

My questions are:

1. Is there anything that will make this super hard?
2. Is the card rectangle detected if its slightly offscreen?
3. Where in the code should I start out?

I am reading the code.
I found some magic number in number_grad_sum_pattern.
I am wondering how to set this number.
Is there any reference or tips for tuning this data?

First of all thanks for the wonderful library.
In one of my app i want to use card.io's mechanism to validate the card , but i do not want scanning feature I only want manual entry feature.

And also i have my custom UI built in for getting card's number and expiry.

Can i apply your your method to validate those info along with displaying card's image on the textfiled alon with the formatter (i.e. 4111 1111 1111 111) ?

Thanks

Presumably the library has been trained to recognise standard credit card fonts...? How could I re-train it to recognise, for instance, car number plates, or printed handwriting?

I would like to know if there is any way to capitalize on the detection capabilities of card.io's code to detect government IDs ? they are fundamentally the same size of a credit card. the objective would be only to produces a cropped image of the ID so that it could be OCRized on a server-side
any information would be very helpful

thank you !

I want to build those dmz code on arm64 platform with DMZ_HAS_NEON_COMPILETIME = 1, but it failed. Can dmz support arm64 with neon or not, do you have any suggestion if i want to build it on arm64.

Hi all, new to Card.IO. Was hoping to use it for informational cards (e.g. insurance, etc...) where I don't need credit card number capture. But running into multiple build issues. Have followed the build setup instructions and installed fabric et al. I was not able to add the sub-module for DMZ because of a permissions issue so I just downloaded it and added it to the correct folder in the project manually. When I try to build with Fabric, I keep getting:

• local() encountered an error (return code 65)
• local() encountered an error (return code 69) -- after trying to run as sudo

I also saw a comment in the docs about running "fab concat" after modifying the files -- and tried that -- but the command was not found.

When I try to build via Xcode it fails with:

• Unknown type 'namespace' in Macros.h
• "complex" file not found on the Eigen "Core"

Have searched issues for Card.IO, DMZ and Eigen and can't seem to find any solution. Wonder if I'm somehow missing some additional build settings on the DMZ/Eigen files. Maybe got borked because I added them manually?

I have confirmed that my xcbuild path is correct.

Would appreciate any suggestions on how to get this building. I'm pretty much out of ideas at this point.

thanks in advance,
tim

I read the source code about card number process, there are Number Pattern Visa like - 16 numbers, Number Pattern Amex like - 15 numbers. But there is none Number Pattern Diners - 14 numbers, So does card.io support diners card with 14 numbers? if does, how?

download dmz add card.io-iOS-source-master project
error error error!!!

you can try it

I think to replace the OpenCV in engineering with complete OpenCV, could you tell me how to go to need to modify it, or how the opencv2.framework into the card.io. How to build your own platform-specific OpenCV static libraries ?

I compile the code in widows 7,but it can't work. please help me the log is below:

Hello, Dave!
We are trying to scan an embossed card produced by a Russian payment system "МИР", and it is not recognized by the plugin. The card is always highlighted with a green rectangle, but no data is returned.

Is there any chance you're going to support the "МИР" payment system in the near future?
FYI: the most used "МИР" cards have 16 digits, they are identified by the first three digits (220) and only by them,

If we were to implement "МИР" recognition by ourselves, where should we start? We have found the 'dmz_olm.cpp' file, which contains the settings for the other cards. Are we on the right track?

In dmz_olm.cpp file, the max number of card is 16. Is there a method to recognise more digits in the card, such as 19.

Hi, i need scan cards like:

This cards:

• No Luhn
• Always 16 digits

I can not find how to create and add a new definition for Card.io can detect.

someone has done?

regards

Hello Team,

With reference to the question #8 need one confirmation.
I want to create my own screen to fill card information manually and for card validation and formatting I need to copy few files in my project from card-io like dmz-olm.h, CardIONumbersTextFieldDelegate.m, and helper folder. After taking licence do we have to copy complete repo in our project or we can take selective files from project as per our need.

dmz folder didn't download

I'm wondering what a basic Python bindings would look like. It looks like there was already thought put into this, but any direction would be very appreciated.

Can Card.io detect immersed digits (not flat printing)?

refer the below link for example

Hey guys, I'm trying to understand how your edge detection code works for detecting the card and whenever I add a break point in dmz_detect_edges in dmz.cpp and start the sample app it never breaks on it. I put a breakpoint on line 123 of CardIOViewFrame.mm, which is the line which calls dmz_detect_edges and it breaks there. It just doesn't seem to break in any of the dmz c++ code. I checked that the optimization level was none for the configuration and not sure what else would cause this. Do you have any ideas what's going on? Would help me out a lot if I could step through your code. Any help would be appreciated and thanks for providing the source code, it's been extremely helpful for me!

Our iOS application already uses OpenCV 3.0 and including card.io causes symbol conflicts since the latter uses OpenCV 2. It would be great if card.io can start using OpenCV 3.0. Are there plans to upgrade the usage to latest OpenCV 3.0 version?

Hello,
I'm trying to understand how the dmz_focus_score_for_image function works. I read through the source and it seems that it uses the llcv_sobel3_dx_dy_c_neon function to convolve the kernel:
1, 0, -1
0, 0, 0
-1, 0, 1
with the image, then it returns the standard deviation of the output from the convolution. On iOS it seems that if the returned value is greater than 6 the focus is ok and processing continues, but if it's less than 3 it sucks and triggers an autofocus. Is this accurate? And if possible could you please explain why this works or point me in the direction of some books/articles that can explain?

I tried to build devinus cython wrapper but after building i get the following error while running:

Kindly tell me what im doing wrong.

Please check line 573 of file card.io-dmz/cv/sobel.cpp. I think it should be:
uint16_t row2_index = (row_index == (uint16_t)(src_size.height - 1)) ? src_size.height - 1 : row_index + 1;
instead of:
uint16_t row2_index = row_index == (uint16_t)(src_size.height - 1 ? src_size.height - 1 : row_index + 1);

The conv models, how are they generated?
