iphone Data Matrix BarCode - objective-c

Anyone can give any idea or suggestion regarding Data matrix barcode reader?
I used the Zbar but it supports the QR but not supporting the DataMatrix.Can u please suggest with any other source code available for free to read Data Matrix barcode reader. ##
Is there a framework or other sample code for doing Data matrix barcode recognition on iPhone / iPad?

This is a working sample but other than real time detection,it requires to take a snapshot of the barcode and sometimes it is unable to decode.

How to automate a waveform which comes from a healthcare device?

I am working as automation test engineer in healthcare. We have requirement for automating a waveform received from ECG which will be displayed in a web application.
So is there any tool to automate the waveform ?
WaveForm Sample IMAGE
Tough item to test, theoretically if the waveform isn't 'flattened' (i.e. just a picture) you should be able to pull out individual points. Image recognition is another option as the two images should match. It depends a lot on what you have to work with for data, if it's just a picture of a waveform you are pretty limited to just image based testing.
Use Sikuli.
You have to be creative with it. As long as your application is running on any JVM supported platform and there is a feature to hold the waveform in a specific interval. Then , you can do image based assertion using Sikuli.

Increase resolution of kinect rgb camera on ros

i am doing a project using deep learning and for this i need to take pictures from the kinect and evaluate them. My problem is the resolution of the pictures are 640x860. Due to this i wanted to know if ros freekinect or some library can increase the resolution given a yaml file or something like that? Thank you guys and sorry for the english
Im currently working on a project with Kinect one sensor and the camera resolution is 1920x1080.
if i am not wrong you are currently using the old xbox 360 kinect from what i see here.
I have not heard of libraries that can increase resolutiono yet(this does not mean it do not exist)
But my suggestion is to use the latest hardware found in Microsoft Store here. It cost about $150.
Cheers!

How to use Vision toolkit in labVIEW?

We have a 16-bit image and trying to process that image using Vision module LabVIEW 2010. Is 16-bit image possible to process in Vision toolkit ?
We are buying Biomedical Toolkit for LabVIEW 2014, We are not aware of processing 16-bit images in that toolkit.
When I am opening and saving the 16-bit tiff image, intensity values of image are varied 10 times of original image intensity ( example: from 3,200 to 35,000). Why it is happening. I have attached screen shots of small code and inverse help context.
I'll address only one of your questions:
yes, NI Vision Development Module can process 16-bit images.
I'll suggest to give a look here, too:

raw frames windows phone 8.1

I need to get raw frames from the Camera in YUV/YCbCr format on windows phone 8.1 (without Silverlight), I don't see any example on internet, is it possible using MediaCapture or CameraPreviewImageSource (Nokia SDK) ?
Thanks
The recommended way to process raw video frames on Windows Phone 8.1 is to write a custom MFT plug-in and then add it to the MediaCapture object via AddEffectAsync. The MFT acts as a DSP filter between the decoder and the XAML rich compositor.
You can choose the color space that you want to support in your MFT and Media Foundation will automatically insert color space converters for you. Keep in mind that the color spaces available on the Phone are limited. That said, NV12 is the standard color space for most video devices and is considered a 4:2:0 YUV color space.
While this sounds simple in theory it can be quite complex in practice. MFTs must be writing in C++ / MoCom. Writing an MFT does require rather deep knowledge of C++ and COM. I don't want to scare you away from giving it a try but it does have a learning curve.
Here is a sample for Windows Store that shows you how to create a MFT plug-in and add it to the MediaCapture object. Unfortunately for whatever reason this sample did not get converted to a Universal app. However, it should be easy to do the conversion. Since this is such a seminal sample I will request that we publish it as a universal app.

I hope this helps,

Inputting analogue data via USB

I am trying to build this device which takes analogue input from the earth , converts them into electrical impulses which I wish to input into a android smartphone for data analysis. I initially thought about using the 3.5mm jack of the android device. Apparently Android does not support input through the 3.5mm jack. So I decided to use the USB cord as the input.
Now my question is will my android phone or tablet directly able to read the USB data, or has it to be fed through some microcontroller??
I'm not sure I'm understanding your question correctly, are trying to measure soil conductivity and find out if your plants need water? which is easy. Or are you trying to build a heart monitor? which is a bit more complex.
Anyway if you are interested in conductivity measurement with Android, you may want to have a look at this device, it is driver free and works on Android.

I believe V-Alarm is using them as well
