How to render the 3 D models from CT scan DICOM files on the marker for medical augment reality purpose in Android application

I am new to android and ARToolkit.I have to develop the android application which can augment and render the 3D models from CT scan images in DICOM format on the detected marker. I am using ARToolkit SDK for my purpose. But don't how to proceed with the dicom files and render the 3D model on marker. Someone please suggest some approach. Any sort of help will be highly appreciated.
Thanks

I recommend the following process;
Figure out a tool for segmentation. This is the process whereby you will build a 3d model of subset of the data depending on density. For example, you will build a model of the ribs of a chest CT. You should do this outside of Android and then figure out how to move it later. You can use tools like ITK and VTK to learn how to do this stage.
If you want to avoid the ITK/VTK learning curve, use GDCM (grass roots dicom) to learn how to load a DICOM series. With this approach you can have a 3D array of density points in your app in a few hours. At this point you can forget about the DICOM and just work on the numbers. You still have the segmentation problem.
You can look at the NIH app ImageVis3D which has source code and see what there approach is.
Once you have a segmented dataset, conversion to a standard format is not too hard and you will be on your way.
What is the 'detected marker' you refer to? If you have a marker in the image set to aid in segmentation, you can work on detection from the 3d dataset you get back from loading the dicom data.
Once you have the processes worked out, you can then see how to apply it all to Android.

It seems a little old but, recommended for a start: Android OpenGL .OBJ file loader
I was wondering too about building a CustomView to address your needs, since in a CV you can display anything.

Creating video from stream bitmap in android

I have bitmaps i want to create video by sequence of bitmap in android.
My application receives a sequence of images (BitmapImage) from an external device with rate 10 fps.
I need to create an avi file from this images and then, save it on filesystem. How can I obtain this result? Are there any Android libraries can I use for this purpose?
Please Help

I'm a little late here, but yes there is a library for this. You can find it here: opencv for android. To integrate it with your android project, follow the instructions under Quick Start for OpenCV and FFmpeg. The best part about this library is all of the JNI wrapping is done for you. Although there is lack of documentation, there are a few links to similar projects using this library which you can find here. Hope this helps.

Is there any way to synthesis image in Android native API or using HTML5

I want to build a mobile app with the following function:
Let user choose an image, then we generate a picture base on that picture.
The generated picture has some specified text with specified font.
There is another picture, which may be a PNG file, used as foreground.
Output that generated picture to user's device.
Is there any way to synthesis image in Android API or using HTML5?
I prefered use some Javascript way to do this, so I can easily build the app cross platform, but I don't know whether JS can do that.

For this purpose you can use HTML5 canvas https://developer.mozilla.org/en/Drawing_Graphics_with_Canvas
If you want to code this using Android API you can use Canvas:

By the way there is a good guide "Displaying Bitmaps Efficiently" http://developer.android.com/training/displaying-bitmaps/index.html

loading SVG on android program

I want to change bitmap images (.png) in my android application to SVG images. I work with the android basic engine.
what is the best solution?
thank you for help :)

SVG is not a image supported by android

That means you need custom code to make it work
I haven't tried myself but a quick google search and voila
