node.js - Information needed for 3D reconstruction from x-ray images using OpenCV -

-

anyone know starting point check out, 3d reconstruction x-ray images/2d images using opencv. im trying project using nodejs , js version of opencv. trying recreate bone structure 2d x-ray image(multiple views available). open source codes(in python/c/c++)/algorithms/guides/anything appreciated.

thank you

typically have following:

  • n image layers each image dimension = width * height
  • interpretation color value "thickness value"

the general idea is: create 3d map of dimension n * width * height either floating point or byte values. add image layers map, giving huge 3d texture. can define tissue-thickness interested in, example bones. search each cell in 3d map values differ "less bone-thickness" "bigger or equal bone-thickness" (or cells have exact thickness value stored) , mark cells "bones". have voxel grid of bones :)

a better approach use marching cubes , interpolate between thickness changes.

probably, if google "marching cubes" , "x-ray" you'll find more detailed information (and university lecture notes) different ways solve approach. example: http://www.eecs.berkeley.edu/~jrs/meshpapers/lorensencline.pdf , papers might find more tags search for.

i created own android project , cut , pasted code exercise: http://androidexample.com/show_phone_contacts_in_autocomplete_suggestions_-_android_example%20/index.php?view=article_discription&aid=106&aaid=128# when build project no errors or warnings. when run project window error: annoyingly, can't make window smaller, can't click of buttons. cick 'x' @ top, close it. here's project structure: where getting 'autocompletemain' from? (note small c) class named autocompletemain. help. and have activity included in android manifest, in case you're wondering: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.androidexample.autocompleteedittext" android:versioncode="1" android:versionname="1.0" > <uses-permission android:name="android.permission.read_phone_state...

i trying decrypt data using certificate private key. works fine when certificate installed on local machine (i using self signed certificate testing , have private key certificate) when try access private key remote machine using same code, "keyset not exist" exception. i using console application testing, , have made sure id have read permissions on private key on remote server. here sample code using: var store = new x509store(@"\\server1\my", storelocation.localmachine); store.open(openflags.readonly); var result = store.certificates.find(x509findtype.findbysubjectname, "server1.test.com", false); var certificate = result[0]; store.close(); //this succeeds both local , remote server var rsapublic = (rsacryptoserviceprovider)certificate.publickey.key; //this succeeds local, fails remote server var rsaprivate = (rsacryptoserviceprovider)certificate.privatekey; here exception call stack unhandled exception: system.security.cryptography.crypto...
