optimization - Registration of 3D surface mesh to 3D image volume -

-

i have accurate mesh surface model of implant i'd optimally rigidly align computed tomography scan (scalar volume) contains exact same object. i've tried detecting edges in image volume canny filter , doing iterative closest point alignment between edges , vertices of mesh, it's not working. tried voxelizing mesh, , using image volume alignment methods (mattes mutual) yields inconsistent results.

any other suggestions?

thank you.

generally, mesh , volume 2 different data structures. have either convert mesh volume or convert volume mesh.

i recommend doing segmentation of volume data first, segment out issues want register. canny filter might not enough segment border clearly. recommend level-set method , active contour model. these 2 used in medical image processing. these 2 topics, recommend professor chunming li's work.

and after segmentation of volume data, might able reconstruct mesh model of volume marching cubes. vertexes of 2 mesh registered through simple icp algorithm.

however, workaround instead of real registration, takes time segmentation.

i registred handler simple qtextobjectinterface , draws 10x10 red rectangle. when used qtextedit in normal qwidget app, worked. when used qquicktextedit (textedit qml component) in qt quick app, doesn't worked (nothing drawed, rectangle in textedit reserved, because when change cursor position, notice there something, empty space, nothing drawed. qtextobjectinterface intrinsicsize method called (that explains why see there empty space 10x10), drawobject method isn't. i did research , found problem here: qquicktextedit.cpp qt 5.3.0 sources (line 1821) qsgnode *qquicktextedit::updatepaintnode(qsgnode *oldnode, updatepaintnodedata *updatepaintnodedata) { . . . if (textframe->firstposition() > textframe->lastposition() && textframe->frameformat().position() != qtextframeformat::inflow) { updatenodetransform(node, d->document->documentlayout()->frameboundingrect(textframe).topleft()); c...

files not readable in swift playground . how make files readable? same code runs on xcode terminal app, fails on swift playground. demo code below. import foundation println("hello, world!") var fname:string = "/users/holyfield/desktop/com.apple.iconcomposer.plist" var fm:nsfilemanager = nsfilemanager.defaultmanager() if(fm.fileexistsatpath(fname)){ println("file exists") if(fm.isreadablefileatpath(fname)){ println("file readable") var fd:nsdata? = nsdata(contentsoffile: fname) println(fd?.length) let pl = nsdictionary(contentsoffile: fname) println(pl?.count) println(pl?.allkeys) }else{ println("file not readable") } } else{ println("file not exists") } sample images: i have thank nate cook first quick response , solid answer. just case share answer post, title misleading. see nate's answer here: https://stackoverf...

jboss7.x - JBoss AS 7.3 vs 7.4 and differences -

-
i can find eap component differences, can find differences between jboss 7.3 , 7.4? trying decide between two. the differences same eap, because eap 6.3.0 ga built 7.4 , eap 6.2.0 ga built 7.3 . eap code repository forked/rebased as7 after 7.2.0 tag . and such has own lifecycle , has diverted considerably as7/wildfly (upstream) repository. in short there no such thing jboss 7.3 or 7.4 internal version. code eap releases available on ftp , can build , use without restrictions ( ftp://ftp.redhat.com/redhat/jbeap/ ). you can see component details in https://access.redhat.com/articles/112673 i hope help.
