can perform skin detection using set of rules (things x1 < y < x2 ) the short answer yes , can. however, luminance (y) irrelevant . it's chrominance (cbcr or uv) matters. one of cited papers in area this one (uncompressed ps file). i've implemented , seems work well. update: link above seems have become broken, here bibtex citation of paper: @article{767122, author={chai, d. , ngan, k.n.}, journal={circuits , systems video technology, ieee transactions on}, title={face segmentation using skin-color map in videophone applications }, year={1999}, month={jun}, volume={9}, number={4}, pages={551 -564}, keywords={h.261-compliant coder;chrominance component;complex background scene;face-segmentation algorithm;fast algorithm;foreground/background coding;head-and-shoulders view;human skin color;input image;luminance;perceptual quality;pixels;regularization processes;reliable algorithm;simulation results;spatial distribution characteristics;test im...

is there way how enable scroll bars in disabled tmemo component ? want let users scroll content if control's enabled property set false. know possible workaround readonly , color changes in disabled state, me lot. thanks in advance :) a control can disabled or enabled, not half dis- , half enabled. (and, nit-pickers amongst us, think no hack should make :-), reason given below). using readonly easiest solution. mindful though color changes not make control disabled. confusing user regard recognizing enabled/disabled controls. better make scrollable multi-line label. done setting (background) color equal color of parent. haven't used solution suggested , linked @hallodu, looks alternative.

i have string have parse different keywords. example, have string: "i come , meet @ 123woods" and keywords '123woods' 'woods' i should report whenever have match , where. multiple occurrences should accounted for. however, one, should match on 123woods, not on woods. eliminates using string.contains() method. also, should able have list/set of keywords , check @ same time occurrence. in example, if have '123woods' , 'come', should 2 occurrences. method execution should fast on large texts. my idea use stringtokenizer unsure if perform well. suggestions? the example below based on comments. uses list of keywords, searched in given string using word boundaries. uses stringutils apache commons lang build regular expression , print matched groups. string text = "i come , meet @ woods 123woods , woods"; list<string> tokens = new arraylist<string>(); tokens.add("123woods"); tokens.add("wo...

i'm suppose use command-line arguments take user input , use enhanced loop sum. this error: exception in thread "main" java.lang.error: unresolved compilation problem: type mismatch: cannot convert double int public class enhanceforloop { public static void main(string[] args) { // todo auto-generated method stub if(args.length !=5) system.out.println(" please enter no more 4 numbers"); else { double sum; double arraylength = double.parsedouble(args[0]); double [] myarray = new double [ arraylength ]; double value = double.parsedouble((args[1])); double counter = double.parsedouble((args[2])); for(double num: myarray) sum += num; system.out.printf("the sum %f ", sum); } } } here how far: public class enhanceforloop { public static void main(string[] args) { // todo auto-generated method stub if(args.length !=5) system.out.println(" plea...

first big marc gravell author of protobuf-net http://code.google.com/p/protobuf-net/ . it's great resource. anyhow hoping marc or else can me resolve exception. i trying implement protobuf-net on mobile devices (ios , android) using unity3d game engine. unity 3.2 uses mono 2.6, modified version of mono. it works fine in editor, on ios device @ runtime fails @ first member tries serialize. note --aot-only flag in exception. think unity builds arm assembly through mono's aot feature though don't understand it's doing under hood. executionengineexception: attempting jit compile method 'protobuf.property.property`2<gamemanagersavestate , bool>:.ctor ()' while running --aot-only. @ protobuf.property.propertyboolean`1[gamemanagersavestate]..ctor () [0x00000] in <filename unknown>:0 @ protobuf.property.propertyfactory.createproperty[gamemanagersavestate] (system.type type, protobuf.dataformat& format, memberserializationoptions options) [0...

i'm working on outlook 2007 add-in. found code loop through folders have not been able figure out how loop inside given folder examine mailitem objects (ultimately, want save emails elsewhere , modify .subject property). here have far: private void btnfolderwalk_click(object sender, eventargs e) { // retrieve name of top-level folder (inbox) , // purposes of demonstration. outlook.folder inbox = application.session.getdefaultfolder(outlook.oldefaultfolders.olfolderinbox) outlook.folder; // cast mapi folder returned outlook folder // retrieve reference top-level folder. if (inbox != null) { outlook.folder parent = inbox.parent outlook.folder; // mailbox if (parent != null) { recursethroughfolders(parent, 0); } } } private void recursethroughfolders(outlook.folder therootfolder, int depth) { if (therootfolder.def...

backbone.js relies on restful applications initialize models, progressive enhancement? data in dom (or of it), should models still make calls the restful interface though html elements exist? there library design might better suited case? you should not use dom element initialize model backend data. have nice infrastructure backbone not this. when rely on dom need change javascript whenever dom structure change due design exemple. also not rely on backbone view create model. must go other way around, model dictate views on page. just add script element , create js objects directly in there. can initialize collections, single models, etc. you can same templates or dom ui building blocks: <script type="text/js-template"> <!-- template realy elements or using js templating engine _.template--> </script> load page , have app play locally.

i came upon code while studying settimeout. settimeout executes alert 5 seconds after button clicked. <input type="button" name="clickme" value="click me , wait!" onclick="settimeout('alert(\'surprise!\')', 1000)"> however, saw alert string inside has format ive never seen before. \ occurs before ' surprise! \'. use? this indented command: alert('surprise!') . contains 2 quotes. in case command passed as string settimeout . string delimited quotes: 'string' . 'alert('surprise!')' , invalid syntax, because it's parsed this: 'alert(' // string surprise! // nonsense ')' // string so quotes inside string escaped signify "this not end of string". this worst possible way though. better way alternate 2 available quote types: 'alert("surprise!")' this mess in case though because confuse html parse...

is there way copy libraries computer has them 1 doesn't without using automated installer ? for admin part no idea, automated installer part, guess if copy dlls in same folder app exe work fine. not sure way approved ms though. you'll find dlls in c:\windows\system32 folders (for vs2008 i guess msvcr90.dll , msvcp90.dll enough). be careful, if on x64 machine x64 dlls, 32 bits 1 in syswow64). you not allowed distribute debug dlls (the 1 ending 'd' before extension).

i'm looking @ eventqueue class on oracle website: http://download.oracle.com/javase/1.4.2/docs/api/java/awt/eventqueue.html i'm not sure when should use it? should use if class has listeners 2 or more events? normally don't have submit events eventqueue, happens "automatically" when user actions (like mouse clicks , such), or when system thinks window needs repainted. the 2 methods i'm using regularly eventqueue.invokelater , eventqueue.invokeandwait() (less often). use 1 of them if doing action outside of edt (event dispatch thread) , want changes gui (like adding or removing component to/from container), such actions should occur on edt.

both crc , hash methods can used verify integrity of original data. why systems uses hash method nowadays? crc designed prevent transmission errors, not malicious action. therefore, isn't collision resistant. in particular, linear properties of crc codes allow attacker modify message in such way leave check value unchanged

i have xml document importing php dom , validating xsd (relaxng not option). want turn dom simplexml processing. function simplexml_import_dom seems thing use, documentation says "this function takes node of dom document , makes simplexml node." implies 1 node converted, not full dom tree. correct? i xml simplexml re-reading file, wasteful. if simplexml_import_dom not full dom tree, how convert dom simplexml? i've looked example code recursive dom traversal have not found examples. suggestions? simplexml objects/elements/nodes include children. simplexml_import_dom function handles recursion you.

been struggling 1 have following dom structure: <ol id="add_images"> <li> <input type="file" /><input type="button" name="removebutton" /> </li> <li> <input type="file" /><input type="button" name="removebutton" /> </li> <li> <input type="file" /><input type="button" name="removebutton" /> </li> basically i'm trying remove children , containing parent (the li tag) when clicking remove button. i have tried every manner of parentnode , removechild combinations. below javascript, can children not parent. function addfile(addfilebutton) { var form = document.getelementbyid('add_images'); var li = form.appendchild(document.createelement("li")); //add additional input fields should user want upload additional image...

since mongodb not support transactions, there way guarantee transaction? i think ti's 1 of things choose forego when choose nosql solution. if transactions required, perhaps nosql not you. time go acid relational databases.

i'm trying write simple javascript snippet delays image loading number of millisecs below. <html> <head> <script type="text/javascript"> function settimer() { var timer = setinterval("showimage()",3000); } function showimage() { document.getelementbyid('showimage').style.visibility = 'visible'; } </script> </head> <body onload="settimer()" style="visibility:hidden"> <div id=showimage> <a href="home.php"><img src="gwyneth_paltrow_2.jpg"></a> </div> </body> </html> am approaching incorrectly? thanks in advance this ok approach. there bugs, namely: document.getelementbyid('showimage')style.visibility = 'hidden'; getelementbyid should getelementbyid needs dot after ('showimage') you setting visibility 'hidden' in order show it. instead, should start out hidden,...

i'd have instance variable of "struct random_data*" used in int random_r(struct random_data *buf, int32_t *result); i've tried declaring as "struct random_data* instancebuf;" "random_data* instancebuf;" but compiler doesn't of it. how should declare variable? -edit ah,, api linux, , i'm on mac(bsd) :( oh wait, linux only? http://www.gnu.org/s/libc/manual/html_node/bsd-random.html probably: struct random_data buff; int x = random_r (&buff, ...); is easiest solution. you'll have make sure that structure has been defined. and, if buffer required long lived (like seed), make sure it's defined somewhere large scope (global or class-level, example).
