logical AND of images in matlab - 


  छवि = डबल (रिक्त ('ooutput.jpg')); [एम, एन] = आकार (छवि); नकाबपोश = शून्य (एम, एन); नकाबपोश (1: 100,1: 90) = 255; नकाबपोश (175: 300,1: 90) = 255; imshow (नकाबपोश); नया = यूआईटी 8 (मुखौटा और छवि); imshow (नया);

मैंने तार्किक प्रयोग किया और छवि के एक हिस्से को प्राप्त करने के लिए। यहां एक मुखौटा बनाया गया है और तार्किक रूप से और छवि के साथ। मैं भाग लेने में सक्षम नहीं हूं। एक पूर्ण काले पिक्सेल प्राप्त करें। क्या कोई बता सकता है कि उपरोक्त कोड में गलती क्या है?

'नकाबपोश और छवि' या तो 1 है या 0. यूआईटी 8 का उपयोग करना, दोनों काले रंग के करीब है। इसके अलावा, आपकी कोड सभी छवि प्रकारों के लिए विफल हो जाती है, जो कि ग्रेस्केल यूआईटी 8 को छोड़कर।

मुखौटा समस्या को ठीक करने के लिए, इसका प्रयोग करें: 

  image = imread ('ooutput.jpg') ; नकाबपोश = false (एम, एन); नकाबपोश (1: 100,1: 90) सच =; नकाबपोश (175: 300,1: 90) सच =; छवि (~ नकाबपोषित) = 0 इम्शो (छवि);

scala - Play Framework - how to bind form to a session field -

Is there any way, I can get some parameters from the header, cookies (log in userId in my case) , And then apply it in a form which I know who will deposit the ticket? SupportForm supportForm: form [supportTicket] = form (mapping ("question" -> text, "priority" -> text) (apply support ticket. (HelpText.update) What are the good practices here? What is the call to apply the request, when I can use it (and also a good practice?) Edit An issue, absolutely deceiving anyone if I were to create a hidden area with this value. It could Ript, but the issue may be re-used in any way to verify and return the form, it can not be sure how it ....

c++ - Why does Visual Studio Release build break on non-executing code line -

When I created my C ++ program with the default release configuration in Visual Studio 10, I put a breakpoint on one line Who should never be reached. What confunded me was that when the program is running then it stopped at the breaking point. Adding a volatile statement and transferring this line to the break point does not break the execution of the code where the brake appears (though does not produce the same behavior as creating a minimum project with this function). Why is the "Release Debugger" (?) Step on this line and when executing breakpoints are executed? If I keep going after the break then false statement continues to return code execution. bool bounding box :: Cutting (int32_t xpos, int32_t ypos, int32_t dx, int32_t dy) const {int32_t intersectionX; Int32_t intersections; If ((dx> 0 & amp; amp; and & amp; xpos> rights) || (dx gt; Top) || (D & LT; 0 & amp; AOPO & Lt; BOT)) Return; If (DX! = 0) {intersection Y = ypos + (left...

Firefox reacting to JQuery setTimeout that doesn't apply -

& lt; - Only note the first image. I think some jquery is not working in Firefox, where there seems to be a problem ... but there is IE (I know, I know) var hover = $ ('# par1'), box = $ ('.sq1'); Hover.hover (function () {box.toggleClass ('index2');}); and var linkloc = $ ('# par1'), link = $ ('# frnt1'); Linkloc.on ('mouseenter', function () {function linkadd () {link.html ("& lt; a target = _blank href = http: //www.google.co.uk> & lt; img src = small1 .JPG / & gt; & lt; / a & gt; ");} Set Timeout (linkAD, 1500)}); Linkloc.on ('mouseleave', function () {link.html ("& lt; img src = small1.JPG />");}); I appreciate that the code can be a bit messy, but I'm still learning as I go. The problem now is that the top slice of the code is reacting down to the setout. (It revolves around time with setTimeout repeatedly) even though the name of the function is c...
