how to see the processed image without imshow?



I'm using beagleboard without GUI so I can't use cv2.imshow.
how can I see the processed image ? like send data to others computer in local network or something.





What OS are the other computers using? What OS is the BeagleBone running? Do you ssh into your BeagleBone to run your OpenCV program?

I would install XQuartz on your Mac so that you have an X11 server, then when you login to to your BeagleBone via ssh, use ssh -Y user@beaglebone and then imshow() will show up on your Mac's screen.


ssh


ssh -Y user@beaglebone


imshow()



Have a look at this answer to see how to automate that with your ssh config file.


ssh



Test that XQuartz is set up correctly on your Mac first by running xeyes or xclock from the Terminal. When that works, try sshing into your BeagleBone and running xeyes or xclock there. Once that works, try with OpenCV imshow().


xeyes


xclock


ssh


xeyes


xclock


imshow()



Alternatively, share a directory on your BeagleBone with the Mac via NFS or Samba, and save your images (from your OpenCV code) on disk in that directory on your BeagleBone. Then mount that directory from the Mac (using ⌘K in the Finder) and use Preview or QuickLook to view the files.


Preview


QuickLook



QuickLook is when you tap once briefly on a file in Finder with the mouse to select it, then press SPACEBAR to quicklook at the file and once more to close QuickLook.

PHP contact form sending but not receiving emails

PHP contact form sending but not receiving emails I have created a contact form using PHP to send the data. The form seems to send fine as there are no errors and success message appears, however I am not receving the emails into the designated inbox. I am using PHPMailer as I originally tried just using the php 'mail' command which I now understand is a bit hit and miss. I cannot see why I would not be receving the emails so I would be very grateful for any help that could be given. I'm quite new to PHP so please be patient with me :) <?php use PHPMailerPHPMailerPHPMailer; use PHPMailerPHPMailerException; $msg = ""; if (isset($_POST['submit'])) { require 'phpmailer/src/Exception.php'; require 'phpmailer/src/PHPMailer.php'; require 'phpmailer/src/SMTP.php'; function sendemail ($to, $from, $body) { $mail = new PHPMailer(true); $mail->setFrom($from); $mail->addAddress($to); $ma...

Do graphics cards have individual ID by which single devices can be distinguished?

Do graphics cards have individual ID by which single devices can be distinguished? I have several graphics cards of the same manufacturer and same model and I want to distinguish them not only by the pcie socket they reside in but by some individual value I can read from the hardware. Is there such value and if so what would it be called and how could I access it? Right now I'm using modern nvidia cards (10xx series) and nvidia inspector.but I'd prefer if there was any value that was also applicable to amd. I have programming and scripting knowledge. I am running Windows 10 1 Answer 1 This is a powershell example to pull information from video cards. The DeviceID is supposed to be unique but only if the manufacturer supports Windows Display Driver Model (WDDM). (I copied this directly from docs.microsoft.com) $strComputer = "." $colItems = get-wmiobject -class "Win32_VideoC...

Create weekly swift ios local notifications I can create daily notifications but not weekly ones using swift 3 ios 10 User Notifications framework.
