how can i read image from my google drive, process it and sent the output to my email address?, image after image, automatically?

I have a matlab program, named my_program (which is located in a desktop folder) that reads an image (eg image1.jpg) from the folder (by imread (image1.jpg)), processes it and outputs (the output is specific coordinates (x,y) in the image). I want to make that:

1. Input: The program will read the images from a folder in my cloud in Google Drive, automatically. Each time that new image is uploaded to the folder, the program reads it, processes it, and outputs the output. For simplicity, the first image is: image1.jpg, the second is: image2.jpg, the third is: image3.jpg etc.

2. Output: The output (the coordinates) will be sent to a folder in my cloud in Google Drive, or, even better, the output will be sent to my email address. My email address is: [e-mail]. After that I want that the program will delete the image (that already processed) from the folder in Google Drive.

The program will wait for a new image to be uploaded to the folder, and then it will read it, process it, send the output to my email, and delete it. And so on.

Matlab can send e-mails, so the only thing you really need to do is finding a workable API for Google Drive that will work on a slightly older release like R2014b. If there is anything, it will probably be on the File Exchange, and you have good chances on it working on your release.

i succeed to send a text message to my email (string message) with the function 'sendmail', but I can not send to my email, values ​​of variables (the coordinates, which are within variables) and, I still do not know how to get the input from the folder in my drive

It looks like it might be possible to imread() an image out of google drive, once you have the file identifier.

Following the "uc" hint in https://stackoverflow.com/questions/10311092/displaying-files-e-g-images-stored-in-google-drive-on-a-website

I have a photo on drive. Normally if I ask for the shareable link for it in any of several ways, I get told it is at https://drive.google.com/open?id=0B6Z9gtnwRLLTMDVTRWptemVwemM . (Notice the lack of file extension.) But you cannot use

img = imread('https://drive.google.com/open?id=0B6Z9gtnwRLLTMDVTRWptemVwemM', 'jpg');  %fails

as it turns out to be a link to a web page.

The uc hint says to change the 'open' to 'uc'. And that appears to work:

img = imread('https://drive.google.com/uc?id=0B6Z9gtnwRLLTMDVTRWptemVwemM', 'jpg');  %works
imshow(img);

Now.. how to get the URL in the first place is a different question!

[inon hen]

thank you! it works!

Now I need to know how my program will automatically read the URL (shareable link) of a new image that upload to this folder in my 'Google Drive'?

Then you should change/mark this one as the Accepted answer instead of mine.

I can chime in with info on sending an email from MATLAB using a gmail account. I do not know how to set this up for other email clients.

Use the sendmail function in MATLAB. See this post for details, including adjusting the security settings of your gmail account. Here's some starter code:

myaddress = 'yourEmailAddress';
mypassword = 'yourPassword';

setpref('Internet','E_mail',myaddress);
setpref('Internet','SMTP_Server','smtp.gmail.com');
setpref('Internet','SMTP_Username',myaddress);
setpref('Internet','SMTP_Password',mypassword);
props = java.lang.System.getProperties;
props.setProperty('mail.smtp.auth','true');
props.setProperty('mail.smtp.socketFactory.class', ...
    'javax.net.ssl.SSLSocketFactory');
props.setProperty('mail.smtp.socketFactory.port','465');

To send an email, use the syntax sendmail(recipients,subject,message,attachments). The first 2 inputs are required. The second 2 are optional.

Thank you all.

It seems very difficult to read an image from my 'google drive' account, automatically (without copying the URL link of the image). So, I want to leave this mission.

Instead, I want my program to read images from a folder on my desktop. And when I upload a new image to the folder, the program will read the image and process it. The names of the images are: 'image1', image2 ',' image3 'and so on ...

I want the program to run continuously, until I click 'stop'.

Can anyone help me?

[Image Analyst]

Yeah, if you start a new thread on this, because monitoring a folder for new files that appear is a totally different topic than sending an email with an attachment.

[Jordan Reid]

By downloading the Google Drive desktop app, Google Drive essentially becomes a folder accessible by MatLab and any other applications operating locally on the computer.

[Walter Roberson]

Google Drive Desktop App was taken out of service several years ago. Now there is just Google Backup and Sync.

See my attached email sending demo.

[inon hen]

Thank you. But I still don't know how to get a picture from my "Google Drive" and then process it with my program. Is it possible?

[Image Analyst]

Can you access using something like imread() and the URL of your image?

[inon hen]

I tried this tipe of the 'imread' function: myImage=(URL,'image URL')

but it didn't work to me.

[Image Analyst]

That doesn't look like a valid URL. If you were to give people a link to your image, what would you give them?

[inon hen]

'image URL'- it was just to the explanation.

For example, a real image URL is: 'http://heritage.stsci.edu/2007/14/images/p0714aa.jpg'

When I tried to read the image like that (with the 'imread' function) , I wasn't succeeded.

but when i tried the function 'webread' (like the 2 lines below), It worked.

url = 'http://heritage.stsci.edu/2007/14/images/p0714aa.jpg';

rgb = webread(url);

but, i still not succeed to read a picture that located inside a folder in my 'Google Drive'.

[Mei Sing Wang]

Hi there.. I have same issue as well, may I know did you found your solution?

[inon hen]

Hello Mei Sing

My program reads thermal images from a certain folder, processes them, and finds the coordinates of the center of the hot objects. The program displays a window showing the steps of finding the object centers. In addition, the program displays the coordinates of the object centers on the Matlab display and sends the coordinates to the recipients we determine by email

the recipients can be changed in "steps_function" in line 9.

"short_main" is the main script. "short_main" call to "steps_function" and "steps_function" call to "canny_detection".

Note that "short_main" (line 13) reads files from a folder that is in a specific location, so if you run the program from another computer you should check that the path of the folder from which the images are extracted is the correct path.

The images are called in the order of their name, starting from image1.jpg and then moving to image2.jpg and so on.

The program waits 60 seconds to read the next image from the folder. If no new image has been uploaded to the folder, the program stops running. You can change this time (the time the program waits for a new image to be uploaded to the folder) to be the time you want by changing the waitMax variable (found in "short_main" in line 9).

The maximum number of images that the program processes is one number less than the number found in the while loop in "short_main" in line 11. Currently, my program says: "while k<6", so that’s mean that the program will read and process a maximum of 5 images.

You need to know that you need to change lines 4,5 and 9 in the "steps_function" function to make it right for you.

Two changes are required to download from a google drive.

1) Set the privilege to Anyone with the link for the file using the triple dots

2) Given a filename of below format: tweak- file/d to uc?export=download&id= while removing /view?usp=sharing

https://drive.google.com/file/d/1RbPkr6KxZCuv_d4c0q5DONooqHArxoS0/view?usp=sharing tweak it to

https://drive.google.com/uc?export=download&id=1RbPkr6KxZCuv_d4c0q5DONooqHArxoS0

if resourcekey=RESOURCE_KEY exists then also include at the end per Overleaf

Works for urlwrite and imread

urlwrite('https://drive.google.com/uc?export=download&id=1v3GsGgP3p905wzdvUqypL_-djYmxiyzK','2.png');

img=imread('https://drive.google.com/uc?export=download&id=1v3GsGgP3p905wzdvUqypL_-djYmxiyzK','png')

img2=imread('https://drive.google.com/uc?export=download&id=1v3GsGgP3p905wzdvUqypL_-djYmxiyzK');
