Most of my subjects allows taking a picture of our lecture from a blackboard, because of this I took advantage of it and take a picture of all the lectures that we have.

Yesterday my professor said that we can open all notes except notes from our phone. Because of this, I am not able to open any kind of notes that I have from a phone.

Question: Is there an application where I can convert a picture of our lecture to text so I can print it?

Printing the picture is possible but it can have a great impact on the ink of my printer.

Example of picture lecture:

Sample panorama photo Sample picture of a lecture

Actual Photo Actual Photo of lecture

Edit: I am taking a picture using android 6.0 lollipop (Android One phone) and I have a desktop PC windows 8 and 10.

Bonus: If my account permits, I am willing to give +50 points to anyone that can consider physics formula. There are lectures that I've got from physics or math subjects.

    I would look into OCR software, it may; though, be difficult to do this with human handwriting

    Alright, I won't add an answer, it seems that it can only read separated individual characters and looking at the picture, I think it may have a hard time with that.

    ok, one more recommendation I'll try, please tell me if this works out, Infty Reader, it seems capable of both handwritten notes and mathematical formulas

Nice Inftyreader software. Personally I would just Photoshop and invert the pics or Color Range Select "White" then cut and paste on a black background then invert. Like these I did to your pics.

  • This does not convert the image to text

    Discable, please link to the software, see its price, and describe the steps to make it do what the asker wants. Also, please clearly seperate from the Photoshop answer.
