ESP32 Forum

Hi,
My first post, and not sure if this is right place, sorry if it isnt.. I want to develop a remote camera based concept that has nothing to do with facial recognition, but I am struggling to find documentation/examples to help me.
What I need initially is to be able to put a grid on the screen. This must be possible as that's what the recognized face does when it draws box, but please how?
Having sorted that problem I would also like the ability to do my own SIMPLE computer vision (certainly nothing like OPENCV) by getting a Bitmap from camera and modifying pixel by pixel from/to array, before sending to server
And finally to get xy coordinates from the webpage of the mouse position with a button press to help with above.
Ideally solution would work in Arduino IDE but if not then I guess I'll come to terms with IDF.
I'm sure the above is generic enough to be of interest to many makers out there.
Any help greatly appreciated.

Hi Steve,
The two links could be helpful :
https://github.com/espressif/esp32-camera
https://github.com/espressif/esp-who/bl ... pp_httpd.c

You can get the image of some formats(JPEG, grayscale, YUV, RGB).

Thanks,
those links help me understand how to get cursor working, and Im sure with a bit more digging how to manipulate the image. It looks like it converts the image to BMP and puts into an array that the gfx library then renders. I have to say that a few more comments in code would be really helpful, fair enough if programmers dont comment own work, but it would certainly help others understand whats going on in examples if they did.
Thanks
Steve
