Computer OS: Mac OSX

Description:

Using the example "CameraWebServer" sketch no logs are appearing to see if Face Detection is working or not

Debug Messages:

WiFi connected
Camera Ready! Use 'http://192.168.1.234' to connect

I think the "fd_forward.h" and "fr_forward.h" aren't being found, when trying to include them

example_sketch_fd:7:10: fatal error: fd_forward.h: No such file or directory
 #include "fd_forward.h"
          ^~~~~~~~~~~~~~
compilation terminated.
exit status 1
fd_forward.h: No such file or directory

Correct since face defection is not included in the core 2.0.1 build

@Jason2866 is there a plan to implement it or is it gone for good? If so what does that timeline look like?

CameraWebServer example

#if CONFIG_ESP_FACE_DETECT_ENABLED

#include "fd_forward.h"

#if CONFIG_ESP_FACE_RECOGNITION_ENABLED
#include "fr_forward.h"

This is a question for the maintainers. I just do a modified Arduino framework for Project Tasmota with the https://github.com/espressif/esp32-arduino-lib-builder and noticed in this process that there is no more a compatible Face Detection version for IDF4.4 It is replaced by https://github.com/espressif/esp-dl which is not implemented in Arduino at the moment.
@me-no-dev Are there plans for?

@Jason2866 I also recently noticed this. Surely will take a look at it and fix it at some point :)

@me-no-dev - You are amazing! If you can let me know as I am building PoC based of example code and parts. Was shocked when it stopped working.

I guess for now I can downgrade to re-enable functionality?

@Jason2866 - Thank you for the info.

Sorry to revive this thread, I tried v2.0.1 and added #define CONFIG_ESP_FACE_DETECT_ENABLED 1 to app_httpd.cpp, face detection works but it has no output in serial monitor, also, what does face recognition do? I press enroll face when a face is detected with a rectangle but I think it does nothing to enroll it.
Edit: similarly to face detect I had to enable face recognition :D #define CONFIG_ESP_FACE_RECOGNITION_ENABLED 1 it works!

@chepo92 You have not used core v2.0.1 in this case, there is no fd_forward.h and fr_forward.h in core 2.0.x

You were right, i checked pio output and it is using framework-arduinoespressif32 3.10006.210326 (1.0.6)

hey doubling back on this topic seeing if there is a way i can get involved to help. I would really like to see this feature or something similar in the newer version or a submodule for it. let me know how i can get involved.
