yes, the API for image recognition changed and we need to update the examples. It will be done.

@me-no-dev Thank you. I can add a little bit of info to this issue. Under Arduino IDE 2.0.0.rc5 and Arduino IDE 1.8.19
If you enable face detection or recognition by either one or both of the following #define

#define CONFIG_ESP_FACE_DETECT_ENABLED 1
#define CONFIG_ESP_FACE_RECOGNITION_ENABLED 1

causes 2 files to be included that do not exist
In the file app_httpd.cpp starting at 34

#if CONFIG_ESP_FACE_DETECT_ENABLED

#include "fd_forward.h"

#if CONFIG_ESP_FACE_RECOGNITION_ENABLED
#include "fr_forward.h"

#define ENROLL_CONFIRM_TIMES 5
#define FACE_ID_SAVE_NUMBER 7
#endif

Those files where #included in earlier versions of the sample, but it appears that the files where never placed in the sample directory. Looks like they existed somewhere in the face detection library. I've briefly looked for they the espressif github repo but came up empty. I will continue searching as my active project uses face detection and when I moved to 2.0.2 to get working I2C functionality, face detection broke.

Am happy to help any way I can. I've got 4 or 5 of the cam modules various types.
