ESP32 Camera Module Initialization Failure in Image Recognition System for Tissue Samples

@Boss lady The "Camera initialization failed" error typically means there's a mismatch in your pin configuration or the camera module isn't properly connected. You should verify Pin connections, ensure proper power supply, check camera module compatibility and update ur code with the neccesary pin configurations
