I want to train a custom object detection model (hand detection).
I tried using Tensorflow’s Colab but it is not detecting any thing.
I used it in my android app but it says model is not compatible with ml kit library.
so can I make this model compatible with ml kit?
or how can I train a new model which is compatible with ml kit.
Thank you!
@Abdullah_Ilyas Welcome to tensorflow forum!
While your existing model not compatible with ML Kit might not work immediately, there are options to make it compatible or train a new model specifically for ML Kit.
Making your existing model compatible with ML Kit:
- Quantization: Quantize your model from FP32 to TFLite format.
- Model conversion: Use the TensorFlow Lite Converter to convert your TFLite model to a format compatible with ML Kit.
- Model optimization: Optimize the TFLite model for on-device inference using techniques like quantization-aware training or pruning.
- Input and output compatibility: Ensure your model’s input and output formats are compatible with ML Kit’s input image format and expected output format for hand detection.
Training a new model compatible with ML Kit:
- Choose a compatible model architecture: Select a model architecture supported by ML Kit, such as MobileNet v2 or EfficientNet.
- Pre-trained weights: Use pre-trained weights for the chosen architecture available on TensorFlow Hub.
- Custom training: Fine-tune the pre-trained model on your hand detection dataset using the TensorFlow Object Detection API.
- Export to TFLite: Export the trained model to TFLite format using the TensorFlow Lite Converter.
- Optimize for on-device inference: Apply optimization techniques like quantization-aware training or pruning to the TFLite model.

Specific considerations for hand detection:
- Ensure your training data includes diverse hand poses, positions, and lighting conditions.
- Adjust the model’s input size and resolution based on the desired hand detection accuracy and performance on your device.
- Consider using data augmentation techniques like random cropping and flipping to improve the model’sgeneralizability.
