LACMUS TFLITE OBJECT DETECTION

Image preprocessing pipeline

Vision_API_data_prepare.ipynb

1. Select CROP_SIZE prior to the model input (512 for EfficientDetLiteB3).
2. Select the number of windows on each axis H, W (default 3x4).
3. The original images are compressed to a (HCROP_SIZE, WCROP_SIZE) (1536x2048).
4. Crop images and save it to the TESTcrops, TRAINcrops dirs.
5. Normalized boxes annotation saved at vision.csv.
