Data Augmentation & Preprocessing

Image Augmentation

The dataset was augmented using Keras's ImageDataGenerator to enhance diversity and robustness. Below are the parameters used for augmentation:

from keras.preprocessing.image import ImageDataGenerator

datagen = ImageDataGenerator(
    rotation_range=10,
    width_shift_range=0.1,
    height_shift_range=0.1,
    shear_range=0.1,
    zoom_range=0.1,
    horizontal_flip=True,
    fill_mode='nearest',
    brightness_range=[0.2, 1.2]
)

The augmentations include:

•	Rotation: Up to 10 degrees.
•	Width & Height Shift: Up to 10% of the total image size.
•	Shearing & Zooming: 10% variation.
•	Horizontal Flip: Randomly flips images for additional diversity.
•	Brightness Adjustment: Ranges from 0.2 to 1.2 for varying light conditions.

Image Cropping

•	All images were resized to a consistent 224x225 pixels
