Set up the image classification environment in Google Colab by installing and importing key libraries: NumPy, pandas, matplotlib, OpenCV, TensorFlow, and Keras, while learning about virtual environments.
Explore how to create static, animated, and interactive visuals with Matplotlib in Python, including line, bar, and histogram plots, and learn to visualize data for image classification models.
Master basic image manipulations in Python using OpenCV to resize, crop, and rotate images, preparing data for image classification in the next chapter.
Build and evaluate a CNN-based image classifier with TensorFlow and Keras, detailing convolutional layers, ReLU, max pooling, flattening, dense layers, dropout, and softmax output.
Compile the model by setting the categorical cross entropy loss, Adam optimizer, and accuracy metric, then train for 20 epochs with batch size 64 and evaluate on the test set.
Address imbalanced data in image classification by computing and applying class weights to improve minority class performance and fairness, and explore hyperparameter tuning, learning rate adjustments, and regularization.
Welcome to "Introduction to Image Classification with Python: A Beginner's Guide"! This course is designed to provide you with a comprehensive understanding of image classification, an essential task in the field of machine learning and artificial intelligence.
