Computer vision lets AI understand images and videos. It's behind facial recognition, self-driving cars, medical imaging, and so much more. If you want to work with visual data, you need to understand computer vision.

What is Computer Vision?

Computer vision is the field of AI that trains computers to interpret and understand the visual world. Using digital images and videos, AI can identify and classify objects, detect faces, and even understand scenes.

Key Tasks

Image classification (what's in the image), object detection (where are objects), image segmentation (pixel-level understanding), and image generation. Each requires different techniques and models.

Convolutional Neural Networks

CNNs are the backbone of computer vision. They're designed to process pixel data and automatically learn features like edges, shapes, and objects. Understanding CNNs is essential for computer vision.

Real-World Applications

I'll show you practical examples - building image classifiers, detecting objects in images, and working with pre-trained models. These skills are in high demand and have countless applications.

Common Questions & Answers

What is computer vision?

Computer vision is an AI field that enables machines to interpret and understand visual information from images and videos. Tasks include image classification, object detection, face recognition, image segmentation, and scene understanding. CNNs are the primary deep learning architecture used.

Run Explain

import tensorflow as tf
from tensorflow import keras
from tensorflow.keras.applications import VGG16

# Use pre-trained model for image classification
base_model = VGG16(weights='imagenet', include_top=False, input_shape=(224, 224, 3))

# Add custom classification head
model = keras.Sequential([
    base_model,
    keras.layers.GlobalAveragePooling2D(),
    keras.layers.Dense(128, activation='relu'),
    keras.layers.Dense(10, activation='softmax')  # 10 classes
])

# For object detection, use models like YOLO or Faster R-CNN

How do Convolutional Neural Networks work?

CNNs use convolutional layers that apply filters to detect features like edges and patterns. Pooling layers reduce dimensions, and fully connected layers make final predictions. Convolution preserves spatial relationships, making CNNs ideal for images. They learn hierarchical features automatically.
