Study Notes
Image Classification
- Involves categorizing images into groups based on content using machine learning algorithms.
- Deep Learning models like Convolutional Neural Networks (CNNs) are essential for identifying patterns.
- Common applications include auto-flagging violative content on social networks and dating apps.
- Supervised classification requires AI to learn from labeled samples, while unsupervised classification analyzes data without prior examples.
- CNNs minimize preprocessing, making them ideal for tackling complex images.
- K-Nearest Neighbors (KNN) estimates classifications based on “neighbors,” while Support Vector Machines (SVM) create distinct boundaries between categories.
- Random Forests utilize multiple decision trees for better accuracy, while Deep Belief Networks (DBNs) use multiple layers of unsupervised learning for deeper insights.
Object Detection
- Aims to localize and classify objects within images using neural networks.
- Has applications across various fields including medical imaging and autonomous vehicles.
- Utilizes CNNs, notably R-CNN and YOLO, for training on object detection, classification, and segmentation models.
- Recent advancements include the focus on 3D images and video object detection.
- Challenges exist such as motion blur and shifting camera focus that complicate object identification across video frames.
Semantic Segmentation
- Assigns class labels to individual pixels in an image through deep learning algorithms.
- Offers a more refined understanding of visual information compared to image classification.
- Distinguishes itself within image segmentation, which also includes instance segmentation and panoptic segmentation.
- Provides precise locations for different visual information, indicating where each segment begins and ends.
- Notable open-source datasets for segmentation include:
- Pascal Visual Object Classes (Pascal VOC), featuring various object classes and segmentation maps.
- MS COCO, comprising around 330,000 images with multi-faceted annotations for diverse tasks.
- Cityscapes dataset includes 5,000 urban images with extensive annotations and class labels.
AI in Media Restoration
- AI is employed in renewing old opera footage by upscaling and enhancing visuals.
- Reviving classic films and shows using AI is a growing trend to attract modern audiences.
- Many classic films have undergone recoloring and re-sounding to increase their appeal.
- Utilizing AI in film restoration is cost-effective and less labor-intensive, revitalizing timeless classics for contemporary viewers.
