Study Notes
Upscaling (Super-resolution)
- Super resolution uses machine learning algorithms to enhance image resolution by analyzing and adding new pixels while maintaining sharpness.
- Interpolation algorithms infer new pixel data by examining neighboring pixels and duplicating content to fill in blanks.
Denoising
- Denoising involves removing noise from images to enhance quality using advanced algorithms.
- Types of lighting conditions considered in denoising include:
- Diffuse: Scattered lighting reflected from surfaces.
- Specular: Reflections where light is directed in specific directions.
- Infinite light-source shadows: Shadows cast by sunlight and other visible light sources.
Fractal Compression
- A lossy compression method based on fractals, suitable for textures and natural images.
- Fractal compression exploits similarities within parts of an image to create mathematical data called "fractal codes," which are used to reconstruct the original image.
Convolutional Neural Network
- Comprehension of convolutional neural networks (CNNs) is often aided by educational videos that illustrate their function within AI deep learning systems.
Dataset
- Datasets are essential for AI development, comprising curated and labeled images that help train algorithms.
- Key factors for datasets in photo resolution enhancement include:
- High-resolution images.
- Low-resolution correspondences for training.
- Diversity in content to improve generalization.
- Size and quantity of data to support robust training.
- Realistic challenges to better simulate real-world scenarios.
Backpropagation
- Backpropagation is a training process for neural networks that adjusts weights based on the error rate from forward propagation.
- This technique enables deep neural networks to perform tasks such as image recognition and natural language processing.
