Deep Learning for Computer Vision

Basic and Advanced Computer Vision

Computer vision is an area of deep learning dedicated to interpreting and understanding images. It is used to help teach computers to “see” and to use visual information to perform visual tasks

Computer vision models are designed to translate visual data based on features and contextual information identified during training. This enables models to interpret images  and apply those interpretations to predictive or decision making tasks.

Image processing involves modifying or enhancing images to produce a new result. It can include optimizing brightness or contrast, increasing resolution, blurring sensitive information, or cropping. The difference between image processing and computer vision is that the former doesn’t necessarily require the identification of content.

Deep Learning is part of a broader family of machine learning methods based on artificial neural networks.

Deep-learning architectures such as deep neural networks,  recurrent neural networks, convolutional neural networks have been applied to fields including computer vision, speech recognition, natural language processing, machine translation, bioinformatics, drug design, medical image analysis, material inspection and board game programs, where they have produced good results

Artificial neural networks (ANNs) were inspired by information processing and distributed communication nodes in biological systems. ANNs have various differences from biological brains.

Keras is the most used deep learning framework. Keras follows best practices for reducing cognitive load: it offers APIs, it minimizes the number of user actions required for common use cases, and it provides clear & actionable error messages.
