Image Classification in Machine Learning [Intro + Tutorial]

#artificialintelligence

Image Classification is one of the most fundamental tasks in computer vision. It has revolutionized and propelled technological advancements in the most prominent fields, including the automobile industry, healthcare, manufacturing, and more. How does Image Classification work, and what are its benefits and limitations? Keep reading, and in the next few minutes, you'll learn the following: Image Classification (often referred to as Image Recognition) is the task of associating one (single-label classification) or more (multi-label classification) labels to a given image. Here's how it looks like in practice when classifying different birds-- images are tagged using V7. Image Classification is a solid task to benchmark modern architectures and methodologies in the domain of computer vision. Now let's briefly discuss two types of Image Classification, depending on the complexity of the classification task at hand. Single-label classification is the most common classification task in supervised Image Classification.


Real Time Image Segmentation Using 5 Lines of Code - KDnuggets

#artificialintelligence

Image segmentation is an aspect of computer vision that deals with segmenting the contents of objects visualized by a computer into different categories for better analysis. The contributions of image segmentation in solving a lot of computer vision problems such as analysis of medical images, background editing, vision in self driving cars and analysis of satellite images make it an invaluable field in computer vision. One of the greatest challenges in computer vision is keeping the space between accuracy and speed performance for real time applications. In the field of computer vision there is this dilemma of a computer vision solution either being more accurate and slow or less accurate and faster. PixelLib Library is a library created to allow easy integration of object segmentation in images and videos using few lines of python code.


How 10 Skin Tones Will Reshape Google's Approach to AI

WIRED

For years, tech companies have relied on something called the Fitzpatrick scale to classify skin tones for their computer vision algorithms. Originally designed for dermatologists in the 1970s, the system comprises only six skin tones, a possible contributor to AI's well-documented failures in identifying people of color. Now Google is beginning to incorporate a 10-skin tone standard across its products, called the Monk Skin Tone (MST) scale, from Google Search Images to Google Photos and beyond. The development has the potential to reduce bias in data sets used to train AI in everything from health care to content moderation. Google first signaled plans to go beyond the Fitzpatrick scale last year; internally, the project dates back to a summer 2020 effort to make AI "work better for people of color," according to a Twitter thread from Xango Eyeé, a responsible AI product manager at the company.


AI recognition of patient race in medical imaging: a modelling study

#artificialintelligence

Previous studies in medical imaging have shown disparate abilities of artificial intelligence (AI) to detect a person's race, yet there is no known correlation for race on medical imaging that would be obvious to human experts when interpreting the images. We aimed to conduct a comprehensive evaluation of the ability of AI to recognise a patient's racial identity from medical images. Using private (Emory CXR, Emory Chest CT, Emory Cervical Spine, and Emory Mammogram) and public (MIMIC-CXR, CheXpert, National Lung Cancer Screening Trial, RSNA Pulmonary Embolism CT, and Digital Hand Atlas) datasets, we evaluated, first, performance quantification of deep learning models in detecting race from medical images, including the ability of these models to generalise to external environments and across multiple imaging modalities. Second, we assessed possible confounding of anatomic and phenotypic population features by assessing the ability of these hypothesised confounders to detect race in isolation using regression models, and by re-evaluating the deep learning models by testing them on datasets stratified by these hypothesised confounding variables. Last, by exploring the effect of image corruptions on model performance, we investigated the underlying mechanism by which AI models can recognise race.


Perceptron AI Roundup: Bias, computer vision and wave action – TechCrunch

#artificialintelligence

Research in the field of machine learning and AI, now a key technology in practically every industry and company, is far too voluminous for anyone to read it all. This column, Perceptron (previously Deep Science), aims to collect some of the most relevant recent discoveries and papers -- particularly in, but not limited to, artificial intelligence -- and explain why they matter. This week in AI, a new study reveals how bias, a common problem in AI systems, can start with the instructions given to the people recruited to annotate data from which AI systems learn to make predictions. The co-authors find that annotators pick up on patterns in the instructions, which condition them to contribute annotations that then become over-represented in the data, biasing the AI system toward these annotations. Many AI systems today "learn" to make sense of images, videos, text and audio from examples that have been labeled by annotators.

Image Classification model by Microsoft Lobe in Power Apps – Part 1

#artificialintelligence

With the growth in technology we have seen an incline towards the technologies related to Machine Learning and Artificial Intelligence in our day-to-day life. In recent few years Microsoft has been pushing Low-Code/ No-Code ideology and have been incorporating ML and AI technologies in their PCF control, AI Builder Models, etc. Evidence of this can be seen in the recent PCF control like Business card Scanner, Document Automation models, etc. In this blog series, we will be seeing the Image classification model by Lobe which is currently in preview. Microsoft Lobe is a free desktop application provided by Microsoft which can be used to classify Images into labels.


Machine Learning and Deep Learning with OpenCV

#artificialintelligence

Machine Learning and Deep learning techniques, in particular, are changing the way computers see and interact with the World. From augmented and mixed-reality applications to just gathering data, these new techniques are revolutionizing a lot of industries. OpenCV is a cross-platform library using which we can develop real-time computer vision applications. It mainly focuses on image processing, video capture, and analysis including features like face detection and object detection. This course is designed to give you a hands-on learning experience by going from the basic concepts to the most current in-depth Deep Learning methods for Computer Vision in use today.
