Analyze Text With Azure AI Language

By Ashwin Venugopal -

  Introduction Language models are used by Natural Language Processing (NLP) systems to decipher spoken or written language's semantic meaning. You can create language models for your apps using the Language Understanding service. The world produces enormous amounts of data every day, much of which is text-based and may be found in emails, social media posts, online reviews, corporate papers, and more. You can develop apps that derive meaning and insights from this text-based data by using artificial intelligence approaches that use statistical and semantic models. The Azure AI Language provides an API for common text analysis techniques that you can easily integrate into your own application code. Provision an Azure AI Language Resource Azure AI Language is designed to help you extract information from text. It provides functionality that you can use for: Language Detection - determining the language in which text is written. Key Phrase Extraction - identifying importa...

  Use Video Analyzer Widgets & APIs Although the Azure Video Indexer site allows you to complete all video analysis activities, you might want to integrate the service into unique applications. You can do this in two different ways: Azure Video Indexer Widgets Although the Azure Video Indexer site allows you to complete all video analysis activities, you might want to integrate the service into unique applications. You can do this in two different ways. Azure Video Indexer API Azure Video Indexer provides a REST API that you can use to obtain information about your account, including an access token. You can then use your token to consume the REST API and automate video indexing tasks, creating projects, retrieving insights, and creating or deleting custom models. Deploy With ARM Template Azure Resource Manager (ARM) templates are available to create the Azure AI Video Indexer resource in your subscription, based on the parameters specified in the template file.

Analyze Video (Part 1)

By Ashwin Venugopal -
Image
  Overview Producing material in video format is becoming more and more prevalent for both individuals and companies. For instance, you might record a teleconference that includes webcam footage and slide or document presentations, or you might use a cellphone to record a live event. Because of this, video files include a lot of information that may need to be extracted for analysis or to facilitate indexing for searchability. Azure Video Indexer is a service that extracts information from videos, such as scene segmentation, item labels, word recognition, face identification, and more. Understand Azure Video Indexer Capabilities The Azure Video Indexer service is designed to help you extract information from videos. It provides functionality that you can use for: Facial recognition - detecting the presence of individual people in the image. This requires Access approval. Optical character recognition - reading text in the video. Speech transcription - creating a text transcript ...

Read Text With Azure AI Vision Service

By Ashwin Venugopal -
Image
  Introduction Azure's AI Vision service uses algorithms to process images and return information. Let's say you are tasked with transferring the text from thousands of photos to a computer database. The text in the scanned photos is multilingual and arranged in several formats. How do you ensure that the data is input accurately while finishing the project in a fair amount of time? Every day, businesses all across the world deal with similar situations. The project would be difficult to finish without AI services, particularly if its scope changed. We can use Optical Character Recognition (OCR) and handle this project as an Azure AI Vision scenario using AI services. OCR enables you to extract text from documents, including handwritten or unstructured papers, as well as from photographs, such as pictures of products and street signs. Machine learning models must be trained to address a wide range of use cases in order to create an automated AI solution.  The Azure AI Vision ...

Detect Faces With Azure AI Vision Service

By Ashwin Venugopal -
Image
  Understand Capabilities Of The Face Service The Face service provides comprehensive facial detection, analysis, and recognition capabilities. The Face service provides functionality that you can use for: Face detection - for each detected face, the results include an ID that identifies the face and the bounding box coordinates indicating its location in the image. Face attribute analysis - you can return a wide range of facial attributes, including- Head pose (pitch, roll, and yaw orientation in 3D space) Glasses (NoGlasses, ReadingGlasses, Sunglasses, or Swimming Goggles) Blur (low, medium, or high) Exposure (underExposure, goodExposure, or overExposure) Noise (visual noise in the image) Occlusion (objects obscuring the face) Accessories (glasses, headwear, mask) QualityForRecognition (low, medium, or high) Facial landmark location - coordinates for key landmarks in relation to facial features (for example, eye corners, pupils, tip of nose, and so on). Face comparison - you ...

Detect, Analyze, and Recognize Faces

By Ashwin Venugopal -
Image
  Introduction AI systems frequently face computer vision difficulties like face detection, analysis, and recognition. One of the main ways AI systems can behave like humans and develop empathy with users is by being able to recognize a person based on their facial traits, determine whether a person is present, or identify a person's facial position. Identify Options For Face Detection Analysis and Identification There are two Azure AI services that you can use to build solutions that detect faces or people in images. The Azure AI Vision Service The Azure AI Vision service enables you to detect people in an image, as well as returning a bounding box for its location. The Face Service The Face service offers more comprehensive facial analysis capabilities than the Azure AI Vision service, including: Face detection (with bounding box). Comprehensive facial feature analysis (including head pose, presence of spectacles, blur, facial landmarks, occlusion and others). Face comparison and...

Detect Objects In Images (Part 2)

By Ashwin Venugopal -
Image
  Train an Object Detector You can either utilize the REST API or SDK to build code that carries out the training activities, or you can use the Azure AI Custom Vision portal to upload and label photos prior to training, assessing, testing, and releasing the model. The labeling of the images with tags is the main distinction between training an object detection model and training an image classification model. Object detection necessitates that each label have a tag and a region that specifies the bounding box for each object in an image, whereas image classification requires one or more tags that apply to the entire image. You can label your training photos using the graphical interface offered by the Azure AI Custom Vision portal. Consider Options for Labeling Images The Azure AI Custom Vision portal's interactive interface is the simplest way to identify photos for object detection. By sliding the bounding box to enclose the object you wish to label, you can modify or add tags t...
