16. Law Enforcement and Public Safety Washington County Sheriff (OR) To follow leads from citizens & security cameras, a person spends days manually searching thousands of images The mobile and web app powered by Amazon Rekognition compares new images with photos of previous offenders: Helps identify unknown theft suspects from security footage Provides leads by identifying possible witnesses & accomplices Identifies persons of interest who do not have identification

17. Travel and Hospitality Anticipatory guest experiences for hotels using Amazon Rekognition for facial recognition and sentiment capture Kaliber is using Amazon Rekognition to help front desk agents enhance relationships with guests: Recognize guests early for instant and personalized service Receive rich, contextualized guest information in real time Track guest sentiment throughout their stay Drive an 80% increase in guest satisfaction scores

18. Guest Workflow Walk in Be recognized Be greeted Capture sentiment to trigger actionsEnjoy personalized serviceLeave with a fond farewell Kaliber allows us to bond with our guests from the second they walk in my hotel. GM of a 5-star property

19. hotel Simplified Architecture One master guest collection enables single-workflow deployment across all properties Guest recognition triggers real-time information retrieval Automated pipeline processing in AWS improves reliability Automated image sampling constantly improves recognition quality

20. Influencer Marketing Associate influencers with objects and scenes in social media images in order to create high impact campaigns for clients Using Amazon Rekognition for metadata extraction: Create rich media indexes of images from social media feeds, which the application associates with influencers Enable analytics to profile environments where influence is strongest Connect client brands with the influencers most likely to have impact

21. Media and Entertainment Identify who is on camera for each of 8 networks so that recorded video can be indexed and searched Video frame-sampling facial recognition solution using Amazon Rekognition: Indexed 97,000 people into a face collection in 1 day Sample frames every 6 secs and test for image variance Upload images to Amazon S3 and call Amazon Rekognition to find best facial match Store time stamp and faceID metadata

22. C-SPAN Indexing Architecture Video feeds encoded from 8 locations (3 networks and 5 federal courthouses) Frames extracted into JPGs and hosted in Amazon S3 Amazon SQS provides asynchronous decoupling Search Amazon Rekognition collection for high similarity matches Results cache drives search and discovery requests R3 hashing detects if a scene significantly changes

24. Amazon Rekognition for Media Metadata Generation Shane Murphy, Cloud Solutions Engineer Mark Kelly, Director Cloud Operations

25. Company Background Scripps Networks Interactive Lifestyle Media Develop web and video content for distribution to international audiences in 6 continents 190 million+ consumers each month Dozens of digital platforms, hundreds of thousands of images, and petabytes of video. 2016: Digital content grew 700% 2017: Will produce 2,500 hours of linear television content

26. Media Metadata Attributes Easy Size, resolution, name, etc. Harder Classification. Room type, color scheme, brand category, furniture style, etc. Must be fast Must be good (enough)

27. Problem Description Media management is core to our business. Manually creating metadata is time intensive, tedious, and expensive. Automation is amazing! But how?

28. Classification - Current State Cutting edge neural networks Example MIT Places for Scene Recognition http://places.csail.mit.edu/ Complicated, bloated, computationally infeasible, static Only one problem type, but we have many classes to identify

29. Lets Simplify! Our Strategy Divide and Conquer 1. Use Amazon Rekognition to generate text labels for easy processing 2. Use supervised machine learning to train multiple predictive models 3. Set up multiple fan-out pipelines for automated classification workloads

30. Amazon Rekognition Step 1: Generate Labels Python (boto3) example for img in training_images: labels= rekognize.detect_labels ( Image = { 'S3Object' : { 'Bucket' : SOURCE_BUCKET, 'Name' : img} }, MinConfidence = MIN_CONFIDENCE)['Labels'] labels[0] = 'Plant Potted Plant Furniture Indoors Interior Design Room Kitchen

31. Step 2a: Transform Labels Plant Room Table Lamp Furniture AttributeN Image0 2 1 0 1 2 Image1 1 3 1 1 0 Image2 1 1 1 0 1 Bag of Words

32. Step 2b Derive Relationships Split the training data, use most of it to train, some to test Options - Decision trees, random forest, k nearest neighbors, multinomial logistic regression Specifics determined by problem description and tuning (art and science)

33. Step 3 Predict New Metadata Input Labels = Plant Potted Plant Indoors Interior Design Room Bedroom Lamp Lampshade Table Lamp Apartment Housing Lighting Dining Room Shelf Furniture Table Tabletop Dining Room

34. Lets Simplify! Strategy Transform to easier use case Sample video frames -> feed through Amazon Rekognition, classifiers, and other analysis engines and parsers

35. Use Case Fanout Video Pipeline Amazon Rekognition Amazon Elasticsearch Service Amazon S3

36. So what? Room type classification initial results 75% accurate Immediate savings in image and video classification: $500,000 Time to market thousands of hours saved per year Content Grouping and Dynamic Generation

37. Challenges in Our Approach Integration with Amazon Machine Learning Lack of Optical Character Recognition Model Management and Lifecycles Real time generation

38. Future Directions Revenue Opportunities!!! Product placement, logos, etc. Facial Recognition Landmark Detection Cultural Sensitivity Compliance and Terms of Service
