About 4K🌻Photo


Welcome to the nice world of AppleTV apps. Started as a learning and hobbyist project 4K Photo is the perfect companion app for you AppleTV when browsing or presenting your Photo Library.

Features

  • Browse your iCloud Photo Library on a AppleTV with tvOS
  • Use Computer Vision with CoreML all local on your AppleTV to detect the category of your images.
  • Double Tap to Zoom: Zoom into the image with a configurable zoom factor from 1.5x up to 3.0x
  • Display GPS and Map Geolocation Data as an overlay image when your image has this embedded metadata
  • Correct sort order of Photostream in ascending way









Computer Vision Image Detection based on Machine Learning


With the powerful GPUs even in small devices like an AppleTV I leveraged CoreML with the capabilites of Machine Learning to identify your image categories.

  • Automatic image detection with ResNet50 neural network up to three categories. You get tags on the info panel, when the probbability is higher than 15 percent.
  • Sometimes this leads to funny unexpected results, but the calculaton is usually done in less than 50[ms]. That´s near realtime.
  • I tried different models, but for typical photos the model ResNet50 gave me the best results. Please stay tuned for more updates, when Apple and the community releases more libraries. Just be safe: The processing is only done on your device. I don´t sent back any data for the Computer Vision.










Bringing the same experience you would expect from your iPhone or iPad

Dynamic Zoom


You will never miss a detail. With dynamic zoom you can display all the details in your images.

See the images in a new perspective: Overview of the whole image or drilled down to the last detail.

  • Dynamic Zoom Feature: Display the image at 100% to get an overview
  • Double Tap to Zoom: Zoom into the image with a configurable zoom factor from 1.5x up to 3.0x
  • Scroll in the zoomed image with the remote control touch pad
  • Support for different aspect ratios including 1:1 and panoramic scenery









Zoom deeper with 3.0x factor

Ususally the viewing experience stops with the size of your television set. Sometimes you want to see more details.

You slighty double tap on your AppleTV Remote and zoom into your photos for more details. Wow - that´s resolution!
