In 2018-07, I failed to post a picture by BlueStacks, due to a software fault: The pictures from the smartphone “Gallery” were postet as “black” photos .
In Chrome, go to Instagram.com and sign in. Now right-click the page > Inspect > click the Tablet icon (top-left). The page should switch to mobile view, where you'll find a camera button at the bottom of the screen, which lets you upload a photo from your desktop”.
You may upload up to 10 photos from your smartphone to an Instagram album.
16:9 landscape photos taken by a smartphone are cut to a square photo, so left and right part of you photos are missing .
The smartphone app creates a folder named “Instagram” with a copy of all selected photos on the filesystem of your smartphone?!
TwentyBN "The 20BN-jester Dataset V1" - “The 20BN-JESTER dataset is a large collection of densely-labeled video clips that show humans performing pre-definded hand gestures in front of a laptop camera or webcam. The dataset was created by a large number of crowd workers. It allows for training robust machine learning models to recognize human hand gestures. It is available free of charge for academic research”.
TwentyBN "The 20BN-something-something Dataset V2 " - “The 20BN-SOMETHING-SOMETHING dataset is a large collection of densely-labeled video clips that show humans performing pre-defined basic actions with everyday objects. The dataset was created by a large number of crowd workers. It allows machine learning models to develop fine-grained understanding of basic actions that occur in the physical world. It is available free of charge for academic research”.
TwentyBN "Data" - “The Leading Video Repository for Training Neural Networks”.
Experts told me: Video platforms are not suitable for image recognition learning. TwentyBN's technical trick & business model: Inverse labeling of videos. Don´t detect an object in a given video of a video platform, but let the crowd community generate and provide videos with the wanted object.
