THE OFFICE (working title), 2019
Humans and plants live on different timescales. This is certainly one of the reasons why in everyday life, plants might often seem static and object-like to us. »The Office« (2019) makes use of existing video footage that covers large time spans, in this case, popular long-term tv shows. These productions showcase office and apartment interiors over a longer period of time, often also including houseplants which are mainly used for decorative purposes. Some of these series run over years or even decades and thus comprise many hours of footage. Convolutional neural networks are used as a tool to detect scenes involving houseplants while processing large quantities of the given video material. Selected scenes are compiled into a time-lapse movie which documents plant growth over a long period of time. While the lively movement and growth of the normally passively seeming plants becomes visible, the human activities become blurry and fade into the background.
Keywords: plants, plant-human-relationships, time, timescales, time-lapse, video, neural networks

Technische Umsetzung

Erste Schritte

• Convolutional Neural Networks for object detection (in videos)
• Heartbeat Tutorial Part 1: Detecting objects in videos and camera feeds using Keras, OpenCV, and ImageAI
  • using a Python library called ImageAi
  • using a pretrained YOLOv3 computer vision model that can recognize 80 different objects, including "potted plants"
  • TO DO: installing a number of python libraries and ImageAi
• Heartbeat Tutorial Part 2: Analyze and Visualize Detected Video Objects Using Keras and ImageAI

Aktueller Stand

Working with the pretrained network

• analyze video frame by frame (works for example with .mp4 and .m4v)
• detect custom objects, in this case of the category "potted plant"
• output a list called "detected frames" that for each frame in the video contains either a 0 or 1 to indicate whether a plant has or has not been detected in that frame. For example (for a video with 24 frames):

[0, 0, 0, 0, 0, 1, 1, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 1, 0, 0, 0, 0]

• transform list into a numpy array
• transform this array into another array called "changeArray" only indicates the positions where something changes in the array (if values jump from 0 to 1, or from 1 to 0 or in other words detect the beginning and end of the plant sequence
