Attached video shows computer vision measurments of a basil plant over a 30 day period. The goal was to understand computer vision performance for the LED plant biofeedhack system. Images show the ability of computer vision to measure small features less than 1mm without contact. The next step is to regulate the LED grow lights with data collected from the computer vision measurements. Thanks for following and special thanks for those who 'liked' the project!

Computer vision software (SimpleCV) extracts basil plant ‘blob’ features from soil background and counts number of pixels in each plant ’blob’. Picture info: Unprocesssed Image (right), computer vision processed image (left) marks counted pixels in green. Text below displays # of pixels in area/ length/width and perimeter for each image. Images are scaled/calibrated by ruler - 1 pixel measures .6mm x .6mm.
