We found that plants emit sounds, and that stressed plants—both drought-stressed (Dry) and cut plants (Cut; see STAR Methods)—emit significantly more sounds than plants of any of the control groups (p < e−6, Wilcoxon test for each of the 12 comparisons with Holm-Bonferroni correction). Three controls were used for each plant species and treatment: recording […]

gyroflow/gyroflow: Video stabilization using gyroscope data

Gyroflow is an application that can stabilize your video by using motion data from a gyroscope and optionally an accelerometer. Modern cameras record that data internally (GoPro, Sony, Insta360 etc), and this application stabilizes the captured footage precisely by using them. It can also use gyro data from an external source (eg. from Betaflight blackbox). […]
