Abstract: Abstract. The use of time-lapse camera systems is becoming an increasingly popular method for data acquisition. The camera setup is often cost-effective and simple, allowing for a large amount of data to be accumulated over a variety of environments for relatively minimal effort. The acquired data can, with the correct post-processing, result in a wide range of useful quantitative and qualitative information in remote and dangerous areas. The post-processing requires a significant amount of steps to transform … Show more

“…Feature-tracking can be conducted by creating and tracking exclusively between each image pair in an image set (e.g., Messerli and Grinsted, 2015), or by tracking continuously through the image set using the same pixel-intensity features (e.g., James et al, 2016). Whilst tracking continuously enables the calculation of cumulative feature displacements, tracking between each image pair reduces the risk of error propagation from false matches.…”

“…When tracking between an image pair, the two images have been referred to in many ways, such as 'image A' and 'image B' (e.g., Messerli and Grinsted, 2015), and the 'reference' and 'destination'/'search' images (e.g., Ahn and Box, 2010;James et al, 2016). The terms reference image and destination image will be used subsequently; the reference image being where 5 points are seeded or templates are defined, and the destination image being where a point/template is matched to.…”
