- Hemispherical photography is a well-established method to optically assess ecological parameters related to plant canopies; e.g. ground-level light regimes and the distribution of foliage within the crown space. Interpreting hemispherical photographs involves classifying pixels as either sky or vegetation. A wide range of automatic thresholding or binarization algorithms …

- As the photograph taken by such a lens is the projection of a hemisphere in front of it on to a flat plate, they are commonly known as hemispherical photographs (hereafter termed “photographs”), as illustrated in Fig. 1. Such a photograph is possible if the camera eye is opened to a denser medium followed by a less dense medium, very similar to how fishes view the …

- Hemispherical photos can fit into any standard spatial sampling scheme (e.g. transects, grid, opportunistic, clustered, etc.) depending on your downstream statistical analysis. However, because hemispherical photos capture such a wide angle of view, you must be careful of any analysis that assumes independence of observations if the viewshed overlaps between …

- Bio. CV. Analyzing Hemispherical Photos. February 3, 2019 July 16, 2021 [email protected]. Now that you’ve got the theory, equipment, and your own hemispherical photos, the final steps are processing the photos and generating estimates of canopy and light values. We’ll be correcting photos and then converting to a binary image for analysis just like …

- https://cfs.nrcan.gc.ca/publications?id=38831
- Hemispherical photography (HP) is a field-based technique to acquire and assess photographs of plant and tree canopies. HP is of considerable interest to the forest and ecological communities because of its ability to describe the penetration of the sun’s energy into the forest canopy and its effects on vegetation composition and structure.

- Hemispherical photographs (HPs) are taken with a fisheye lens and the camera typically pointed upwards to capture canopy geometry. The fraction of visible sky through the canopy (i.e. gap fraction) can be calculated from HPs and used to document key canopy properties such as canopy openness (CO) and infer effective leaf area index (LAI; Gonsamo et …
