From: Quantification of floating riverine macro-debris transport using an image processing approach
Images of the image processing flow steps of our algorithm. Panels (a–h) show the laboratory experiment and river monitoring, respectively. Panels (a) and (e) are the original images, (b) and (f) are the smoothed images, (c) and (g) are the difference images, and (d) and (h) are the binary images. The colour scale of the difference images is shown at the upper-right of panels (c) and (g). The red and blue boxes in panels (c) and (g) are the analysis and template planes shown in Fig. 6, respectively. The grey box in panel (h) is the calculated covered area.
