Overview of preprocessing conditions (filtering and scaling) for evaluation of plant image registration using FP, PC and INT methods. 35 scale steps in the range between [0.3, 1.0] (step size = 0.02) were probed with original (a) and manually segmented (b) FLU/VIS images. Since registration routines require grayscale images, RGB images are converted to grayscale (c). In addition, registration is performed with color-edge FLU/VIS images (d)
