“…PCA was also helpful in detecting the correlations between traits, as well as recognizing the independent principle components that are effective on plant attributes and assessing diversity [ 58 ]. Moreover, PCA is a well-known dimension reduction approach for condensing a big collection of variables into a small set that retains the majority of the information from the large set [ 59 ]. It reflects the importance of the largest contributor to the total variation at each axis of differentiation [ 60 ].…”

“…The combination of images provided by sensors operating at different bandwidths, such as thermal and visible, is a particularly challenging case for pixel-based fusion methods since the opposite contrast issue must be addressed in order to generate and to display the fused images. Techniques based on principal component analysis 4,15 , discrete wavelet transform 16,17,18 , opponent color contrast 7,19 or on Retinex algorithm 5 may be used for that purpose. For completely autonomous applications, the implementation of such methods may be avoided since there is no need to display new images that make human perception easier.…”

“…Industry and academia efforts over the past few years have shown that combination of multi-spectral imagery can be either beneficial or detrimental, depending upon which source provides what information at which time [3][4][5][6][7][8][9][10][11][12]. In order to maximize benefit from the available information, a statistical relationship between the image sources must be derived such that the corresponding pixel amplitudes may be combined by some desired mathematical principal.…”
