Claim 6:
7. The processor implemented method of claim 1 further comprising one or more of:
identifying, via the one or more hardware processors, an associated plant species based on the obtained one or more full leaves and similarity of leaf shapes using shape matching method-based Hu moments;
computing, via the one or more hardware processors, morphological features of the obtained one or more full leaves including i) ratio of leaf length to width of leaf calculated at the center of the leaf (ii) ratio of leaf length to the maximum width of the leaf (iii) ratio of bounding box area around a leaf to the area of the leaf (iv) color of a leaf in terms of ‘a’ and ‘b’ components on CieLab format;
receiving, via the one or more hardware processors, an additional morphological feature in the form of growth stage of the plant associated with the one or more leaves being monitored; and
estimating, via the one or more hardware processors, an age of every leaf from the identified one or more full leaves using a pre-trained multivariable linear regression model receiving one or more of the computed and received morphological features, wherein the multivariable linear regression model is pre-trained using the identified plant species, associated leaf shapes, morphological features of leaves of the identified plant species and age thereof.
