The estimating the chlorophyll contents in the crops helps to identify the condition of crops and different classification of crops with soil characteristics in order to assist the farmer or others with agriculture growth. In this paper, a hybrid approach is introduced to estimate the Chlorophyll contents in the crops using hyperspectral image segmentation with active learning, which consists of two main steps. First, we use a sparse multinomial logistic regression (SMLR) model to learn the class posterior probability distributions with Quadratic Programming or joint probability distribution. Second, we use the information acquired in the previous step to segment the hyper spectral image using a Markov Random field segments to estimate the dependencies using spatial information and edge Information by minimum spanning forest rooted on markers. In order to reduce the cost of acquiring large training sets, PSO optimization is performed based on the SMLR posterior probabilities on the Normalized difference vegetation index (NDVI). The state-of-the-art performance of the proposed approach is illustrated using real hyper spectral data sets collected from the North Karnataka in a number of experimental comparisons with recently developed or statistical hyperspectral image analysis methods in terms of precision, recall and f—measure.
