MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202631045423 A) filed by Dr. Rajendra Prasad Central Agricultural University, Samastipur, Bihar, on April 9, for 'non-destructive image-based method for estimation of photosynthetic pigments in plant leaves.'
Inventor(s) include Dr. Jyostnarani Pradhan.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a non-destructive image-based system and method for estimation of photosynthetic pigments in plant leaves and a process for developing predictive models for the same. The system comprises an imaging device configured to capture digital images of plant leaves under standardized imaging conditions and a computing module configured to extract image-derived features and estimate pigment concentrations using predictive models. The predictive models used are developed based on the correlation of the features with the biochemical pigment content, which is analyzed using conventional spectrophotometric analysis. The method allows the estimation of chlorophyll and carotenoid pigments from the leaves based on the leaf images. The invention allows the estimation of the pigments from the leaves without destroying the leaves."
