IIT Mandi develops AI-based model for disease detection in potato crops using photos of leaves

New Delhi, July 12

Researchers on the Indian Institute of Know-how (IIT) Mandi, have developed a computational mannequin based mostly on Synthetic Intelligence (AI) for automated illness detection in potato crops utilizing pictures of its leaves.

The analysis in collaboration with the Central Potato Analysis Institute, Shimla, makes use of AI strategies to focus on the diseased parts of the leaf and has additionally been revealed within the journal — Plant Phenomics.

The computational device developed by IIT Mandi scientists can detect blight in potato leaf pictures. The mannequin is constructed utilizing an AI device known as masks region-based convolutional neural community structure and may precisely spotlight the diseased parts of the leaf amid a posh background of plant and soil matter.

The researchers are additional engaged on changing the developed device to a smartphone utility for extra sensible utilization.

In keeping with the staff, potatoes, within the historical past of the world, have been the reason for the nice famine of the mid-nineteenth century that killed over one million individuals in Eire and rang the loss of life knell for the Irish language. The explanation? Potato Blight.

“The blight is a standard illness of the potato plant, that begins as uneven gentle inexperienced lesions close to the tip and the margins of the leaf after which spreads into massive brown to purplish-black necrotic patches that finally results in rotting of the plant. If left undetected and unchecked, blight may destroy all the crop inside every week below conducive situations,” stated Srikant Srinivasan, Affiliate Professor, Faculty of Computing and Electrical Engineering, IIT Mandi.

“In India, as with most creating international locations, the detection and identification of blight are carried out manually by skilled personnel who scout the sector and visually examine potato foliage,” he stated including, this course of, as anticipated, is tedious and infrequently impractical, particularly for distant areas, as a result of it requires the experience of a horticultural specialist who might not be bodily accessible.

Joe Johnson, a analysis scholar at IIT Mandi defined that automated illness detection may help on this regard and given the in depth proliferation of cell phones throughout the nation, the smartphone could possibly be a great tool on this regard.

“The superior HD cameras, higher computing energy and communication avenues provided by smartphones provide a promising platform for automated illness detection in crops, which may save time and assist in the well timed administration of illnesses, in instances of outbreaks,” he stated.

For the analysis, with the intention to develop a strong mannequin, wholesome and diseased leaf knowledge have been collected from fields throughout Punjab, Uttar Pradesh and Himachal Pradesh.

“It was essential that the mannequin developed ought to have portability throughout the nation. Evaluation of the detection efficiency signifies an total precision of 98 per cent on leaf pictures in discipline environments,” Srinivasan stated.

The seven-member staff claimed regardless that potato is just not a staple meals in most areas of the world, it’s a money crop, and failure in it will probably have disastrous penalties, notably to farmers with marginal landholding.

Thus, early detection of blight is essential to stop monetary disaster to the farmer and the nation’s financial system.

“Following this success, we are actually sizing down the mannequin to a couple tens of megabytes in order that it may be hosted on a smartphone as an utility. With this, when the farmer will {photograph} the leaf which seems unhealthy, the appliance will verify in real-time if the leaf is contaminated or not,” stated Srinivasan.

“With this well timed information, the farmer would know precisely when to spray the sector, saving his produce and minimising prices related to pointless use of fungicides. The mannequin is being refined as extra states are coated,” added Srinivasan.

He additionally highlighted that it could be deployed as a part of the FarmerZone app that can be accessible to potato farmers without spending a dime.

The opposite members of the staff embrace Shyam Ok Masakapalli from IIT Mandi together with analysis students — Joe Johnson and Geetanjali Sharma, and Vijay Kumar Dua, Sanjeev Sharma and Jagdev Sharma from the Central Potato Analysis Institute, Shimla. PTI
