The Challenge & Our Solution
Traditional grape ripeness assessment is subjective, labor-intensive, and destructive, leading to inefficiencies in harvesting and sorting. Existing non-destructive methods often lack precision or computational efficiency, hindering real-time application in automated systems. The 'Improved-Res' model leverages multispectral imaging combined with advanced residual network architecture, incorporating SE attention, Depthwise Separable Convolutions (DSC), and Inception modules. Preprocessing steps like Gaussian denoising and ECC algorithm registration address image noise and misalignment, ensuring robust data for the model.
Improved-Res provides highly accurate, non-destructive sugar content prediction, enabling automated grape ripeness assessment. This enhances efficiency, reduces labor costs, and supports better decision-making for grape harvesting and sorting, driving the modernization of the agricultural industry.

Automated Grape Sorting in a Large Vineyard
A major vineyard faced challenges with manual grape sorting, leading to inconsistent quality and high labor costs. Implementing an AI-driven system based on multispectral imaging and a model similar to Improved-Res allowed for real-time, non-destructive assessment of sugar content for every grape cluster. This resulted in a 25% reduction in sorting time and a 15% increase in premium grape yield, significantly boosting profitability and product quality. The system's ability to accurately predict ripeness facilitated optimal harvest scheduling and ensured consistent product standards for wine production.
