System & Product Summary
AgroVision AI is an agricultural diagnostic platform engineered to assist farmers in early detection of tomato and potato crop diseases. Built as a mobile-first solution using React Native and a Python FastAPI backend, the system processes field leaf images through OpenCV normalization filters before running inference against a custom Convolutional Neural Network (CNN).
Core Problem & Friction
Delayed crop disease classification leads to billions in annual agricultural losses. Farmers lack accessible, non-technical diagnostic tools that can function reliably under harsh field lighting conditions.
Systemic Constraints
95%+ model diagnostic accuracy, sub-2 second server inference times, low-bandwidth data payloads, and clean non-technical report structures.
Engineering Research
I researched image preprocessing algorithms. I found that raw images shot in varying sunlight conditions skew model classification weights. I analyzed OpenCV filters (histogram equalization, Gaussian blurs) to normalize inputs before inference.
Software Architecture
AI & Machine Learning Architecture
Engineered dedicated machine intelligence pipelines utilizing Custom CNN (TensorFlow / Keras) for inference and dynamic routing.
Solution Implementation
We engineered an image preprocessing pipeline utilizing OpenCV histogram equalization and Gaussian filtering to normalize sunlight glare, coupled with a server-side CNN inference endpoint returning confidence-scored diagnoses and dynamic treatment plans in under 1.5 seconds.
I rejected hosting the 180MB raw CNN model directly on-device in React Native. While on-device models offer offline capability, their download size degraded mobile app acquisition rates, so I opted for a FastAPI remote inference server that kept the mobile app footprint under 25MB.
I optimized the CNN architecture by quantizing convolutional layers, reducing server RAM footprint from 450MB to 75MB.
Quantifiable Impact & Metrics
98.2% diagnostic accuracy on tomato/potato crop evaluations, with reports and treatment recommendations returned in under 1.5 seconds.

Project Showcase
Lessons Learned & Takeaways
