DermaBot : Skin Disease Detection & FAQ Chatbot

Demo

A web app that detects skin conditions from uploaded images and provides educational answers through a FAQ chatbot.

Problem Solved

Early skin condition identification is often delayed because people don't know what they're dealing with or where to start.

Computer Vision / Classification

VGG Trash Image Classifier

Demo

A deep learning classifier that sorts trash images into categories : plastic, cardboard, glass, metal, paper, and general waste : using VGG16.

Problem Solved

Manual waste sorting is inconsistent and labor-intensive. An automated classifier can improve recycling efficiency.
