SANYAMWADHWA.TECH :: PROJECT :: COGNIRECYCLE --- SUMMARY ---TITLE............. CogniRecycle — Smart City Waste ClassificationDATE.............. December 2025CATEGORY.......... ML & ResearchPROBLEM........... Waste contamination silently degrades recycling streams. One wrong item in a bin can spoil the whole batch. CogniRecycle watches the stream with two models, cross-checks every classification, and flags contamination as it happens.WHAT IT DOES...... Computer-vision waste sorting for smart city pipelines: a YOLO detector classifies waste materials in real time, and a second model cross-checks each result to flag contamination from mixed or incorrect disposal. --- RESULT ---METRIC 1.......... Dual-model verificationMETRIC 2.......... Multi-class detectionMETRIC 3.......... Real-time inference --- WHAT I BUILT ---HIGHLIGHT 1....... Dual-model inference pipeline: the primary YOLO model detects and classifies waste, a secondary model reviews each result for contamination, and the two outputs combine into one routing decision.HIGHLIGHT 2....... Trained on Garbage Classification Dataset 2 with a low-latency pipeline designed for camera and smart-bin integration. --- HOW IT WORKS ---STEP 1............ Camera / Image InputSTEP 2............ YOLO Detector (object detection + material classification)STEP 3............ Secondary Model (contamination check)STEP 4............ Post-processingSTEP 5............ Class + Contamination Status --- FEATURES ---FEATURE 1......... Real-time waste detection and material classification with YOLO (Ultralytics)FEATURE 2......... Multi-class recognition across plastic, paper, metal, glass, and other material typesFEATURE 3......... Secondary contamination model that catches mixed or incorrectly disposed wasteFEATURE 4......... Combined decision output: material class plus contamination status per itemFEATURE 5......... Low-latency inference pipeline built for smart bins, sorting systems, and recycling plants --- STACK ---STACK.............
