Echo is a system to detect street crimes like(Gunshot ,Burglary, Harrasment etc). It has an application on client side and a web portal on server side. Current progress only includes an independent application and machine learning model that detects gun shots.
We have a machine learning system in app that is trained on gunshots, and has an accuracy of 98% on Urban sound dataset.
Android, Machine Learning, SVM, HTML, CSS, Google Maps API
Wizard of Oz is a dummy application used to trigger our actual echo android application and works as a wizard of oz prototype for presentation purposes. Echo detects the sound "Echo" for now but doesn't communicate with the Machine Learning model. Machine Learning model is fully developed which uses SVM and it's demo video is provided in Project Information section.

We have processed assasination video of beynazir(a prominent Pakistani Politician) through our model which succesfully detected gunshot in the audio and displays text "GUN SHOT DETECTED" in red color at that instance. You can find it here. Machine Learning model's demo: https://youtu.be/ai2zxi55Lys
